Soil organic matter depletion is a significant concern in agricultural soils, impacting crucial aspects of ecosystem health, especially soil properties such as fertility and soil moisture retention. Adopting sustainable soil management practices, such as cover crops, can mitigate this issue. In this study, we analyzed the soil organic carbon (SOC) content and quality in vineyards using two distinct management methods: permanent spontaneous cover crops and conventional tillage. Dissolved organic carbon (DOC) was quantified and chemically characterized using UV\u2013visible spectroscopy. Our results showed an increase of 4.7 Mg C/ha in the carbon stock (50 cm depth) after 10 years of implementing vegetation covers compared with tilled soil. Additionally, cover crop management increased less humified soluble carbon in surface soil layers, while tillage transformed the solubilized carbon. This finding is important because tilled soil becomes more accessible to microbial degradation and leaching, which, in the long term, leads to a SOM content decrease. In conclusion, an increase in carbon stock was observed when using cover crops due to the incorporation of fresh organic matter, whereas tilled soils showed a depletion of carbon stock, including the mobilization of more stable carbon.

Nutrient release from legume and cereal crop residue is important to N crycling and the success of conservation and sustainable farming systems. Residue type, placement, and degree of incorporation, and soil water regimes largely control availability and loss of soil N and were evaluated in the laboratory. Four residues, i.e., vetch (Vicia villosa Roth.), soybean (Glycine max [L.] Merr.), corn (Zea mays L.), and wheat (Triticum aestivum L.) having C/N ratios ranging from 8 to 82 were applied on the soil surface or incorporated in repacked cores of a Nicollet loam (fine\uffe2\uff80\uff90loamy, mixed, mesic Aquic Hapludoll) and incubated for 17 or 35 d at 60 and 90% water\uffe2\uff80\uff90filled pore space (WFPS) with enriched 15N\uffe2\uff80\uff90NO3 (76.7%). Denitrification losses from all treatments were negligible at 60% WFPS. At 90% WFPS, total denitrification losses from residue\uffe2\uff80\uff90incorporated soils represented 87 to 127% of the initial soil NO3 level (80.5 mg N kg\uffe2\uff88\uff921); losses increased with decreasing residue C/N ratio. Denitrification was greatest during the first 8 d, as was CO2 evolution. Initial denitrification with surface\uffe2\uff80\uff90placed residues was less than with incorporated residues, but cumulative losses over 35 d did not differ significantly. Substantial N immobilization occurred with incorporated or surface\uffe2\uff80\uff90placed wheat, corn, and soybean residue with wide C/N ratios at 60% WFPS, whereas, with low\uffe2\uff80\uff90C/N\uffe2\uff80\uff90ratio vetch, significant mineralization occurred. After 35 d, 51 and 36% of N in incorporated and surface\uffe2\uff80\uff90placed vetch residue, respectively, was mineralized. Residue C/N ratio was inversely related to initial rates of residue decomposition, and effects of residue type and placement and soil water on denitrification and mineralization were most important during early (8\uffe2\uff80\uff9010 d) decomposition.

Deforestation is one of the main reasons for the global net release of CO2 from soil to atmosphere. Estimates of CO2 emission from soils are highly variable, mainly due to limited data of C dynamics in soils after forest clearing. The objective of this study was to calculate the changes in soil organic carbon (SOC) storage after deforestation in three soil types in the Atlantic Zone of Costa Rica with help of the \uffce\uffb413C method. Changes in bulk density, which normally accompany land use changes, had a profound influence on the results of the calculations. Deforestation, followed by 25 yr of pasture, caused a net loss of 21.8 Mg ha\uffe2\uff88\uff921 in SOC for an Eutric Hapludand and 1.5 Mg ha\uffe2\uff88\uff921 for an Oxic Humitropept. The SOC changes in time were studied on a deforestation sequence on an Andic Humitropept. In the first years after forest clearing, decomposition of tree roots caused an extra input of SOC, which influenced the \uffce\uffb413C signal. Decomposition of forest C and increase of pasture C were mathematically described for several depths. A considerable influence of depth on decomposition rates was found. The strong stabilization of organic C by Al\uffe2\uff80\uff90organic matter complexes probably caused the relatively small net C loss from SOC since forest clearing.

To minimize groundwater contamination by NO\uffe2\uff88\uff923 and to maximize efficient crop N use, it is necessary to better characterize NO\uffe2\uff88\uff923 leaching in various cropping systems. Our objectives were to compare the contributions of hairy vetch (Vicia villosa Roth) and NH+4 N sources to NO\uffe2\uff88\uff923 leaching in corn (Zea mays L.) production, and to compare NO\uffe2\uff88\uff923 leaching losses in a corn production system utilizing hairy vetch as a N source and winter cover crop with leaching losses in one utilizing an NH+4 N source and a rye (Secale cereale L.) cover crop. Nitrogen, sometimes enriched with 15N, was applied to corn grown on a Maury silt loam (fine, mixed, mesic Typic Paleudalf) in lysimeters as vetch\uffe2\uff80\uff90 or NH+4\uffe2\uff80\uff90N at rates between 10.5 and 14.0 g N m\uffe2\uff88\uff922 yr\uffe2\uff88\uff921. Treatments (N source/cover crop) were: NH+4\uffe2\uff80\uff90N/fallow, vetch\uffe2\uff80\uff90N/fallow, NH+4\uffe2\uff80\uff90N/rye, and vetch\uffe2\uff80\uff90N/vetch; mean 3\uffe2\uff80\uff90yr cumulative NO\uffe2\uff88\uff923 leaching losses were 6.11, 4.85, 0.35, and 2.51 g N m\uffe2\uff88\uff922, respectively. Total recovery of added 15N in leachate was <5% for all treatments, and the percentage of leached NO\uffe2\uff88\uff923 derived from labeled N sources was generally <15%. In the winter\uffe2\uff80\uff90fallow lysimeters, effects of N source on the fraction of water input discharged, concentration of NO\uffe2\uff88\uff923, and quantity of NO\uffe2\uff88\uff923 leached varied with year and time of year; differences in N\uffe2\uff80\uff90source availability and mulch effects were sometimes indicated. Generally, cover crop effects were larger than N\uffe2\uff80\uff90source effects. The NH+4 N source/rye cover system leached consistently less NO\uffe2\uff88\uff923 than the vetch N source/vetch cover system, even though the fraction of water discharged was not consistently different.

The first area was a pastured dehesa (P) with young Holm oaks, planted in 1995 (70 trees ha\u22121, 12 m \u00d7 12 m) and, since 2000, grazed by sheep (3 sheep ha\u22121) with an average period of grazing of six months a year. Prior to this it was managed in the same way as the second adjacent area. The second area was a cropped dehesa (C) with widely spaced mature Holm oak (14 trees in a 12-ha dehesa), on which a mixture of vetch and oats was cultivated every three years and tilled with a chisel plough. After 22 years both dehesas showed similar SOC stock distribution amongst areas with different soil management, with approximately 40 t ha\u22121 in the top 100 cm of the soil. The P dehesa only showed higher SOC stock than the C dehesa on the surface 0\u20132 cm (5.86 \u00b1 0.56 t ha-1vs 3.24 \u00b1 0.37 t ha\u22121). The influence of the trees, increasing SOC concentration and content when compared to the area outside the canopy projection, was only detected under the mature trees in the C dehesa. In the area outside the tree canopy, both systems showed a similar distribution of soil organic carbon among their different fractions, with the unprotected fraction being the dominant one, followed by the physically and chemically protected fractions. In the C dehesa, the mature trees\u2019 presence significantly modified the distribution of soil organic carbon in their surroundings, increasing the relevance of the unprotected fraction. The distribution of soil organic carbon in the unprotected and physically and chemically protected fractions were strongly correlated to the overall organic carbon concentration in the soil, indicating the rapid response of these three fractions to management, with the biochemically protected fraction showing no correlation, suggesting a high resilience to the changes in carbon budget.

Soils and soil solutions were collected from adjacent ceanothus (Ceanothus velutinus Dougl.) and Jeffrey pine (Pinus jeffreyi Grev. & Balf) stands in Little Valley, Nevada. It was hypothesized that excessive N fixation by ceanothus, like red alder (Alnus rubra Bong.), causes accelerated nitrification, NO\uffe2\uff88\uff923 leaching, and soil acidification. This hypothesis was not supported. Comparisons of soils from five paired ceanothus\uffe2\uff80\uff90pine plots showed that ceanothus soils not only had greater C and N concentrations, but also greater cation\uffe2\uff80\uff90exchange capacity, base saturation, and exchangeable Ca2+, Mg2+, and K+ than pine soils. There were no significant differences in extractable P or SO2\uffe2\uff88\uff924 overall, although there were differences at some sites. Extractable P levels were quite high relative to more humid forest soils, whereas extractable SO2\uffe2\uff88\uff924 levels were very low. Soil solutions from ceanothus, pine, and a riparian mountain alder (Alnus tenuifolia Nutt.) stand were characterized by low NO\uffe2\uff88\uff923 concentrations, circumneutral pH, and high base cation, HCO\uffe2\uff88\uff923, SO2\uffe2\uff88\uff924, Cl\uffe2\uff88\uff92, and Si concentrations. The chemical composition of nearby streamwaters was similar to that of soil solutions with respect to NO\uffe2\uff88\uff923, pH, HCO\uffe2\uff88\uff923, and base cation and Si concentrations. Streamwater SO2\uffe2\uff88\uff924 and Cl\uffe2\uff88\uff92 concentrations (\uffe2\uff89\uff88 3\uffe2\uff80\uff9317 \uffc2\uffb5molc L\uffe2\uff88\uff921) were more than an order of magnitude lower than those in soil solutions (\uffe2\uff89\uff88 150\uffe2\uff80\uff93270 \uffc2\uffb5molc L\uffe2\uff88\uff921), however, indicating that soils adjacent to the stream had little influence on its chemistry. Thus, the NO\uffe2\uff88\uff923 pulse (from <1 to \uffe2\uff89\uff88 30 \uffc2\uffb5molc L\uffe2\uff88\uff921) measured in both streamwaters and ceanothus soil solutions during snowmelt most likely originated from the melting snowpack.

Abstract. Evaporation (E) and transpiration (T) respond differently to ongoing changes in climate, atmospheric composition, and land use. It is difficult to partition ecosystem-scale evapotranspiration (ET) measurements into E and T, which makes it difficult to validate satellite data and land surface models. Here, we review current progress in partitioning E and T and provide a prospectus for how to improve theory and observations going forward. Recent advancements in analytical techniques create new opportunities for partitioning E and T at the ecosystem scale, but their assumptions have yet to be fully tested. For example, many approaches to partition E and T rely on the notion that plant canopy conductance and ecosystem water use efficiency exhibit optimal responses to atmospheric vapor pressure deficit (D). We use observations from 240 eddy covariance flux towers to demonstrate that optimal ecosystem response to D is a reasonable assumption, in agreement with recent studies, but more analysis is necessary to determine the conditions for which this assumption holds. Another critical assumption for many partitioning approaches is that ET can be approximated as T during ideal transpiring conditions, which has been challenged by observational studies. We demonstrate that T can exceed 95\uffe2\uff80\uff89% of ET from certain ecosystems, but other ecosystems do not appear to reach this value, which suggests that this assumption is ecosystem-dependent with implications for partitioning. It is important to further improve approaches for partitioning E and T, yet few multi-method comparisons have been undertaken to date. Advances in our understanding of carbon\uffe2\uff80\uff93water coupling at the stomatal, leaf, and canopy level open new perspectives on how to quantify T via its strong coupling with photosynthesis. Photosynthesis can be constrained at the ecosystem and global scales with emerging data sources including solar-induced fluorescence, carbonyl sulfide flux measurements, thermography, and more. Such comparisons would improve our mechanistic understanding of ecosystem water fluxes and provide the observations necessary to validate remote sensing algorithms and land surface models to understand the changing global water cycle.

Eighteen years after the establishment of a loblolly pine (Pinus taeda L.) plantation, ecosystem C content had approximately tripled (from 54 to 161 Mg C ha\uffe2\uff88\uff921) primarily because of increases in tree biomass.

No statistically significant changes in soil C were found. Growth responses to fertilization noted in Year 4 were no longer statistically significant in Year 18. Nitrogen accumulation in aboveground biomass and forest floor were approximately equal (averaging approximately 270 kg N ha\uffe2\uff88\uff921 each) and could have come from a combination of atmospheric deposition, soil N mineralization, and, in the treated plots, fertilizer input. No statistically significant changes in soil N content were found.

Forest harvesting and regeneration may cause changes in soil and solution chemistry that adversely affect environmental quality. Organic C content in the forest floor and mineral soil, and dissolved organic carbon (DOC) fractions in the soil solution and groundwater were investigated in a black spruce [Picea mariana (Miller) BSP] swamp 5 yr after the application of two silvicultural prescriptions: whole\uffe2\uff80\uff90tree harvest only and whole\uffe2\uff80\uff90tree harvest followed by site preparation bedding. Soil organic carbon (SOC) content in the forest floor of both treatments were significantly lower than that of an uncut control stand. However, SOC in the upper 50 cm of mineral soil of the bedded treatment was similar to that of the control, while both were about 20% higher than SOC in the harvest\uffe2\uff80\uff90only treatment. Total DOC concentrations ranged from 12 to 87 mg/L in the soil solution and 6 to 46 mg/L in the groundwater and did not differ among treatments. Hydrophobic acids were the dominant DOC fraction across all treatments, but the proportion of hydrophobic strong acids increased at the expense of hydrophilic acids in the harvest\uffe2\uff80\uff90only treatment. Carboxyl content of hydrophilic acids in the soil water was 7.0 mmol/g hydrophilic compound in the control stand and 4.4 mmol/g in the treatments. Hydrophobic acid carboxyl content across treatments was 4.6 mmol/g hydrophobic substance. Relative to C loss and changes in water chemistry, these results indicate that 5 yr after whole\uffe2\uff80\uff90tree harvesting, this forest site has not yet fully equilibrated.

Abstract. Measuring in situ soil fluxes of carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O) continuously at high frequency requires appropriate technology. We tested the combination of a commercial automated soil CO2 flux chamber system (LI-8100A) with a CH4 and N2O analyzer (Picarro G2308) in a tropical rainforest for 4\u00a0months. A chamber closure time of 2\u2009min was sufficient for a reliable estimation of CO2 and CH4 fluxes (100\u2009% and 98.5\u2009% of fluxes were above minimum detectable flux \u2013 MDF, respectively). This closure time was generally not suitable for a reliable estimation of the low N2O fluxes in this ecosystem but was sufficient for detecting rare major peak events. A closure time of 25\u2009min was more appropriate for reliable estimation of most N2O fluxes (85.6\u2009% of measured fluxes are above MDF\u2009\u00b1\u20090.002\u2009nmol\u2009m\u22122\u2009s\u22121). Our study highlights the importance of adjusted closure time for each gas.

The need for greener processes to satisfy the demand of platform chemicals together with the possibility of reusing CO2 from human activities has recently encouraged research on the set-up, optimization, and development of bioelectrochemical systems (BESs) for the electrosynthesis of organic compounds from inorganic carbon (CO2, HCO3\u2212). In the present study, we tested the ability of Clostridium saccharoperbutylacetonicum N1-4 (DSMZ 14923) to produce acetate and D-3-hydroxybutyrate from inorganic carbon present in a CO2:N2 gas mix. At the same time, we tested the ability of a Shewanella oneidensis MR1 and Pseudomonas aeruginosa PA1430/CO1 consortium to provide reducing power to sustain carbon assimilation at the cathode. We tested the performance of three different systems with the same layouts, inocula, and media, but with the application of 1.5 V external voltage, of a 1000 \u2126 external load, and without any connection between the electrodes or external devices (open circuit voltage, OCV). We compared both CO2 assimilation rate and production of metabolites (formate, acetate 3-D-hydroxybutyrate) in our BESs with the values obtained in non-electrogenic control cultures and estimated the energy used by our BESs to assimilate 1 mol of CO2. Our results showed that C. saccharoperbutylacetonicum NT-1 achieved the maximum CO2 assimilation (95.5%) when the microbial fuel cells (MFCs) were connected to the 1000 \u2126 external resistor, with the Shewanella/Pseudomonas consortium as the only source of electrons. Furthermore, we detected a shift in the metabolism of C. saccharoperbutylacetonicum NT-1 because of its prolonged activity in BESs. Our results open new perspectives for the utilization of BESs in carbon capture and electrosynthesis of platform chemicals.

Artemisia tridentata Nutt. is a prominent shrub of cool deserts in the USA that influences the patterns of chemistry and microbiological activity in the soil in which it grows. However, little is known about the fate of these patterns following the death or removal of the live A. tridentata plant. We compared abutting burned and unburned sites to see if patterns in soil could be related to locations where shrubs were removed by fire 9 yr earlier. While most soil variables were significantly higher in the unburned site than in the burned site, total organic C and soil pH appear unaffected by the removal of A. tridentata or the fire itself. Differences between unburned and burned sites were greatest near the location of a plant axis. In contrast, burned soil was not distinguishable from unburned soil at distances greater than \uffe2\uff89\uff88 50 cm away from a live A. tridentata axis or a charred stump indicating that soil patterns were most affected by removal of the plant and not by the fire. Nearly a decade after the fire, significant effects of A. tridentata on patterns of some soil variables in the burned site were still detectable. Significantly higher values for total organic C, total N, water soluble C, electrical conductivity, and soil microbial biomass C were observed near the location of charred A. tridentata stumps than at distances further away. These patterns are a significant source of soil variability that may be difficult to account for because they are not related to the obvious location of live plants.

Potato production faces increasingly severe agronomic problems, including intensive production and pedoclimatic changes. Increasing pest/disease incidence is contributing to inadequate application of pesticides and external fertilizers. This study aims to identify critical agri-environmental challenges currently faced by potato growers in Europe, assessing the needs and priorities of end-users to determine the feasibility of integrating more sustainable farming practices into potato cultivation. Additionally, we identified sustainable strategies to reduce reliance on external inputs. A total of 203 potato stakeholders from six European pedoclimatic areas completed a survey in 2020 to identify agronomic and environmental problems, priorities for action, and best-suited sustainable farming practices. Statistical and multicriteria decision analysis was then performed. Subsequently, focus group meetings with stakeholders were organized to present and discuss results and validate and complement them. Stakeholders perceived that more sustainable potato production involved reducing tillage intensity, using organic nutrient sources, increasing soil organic matter and, especially, diversifying crop rotations. Barriers to adopting new sustainable practices included farmers\u2019 lack of knowledge regarding novel farming practices and the need for expert technical advice. Some practices are complex, but also economic impediments. Therefore, thorough research, clear demonstrations, and tailored advice are crucial to farmers to lead agriculture toward profitable, sustainable systems.

In ponderosa pine (Pinus ponderosa Douglas ex P. Lawson & Lawson)\uffe2\uff80\uff90bunchgrass ecosystems of the western USA, fire exclusion by Euro\uffe2\uff80\uff90American settlers facilitated pine invasion of grassy openings, increased forest floor detritus, and shifted the disturbance regime toward stand\uffe2\uff80\uff90replacing fires, motivating ecological restoration through thinning and prescribed burning. We used in situ soil respiration over a 2\uffe2\uff80\uff90yr period to assess belowground responses to pine invasion and restoration in a ponderosa pine\uffe2\uff80\uff90bunchgrass ecosystem near Flagstaff, AZ. Replicated restoration treatments were: (i) partial restoration \uffe2\uff80\uff94 thinning to presettlement conditions; (ii) complete restoration \uffe2\uff80\uff94 removing trees and forest floor material to presettlement conditions, native grass litter addition, and prescribed burning; and (iii) control. Within treatments, we sampled beneath different canopy types to assess the effects of pine invasion into grassy openings on soil respiration. Growing season soil respiration was greater in the complete restoration (346 \uffc2\uffb1 24 g CO2\uffe2\uff80\uff90C m\uffe2\uff80\uff902) and control (350 \uffc2\uffb1 8 g CO2\uffe2\uff80\uff90C m\uffe2\uff80\uff902) than the partial restoration (301 \uffc2\uffb1 5 g CO2\uffe2\uff80\uff90C m\uffe2\uff80\uff902) in 1995. In 1996, the complete (364 \uffc2\uffb1 17 g CO2\uffe2\uff80\uff90C m\uffe2\uff80\uff902) and partial (328 \uffc2\uffb1 7 g CO2\uffe2\uff80\uff90C m\uffe2\uff80\uff902) restoration treatments had greater growing season respiration rates than the control (302 \uffc2\uffb1 13 g CO2\uffe2\uff80\uff90C m\uffe2\uff80\uff902). Results suggest that restoration effects on soil respiration depend on interannual soil water patterns and may not significantly alter regional C cycles. Soil respiration from grassy openings was 15% greater than from soil beneath presettlement or postsettlement pines in 1995 and 1996. A lack of active management will decrease belowground catabolism if pines continue to expand at the expense of grassy openings.

Tillage intensity affects soil structure and the loss of soil organic C and N. We hypothesized that no\uffe2\uff80\uff90tillage (NT) and conventional tillage (CT) differentially affect three physically defined particulate organic matter (POM) fractions. A grassland\uffe2\uff80\uff90derived Haplustoll was separated into aggregates by wet sieving. Free light fraction (LF) and intra\uffe2\uff80\uff90aggregate POM (iPOM) were isolated. Natural abundance 13C was measured for whole soil C, free LF C, and iPOM C. The mean residence time of soil C under CT (44 yr) was 1.7 times less than in NT (73 yr). The amount of free LF C was 174, 196, and 474 g C m\uffe2\uff80\uff902 for CT, NT, and NS, respectively. Total iPOM C amounts in CT, NT, and NS were 193, 337, and 503 g C m\uffe2\uff80\uff902, respectively. The level of fine iPOM C (53\uffe2\uff80\uff93250 \uffc2\uffb5m) level in macroaggregates (250\uffe2\uff80\uff932000 \uffc2\uffb5m) obtained after slaking was five times greater in NT vs. CT and accounted for 47.3% of the difference in total POM C between NT and CT. The amount of coarse iPOM C (250\uffe2\uff80\uff932000 \uffc2\uffb5m) was only 2.4 times greater and accounted for only 21% of the difference in total POM C. Sequestration of iPOM was observed in NT vs. CT, but free LF was not influenced by differential tillage. We conclude that differences in aggregate turnover largely control the difference in fine iPOM in CT vs. NT and consequently SOM loss is affected by both the amount of aggregation and aggregate turnover.

Abstract. Researchers have known for decades that silicon plays a major role in biogeochemical and plant-soil processes in terrestrial systems. Meanwhile, plant biologists continue to uncover a growing list of benefits derived from silicon to combat abiotic and biotic stresses, such as defense against herbivory. Yet despite growing recognition of herbivores as important ecosystem engineers, many major gaps remain in our understanding of how silicon and herbivory interact to shape biogeochemical processes, particularly in natural systems. We review and synthesize 119 available studies directly investigating silicon and herbivory to summarize key trends and highlight research gaps and opportunities. Categorizing studies by multiple ecosystem, plant, and herbivore characteristics, we find substantial evidence for a wide variety of important interactions between plant silicon and herbivory, but highlight the need for more research particularly in non-graminoid dominated vegetation outside of the temperate biome as well as on the potential effects of herbivory on silicon cycling. Continuing to overlook silicon-herbivory dynamics in natural ecosystems limits our understanding of potentially critical animal-plant-soil feedbacks necessary to inform land management decisions and to refine global models of environmental change.

Intensively managed plantations of trees occupy vast areas of the tropics. The productivity of these forests depends strongly on nutrient supply, and nutrient supply may change rapidly under intensive management regimes. We documented changes in a Hawaiian soil after 32 mo of development of a plantation of eucalyptus [Eucalyptus saligna (Sm.)]. Soil C did not change significantly (average = \uffe2\uff80\uff9023 g C m\uffe2\uff80\uff902 yr\uffe2\uff80\uff901 to 30 cm; 95% confidence \uffe2\uff88\uff92139 to +93 g C m\uffe2\uff80\uff902 yr\uffe2\uff80\uff901). This lack of change in soil C resulted from a rapid loss of older soil C derived from sugarcane (\uffe2\uff88\uff92191 g C m\uffe2\uff80\uff902 yr\uffe2\uff80\uff901) and a rapid gain of new soil C from eucalyptus (160 g C m\uffe2\uff80\uff902 yr\uffe2\uff80\uff901). Soil N declined by 19 g N m\uffe2\uff80\uff902 yr\uffe2\uff80\uff901 (P = 0.08), despite fertilizer additions of 31 to 70 g m\uffe2\uff80\uff902. Large reductions in exchangeable Ca and Mg probably resulted from dissolution and leaching of residual lime from prior agricultural management. We conclude that intensive sampling regimes may detect relatively small changes in tropical forest soils, and that expectations of C accumulation in soils following afforestation may need to be reconsidered.

The \u03b4 13 C of cultivated soil profiles that had been under continuous corn for 8 to 35 yr increased in all depth increments above that of the noncultivated profiles. The percentage of soil organic C (SOC) derived from corn residues and roots ranged from 22 to 40% of the total C. The proportion of corn-derived C, as determined by this technique, decreased with soil depth and was minimal in the 50- to 100-cm depth increments of fine-textured soils. The mean residence time of the non-corn C (C 3 ) ranged from 36 to 108 yr at the surface, and up to 769 yr at the subsoil depth. The longer turnover times were associated with soils high in clay. Prairie-derived soils have a higher potential to sequester C than those derived from forests. The significant loss of total C at all sites and the slow turnover times of the incorporated C lead us to conclude that there is a substantial potential for soils to serve as a C sink and as a significant nutrient reserve in sustainable agriculture.", "keywords": ["soil organic carbon", "2.

Carbon and nutrients in the forest floor and mineral soil were measured to determine amounts and variation among eighteen 0.081\uffe2\uff80\uff90ha plots in a Douglas\uffe2\uff80\uff90fir [Pseudotsuga menziesii (Mirb.) Franco] plantation growing with volunteer red alder (Alnus rubra Bong.). Ten years earlier, the preceding mature conifer stand was clearcut and nearly all logging slash and forest floor were consumed by slash fire. Forest floor mass in the 9\uffe2\uff80\uff90yr\uffe2\uff80\uff90old plantation averaged 9.86 Mg ha\uffe2\uff80\uff901, with 3.71 Mg C, 98.0 kg N, 10.6 kg P, and 8.4 kg S ha\uffe2\uff80\uff901. Mineral soil to 1\uffe2\uff80\uff90m depth averaged 176 Mg C, 8330 kg N, 3340 kg P, and 605 kg S ha\uffe2\uff80\uff901 in the <2\uffe2\uff80\uff90mm fraction. The 2\uffe2\uff80\uff90 to <6\uffe2\uff80\uff90mm soil fraction averaged an additional 100 Mg C, 4480 kg N, and 1700 kg P ha\uffe2\uff80\uff901. Net mineralizable N as NH4 (anaerobic N mineralization index) totaled 99 kg N ha\uffe2\uff80\uff901 in the top 45 cm of the mineral soil and 62 kg N ha\uffe2\uff80\uff901 in the 45\uffe2\uff80\uff90 to 100\uffe2\uff80\uff90cm depth. Density fractionation showed that the light fraction (<1.65 Mg m\uffe2\uff80\uff903) was only 13.4% of the fine soil mass of the 0\uffe2\uff80\uff90 to 15\uffe2\uff80\uff90cm depth, yet contained about 40% of the total C and N capital in the <2\uffe2\uff80\uff90mm size fraction. The substantial amounts of C and nutrients in this low\uffe2\uff80\uff90bulk density soil (<2\uffe2\uff80\uff90mm fraction, 0.30 Mg m\uffe2\uff80\uff903) indicate a fertile soil despite large previous losses of organic matter and N from the site.

No\uffe2\uff80\uff90till (NT) increases the potential to crop more frequently in the Great Plains than with the conventional\uffe2\uff80\uff90till (CT) crop\uffe2\uff80\uff93fallow farming system. More frequent cropping requires N input to maintain economical yields. We evaluated the effects of N fertilization on crop residue production and its subsequent effects on soil organic C (SOC) and total soil N (TSN) in a dryland NT annual cropping system. Six N rates (0, 22, 45, 67, 90, and 134 kg N ha\uffe2\uff88\uff921) were applied to the same plots from 1984 through 1994, except 1988 when rates were reduced 50%, on a Weld silt loam (fine, smectitic, mesic Aridic Argiustoll). Spring barley (Hordeum vulgare L.), corn (Zea mays L.), winter wheat (Triticum aestivum L.), and oat (Avena sativa L.)\uffe2\uff80\uff93pea (Lathyrus tingitanus L.) hay were grown in rotation. Crop residue production varied with crop and year. Estimated average annual aboveground residue returned to the soil (excluding hay years) was 2925, 3845, 4354, 4365, 4371, and 4615 kg ha\uffe2\uff88\uff921, while estimated annual contributions to belowground (root) residue C were 1060, 1397, 1729, 1992, 1952, and 2031 kg C ha\uffe2\uff88\uff921 for the above N rates, respectively. The increased amount of crop residue returned to the soil with increasing N rate resulted in increased SOC and TSN levels in the 0\uffe2\uff80\uff90 to 7.5\uffe2\uff80\uff90cm soil depth after 11 crops. The fraction of applied N fertilizer in the crop residue decreased with increasing N rate. Soil bulk density (Db) in the 0\uffe2\uff80\uff90 to 7.5\uffe2\uff80\uff90cm soil depth decreased as SOC increased. The increase in SOC with N fertilization contributes to improved soil quality and productivity, and increased efficiency of C sequestration into the soil. Carbon sequestration can be enhanced by increasing crop residue production through adequate N fertility.

Abstract. Boreal forest soils are globally an important sink for methane (CH4), while these soils are also capable of emitting CH4 under favourable conditions. Soil wetness is a well-known driver of CH4 flux, and the wetness can be estimated with several terrain indices developed for the purpose. The aim of this study was to quantify the spatial variability of the forest floor CH4 flux with a topography-based upscaling method connecting the flux with its driving factors. We conducted spatially extensive forest floor CH4 flux and soil moisture measurements, complemented by ground vegetation classification, in a boreal pine forest. We then modelled the soil moisture with a random forest model using digital-elevation-model-derived topographic indices, based on which we upscaled the forest floor CH4 flux. The modelling was performed for two seasons: May\uffe2\uff80\uff93July and August\uffe2\uff80\uff93October. Additionally, we evaluated the number of flux measurement points needed to get an accurate estimate of the flux at the whole study site merely by averaging. Our results demonstrate high spatial heterogeneity in the forest floor CH4 flux resulting from the soil moisture variability as well as from the related ground vegetation. The mean measured CH4 flux at the sample points was \uffe2\uff88\uff925.07\uffe2\uff80\uff89\uffc2\uffb5mol\uffe2\uff80\uff89m\uffe2\uff88\uff922\uffe2\uff80\uff89h\uffe2\uff88\uff921 in May\uffe2\uff80\uff93July and \uffe2\uff88\uff928.67\uffe2\uff80\uff89\uffc2\uffb5mol\uffe2\uff80\uff89m\uffe2\uff88\uff922\uffe2\uff80\uff89h\uffe2\uff88\uff921 in August\uffe2\uff80\uff93October, while the modelled flux for the whole area was \uffe2\uff88\uff927.42 and \uffe2\uff88\uff929.91\uffe2\uff80\uff89\uffc2\uffb5mol\uffe2\uff80\uff89m\uffe2\uff88\uff922\uffe2\uff80\uff89h\uffe2\uff88\uff921 for the two seasons, respectively. The spatial variability in the soil moisture and consequently in the CH4 flux was higher in the early summer (modelled range from \uffe2\uff88\uff9212.3 to 6.19\uffe2\uff80\uff89\uffc2\uffb5mol\uffe2\uff80\uff89m\uffe2\uff88\uff922\uffe2\uff80\uff89h\uffe2\uff88\uff921) compared to the autumn period (range from \uffe2\uff88\uff9214.6 to \uffe2\uff88\uff922.12\uffe2\uff80\uff89\uffc2\uffb5mol\uffe2\uff80\uff89m\uffe2\uff88\uff922\uffe2\uff80\uff89h\uffe2\uff88\uff921), and overall the CH4 uptake rate was higher in autumn compared to early summer. In the early summer there were patches emitting high amounts of CH4; however, these wet patches got drier and smaller in size towards the autumn, changing their dynamics to CH4 uptake. The mean values of the measured and modelled CH4 fluxes for the sample point locations were similar, indicating that the model was able to reproduce the results. For the whole site, upscaling predicted stronger CH4 uptake compared to simply averaging over the sample points. The results highlight the small-scale spatial variability of the boreal forest floor CH4 flux and the importance of soil chamber placement in order to obtain spatially representative CH4 flux results. To predict the CH4 fluxes over large areas more reliably, the locations of the sample points should be selected based on the spatial variability of the driving parameters, in addition to linking the measured fluxes with the parameters.

Intensive site preparation for forest tree planting may result in a mid\uffe2\uff80\uff90rotation decline in soil N availability. Such decline has not been fully documented. This study was conducted in a loblolly pine (Pinus taeda L.) plantation in the Piedmont of North Carolina to evaluate the effects of nutrient removal during harvest and site preparation on N availability at mid\uffe2\uff80\uff90rotation. Treatments, installed in 1981, consisted of a combination of harvest (stem\uffe2\uff80\uff90only vs. whole\uffe2\uff80\uff90tree) and site preparation (chop and burn vs. shear, pile, and disk), with a split\uffe2\uff80\uff90plot of vegetation control (no herbicide vs. herbicide). In 1995 net N mineralization was examined by monthly in situ soil incubations from May through November (7 mo). Net N mineralization was approximately 3 times lower at mid\uffe2\uff80\uff90rotation than shortly after treatment. A 5\uffc2\uffb0C drop in soil temperature at 10\uffe2\uff80\uff90cm depth helped explain \uffe2\uff89\uff8850% of this decline. At mid\uffe2\uff80\uff90rotation, harvest intensity, but not site preparation intensity, affected N mineralization, with stem\uffe2\uff80\uff90only harvest plots mineralizing 11 kg N ha\uffe2\uff88\uff921 more than whole\uffe2\uff80\uff90tree harvest plots during the seven months.

Mid\uffe2\uff80\uff90rotation mineralization was positively correlated with soil temperature and negatively correlated with soil P and soil C:N ratio. The effect of harvest on N mineralization was probably exerted through P nutrition, whereas the lack of site preparation effects suggested that large nutrient removals that occurred with shearing and piling did not have lasting and negative effects on N availability in this plantation.

Data from a 14\uffe2\uff80\uff90yr double\uffe2\uff80\uff90crop rice (Oryza sativa L.) experiment allowed comparison of the long\uffe2\uff80\uff90term effects of N fertilizer from different sources (urea and in situ grown azolla [Azolla microphylla Kaulf.] and sesbania [Sesbania rostrata Bremek. & Oberm.]) on N balances, soil N pools (both total and available), and yields. Although data show that plant\uffe2\uff80\uff90available N was maintained over time in both wet (WS) and dry seasons (DS), yields declined significantly, indicating a decline in physiological N use efficiency. The yield declines were generally similar regardless of N source in both seasons. The WS decline averaged 150 kg ha\uffe2\uff88\uff921 yr\uffe2\uff88\uff921 in the three added\uffe2\uff80\uff90N treatments, while the DS decline averaged 185 kg ha\uffe2\uff88\uff921 yr\uffe2\uff88\uff921. After 27 crops, the cumulative positive N balance was estimated at 1244, 348, 646, and 1039 kg N ha\uffe2\uff88\uff921 in control, urea, sesbania, and azolla treatments, respectively. There was no significant change in soil total N content in the control and urea treatments, whereas it increased to 344 to 541 kg after 27 crops in the sesbania and azolla treatments. Conservation of the soil N status and positive N balance, in spite of the high amounts of N removed through grain and straw, reflect the N contribution (13\uffe2\uff80\uff9346 kg ha\uffe2\uff88\uff921 crop\uffe2\uff88\uff921) from nonsymbiotic N2 fixation. In addition, sesbania and azolla were estimated to add \uffe2\uff89\uff8857 to 64 kg ha\uffe2\uff88\uff921 crop\uffe2\uff88\uff921 through symbiotic N2 fixation. These results demonstrate that in rice\uffe2\uff80\uff93rice cropping systems biological N fixation plays a vital role in replenishing the soil N pool. However, continuous application of green manure N (GM\uffe2\uff80\uff90N) did not increase crop N availability, perhaps because of the presence of a recalcitrant soil organic matter fraction. Residual effects on rice grain yield and N uptake were observed only with GM\uffe2\uff80\uff90N sources.

Soil surveys with line-scanning platforms appear to have great advantages over the traditional methods used to collect soil information for the development of field-scale soil mapping and applications. These carry VNIR (visible and near infrared) spectrometers and have been used in recent years extensively for the assessment of soil fertility at the field scale, and the delineation of site-specific management zones (MZ). A challenging feature of VNIR applications in precision agriculture (PA) is the massiveness of the derived datasets that contain point predictions of soil properties, and the interpolation techniques involved in incorporating these data into site-specific management plans. In this study, fixed-rank kriging (FRK) geostatistical interpolation, which is a flexible, non-stationary spatial interpolation method especially suited to handling huge datasets, was applied to massive VNIR soil scanner data for the production of useful, smooth interpolated maps, appropriate for the delineation of site-specific MZ maps. Moreover, auxiliary Sentinel-2 data-based biophysical parameters NDVI (normalized difference vegetation index) and fAPAR (fraction of photosynthetically active radiation absorbed by the canopy) were included as covariates to improve the filtering performance of the interpolator and the ability to generate uniform patterns of spatial variation from which it is easier to receive a meaningful interpretation in PA applications. Results from the VNIR prediction dataset obtained from a pivot-irrigated field in Albacete, southeastern Spain, during 2019, have shown that FRK variants outperform ordinary kriging in terms of filtering capacity, by doubling the noise removal metrics while keeping the computation cost reasonably low. Such features, along with the capacity to handle a large volume of spatial information, nominate the method as ideal for PA applications with massive proximal and remote sensing datasets.

Sustainability transitions in agriculture are explored through an analysis of niche initiatives within a common production system, relying on sustainable transitions, multi-level perspectives, and agroecological frameworks, and involving multi-actor, agricultural knowledge, and innovation systems (AKIS). The article focuses on how experimental niches and sustainable activities affect farmers\u2019 relationships with nature, and the reconceptualisation of the production system in which they operate, particularly where this system is embedded in less sustainable conventional or dominant regimes and landscapes. The need for fundamental changes, in the way that humans interact with nature, is widely argued for in order to achieve sustainable development, and farmers occupy a central role through participation in complex networks of agri-food systems. They have also found themselves disconnected from nature through conventional agri-industrial production practices. Four niches (biological control, ecological restoration, soil health, and ecological pond management) within the greenhouse sector of Almeria (SE Spain) are explored in a case study. Our results indicate that a farmer\u2019s interaction with nature is functional, but through agroecological practices, a deeper understanding of the ecosystems in which greenhouse landscapes are embedded may be gained. As they become more connected to nature and benefit from ecosystem services, they can transition to more sustainable agricultural systems.

Changes in agricultural management can potentially increase the accumulation rate of soil organic C (SOC), thereby sequestering CO2 from the atmosphere. This study was conducted to quantify potential soil C sequestration rates for different crops in response to decreasing tillage intensity or enhancing rotation complexity, and to estimate the duration of time over which sequestration may occur. Analyses of C sequestration rates were completed using a global database of 67 long\uffe2\uff80\uff90term agricultural experiments, consisting of 276 paired treatments. Results indicate, on average, that a change from conventional tillage (CT) to no\uffe2\uff80\uff90till (NT) can sequester 57 \uffc2\uffb1 14 g C m\uffe2\uff88\uff922 yr\uffe2\uff88\uff921, excluding wheat (Triticum aestivum L.)\uffe2\uff80\uff90fallow systems which may not result in SOC accumulation with a change from CT to NT. Enhancing rotation complexity can sequester an average 20 \uffc2\uffb1 12 g C m\uffe2\uff88\uff922 yr\uffe2\uff88\uff921, excluding a change from continuous corn (Zea mays L.) to corn\uffe2\uff80\uff90soybean (Glycine max L.) which may not result in a significant accumulation of SOC. Carbon sequestration rates, with a change from CT to NT, can be expected to peak in 5 to 10 yr with SOC reaching a new equilibrium in 15 to 20 yr. Following initiation of an enhancement in rotation complexity, SOC may reach a new equilibrium in approximately 40 to 60 yr. Carbon sequestration rates, estimated for a number of individual crops and crop rotations in this study, can be used in spatial modeling analyses to more accurately predict regional, national, and global C sequestration potentials.

Flavonoids are a broad class of secondary metabolites with multifaceted functionalities for plant homeostasis and are involved in facing both biotic and abiotic stresses to sustain plant growth and health. Furthermore, they were discovered as mediators of plant networking with the surrounding environment, showing a surprising ability to perform as signaling compounds for a multitrophic inter-kingdom level of communication that influences the plant host at the phytobiome scale. Flavonoids orchestrate plant-neighboring plant allelopathic interactions, recruit beneficial bacteria and mycorrhizal fungi, counteract pathogen outbreak, influence soil microbiome and affect plant physiology to improve its resilience to fluctuating environmental conditions. This review focuses on the diversified spectrum of flavonoid functions in plants under a variety of stresses in the modulation of plant morphogenesis in response to environmental clues, as well as their role as inter-kingdom signaling molecules with micro- and macroorganisms. Regarding the latter, the review addresses flavonoids as key phytochemicals in the human diet, considering their abundance in fruits and edible plants. Recent evidence highlights their role as nutraceuticals, probiotics and as promising new drugs for the treatment of several pathologies.

Understanding the effects of diet on enteric methane production can help refine GHG emission inventories and identify viable GHG reduction strategies. Our study focused on measuring methane and carbon dioxide emissions, total-tract digestibility, and ruminal fermentation in growing beef cattle fed a diet supplemented with various additives or ingredients. Two experiments, each designed as a 4 x 4 Latin square with 21-d periods, were conducted using 16 Holstein steers (initial BW 311.6 +/- 12.3 kg). In Exp. 1, treatments were control (no additive), monensin (Rumensin, Elanco Animal Health, Indianapolis, IN; 33 mg/kg DM), sunflower oil (400 g/d, approximately 5% of DMI), and proteolytic enzyme (Protex 6-L, Genencor Int., Inc., CA; 1 mL/kg DM). In Exp. 2, treatments were control (no additive), Procreatin-7 yeast (Prince Agri Products, Inc., Quincy, IL; 4 g/d), Levucell SC yeast (Lallemand, Inc., Rexdale, Ontario, Canada; 1 g/d), and fumaric acid (Bartek Ingredients Inc., Stoney Creek, Ontario, Canada; 80 g/d). The basal diet consisted of 75% barley silage, 19% steam-rolled barley grain, and 6% supplement (DM basis). Four large chambers (two animals per chamber) were equipped with lasers and infrared gas analyzers to measure methane and carbon dioxide, respectively, for 3 d each period. Total-tract digestibility was determined using chromic oxide. Approximately 6.5% of the GE consumed was lost in the form of methane emissions from animals fed the control diet. In Exp. 1, sunflower oil decreased methane emissions by 22% (P = 0.001) compared with the control, whereas monensin (P = 0.44) and enzyme had no effect (P = 0.82). However, oil decreased (P = 0.03) the total-tract digestibility of NDF by 20%. When CH(4) emissions were corrected for differences in energy intake, the loss of GE to methane was decreased by 21% (P = 0.002) using oil and by 9% (P = 0.09) using monensin. In Exp. 2, Procreatin-7 yeast (P = 0.72), Levucell SC yeast (P = 0.28), and fumaric acid (P = 0.21) had no effect on methane emissions, although emissions as a percentage of GE intake were 3% (non-significant, P = 0.39) less for steers fed Procreatin-7 yeast compared with the control.

Over both wet and dry growing seasons from 1998-2000, zone tillage following underseeded RC produced average corn grain yields (7.23 Mg ha -1 ) that were within 1% of those obtained using conventional tillage (7.33 Mg ha -1 ), and 36% higher than those obtained using no tillage and RC (5.33 Mg ha -1 ). Zone tillage also improved soil quality as evidenced by generally lower soil strength than no tillage, and near-surface soil physical quality parameters that were equivalent to, or more favorable than, those of the other treatments. It was concluded that corn production using zone tillage and RC underseeding is a viable option in Brookston clay loam soil, as it retains much of the soil quality benefit of conventional tillage but still achieves most of the yield benefit of conventional moldboard plow tillage.", "keywords": ["2.

The development of second\uffe2\uff80\uff90growth forest after abandonment of agricultural fields in tropical montane cloud forest (TMCF) areas is common in southern Mexico, but little is known about how such changes affect soil properties. We evaluated the changes in soil properties at the 0\uffe2\uff80\uff90 to 20\uffe2\uff80\uff90 and 20\uffe2\uff80\uff90 to 40\uffe2\uff80\uff90cm depths during this conversion in three chronosequences, each composed of a cornfield, and adjacent forests of \uffe2\uff89\uff8815, \uffe2\uff89\uff8845, \uffe2\uff89\uff8875, and \uffe2\uff89\uffa5 100 yr after abandonment at El Rinc\uffc3\uffb3n, Oaxaca, Mexico. All studied soils were acidic, rich in organic C and total nitrogen (TN), and had low levels of plant\uffe2\uff80\uff90available P, exchangeable Ca, Mg, Na, and K, and high levels of exchangeable Al. Most of the soil properties analyzed changed significantly with the age after abandonment, but in most cases the patterns of response varied with the chronosequence, usually \uffe2\uff89\uff8815 to 45 yr after abandonment. In all chronosequences, soil pH and N/P ratio decreased, and the thickness of the O horizon increased, during the first 100 yr of forest development. The highest rates of soil C sequestration and the highest drop in exchangeable K, Mg, and Ca concentrations took place the first 15 yr of forest development. Most of soil changes can be associated with nutrient retention by vegetation and litter, the concentration of exchangeable Al in soil, and the role of soil pH in mineralization rates, ion solubility, and rock weathering.

At high feed intake levels, the proportion of energy lost as CH(4) decreases as the digestibility of the diet increases.

A zero-grazing experiment was conducted to determine the effect of sward DM digestibility (DMD) on DMI, CH(4) emissions, and indices of rumen fermentation of beef animals. Twelve Charolais-cross heifers were assigned to 1 of 2 treatments, with 6 heifers per dietary treatment. Additionally, 4 cannulated Aberdeen Angus-cross steers were randomly allocated to each of these 2 treatments in a crossover design. Dietary treatments consisted of swards managed to produce (i) high digestibility pasture (high DMD) or (ii) pasture with less digestibility (low DMD), both offered for ad libitum intake. All animals were zero-grazed and offered freshly cut herbage twice daily. In vitro DMD values for the high and low DMD swards were 816 and 706 g/kg of DM.

On a global scale, human activity has increased the atmospheric input of NO\uffe2\uff88\uff923 to many terrestrial ecosystems. Anthropogenic NO\uffe2\uff88\uff923 may be a potent modifier of ecosystem function, especially in temperate forests that are sometimes N limited. However, the impact of chronic N deposition on soil microorganisms is still poorly understood. Nitrate entering Lake States forests is rapidly assimilated by the microbial community and it is subsequently released as NH+4 Because high levels of NH+4 inhibit the activity of lignin\uffe2\uff80\uff90degrading soil fungi, we reasoned that chronic N additions could alter the composition and function of heterotrophic microbial communities in soil, and hence the ecosystem\uffe2\uff80\uff90level processes they mediate. We tested our hypothesis in four northern hardwood ecosystems in northern Michigan, which received experimental N additions (30 kg NO\uffe2\uff88\uff923\uffe2\uff80\uff93N ha\uffe2\uff88\uff921 yr\uffe2\uff88\uff921) during the past 8 yr. We quantified microbial community function by measuring the activity of extracellular enzymes involved in plant litter degradation and described microbial community composition using phospholipid fatty acid (PLFA) analysis. Chronic N additions significantly suppressed \uffce\uffb2\uffe2\uff80\uff90glucosidase activity by 24% in mineral soil and suppressed phenol oxidase activity by 35% in surface litter. We found no evidence that chronic N additions altered microbial community composition; NO\uffe2\uff88\uff923 addition did not alter the relative abundance of bacterial, actinomycetal, fungal, or protozoan PLFAs. However, NO\uffe2\uff88\uff923 additions significantly reduced microbial biomass by 18% relative to the control treatment. Results indicate that N additions broadly suppressed all microbial groups, not just the activity and abundance of lignin\uffe2\uff80\uff90degrading fungi.

We measured soil changes through a full rotation of a Eucalyptus saligna (Sm.) plantation. We hypothesized that accretion of C from Eucalyptus trees (C3\uffe2\uff80\uff93derived carbon, C3\uffe2\uff80\uff93C) would be balanced by an equal loss of older soil C derived from sugarcane (Saccharum officinarum L.) agriculture (C4\uffe2\uff80\uff93derived C, C4\uffe2\uff80\uff93C). We also hypothesized that large additions of N\uffe2\uff80\uff90containing fertilizer would increase C accretion by increasing the rate of C addition and decreasing the rate of C loss. The low spatial variability of the soil and the intensive sampling design provided precise tests of these hypotheses. Soil C averaged 13.8 kg m\uffe2\uff88\uff922 for the O horizon plus the 0\uffe2\uff80\uff90 to 45\uffe2\uff80\uff90cm depth mineral soil, with no change through the rotation [95% confidence interval (CI) \uffc2\uffb10.057 kg m\uffe2\uff88\uff922 yr\uffe2\uff88\uff921], supporting the first hypothesis. Significant gains of C3\uffe2\uff80\uff93C (0.136 kg m\uffe2\uff88\uff922 yr\uffe2\uff88\uff921) balanced the losses of C4\uffe2\uff80\uff93C (0.144 kg m\uffe2\uff88\uff922 yr\uffe2\uff88\uff921). The second hypothesis was tested in the field using three levels of repeated, complete fertilization (including N at rates of 300, 700, and 1600 kg N ha\uffe2\uff88\uff921), and in laboratory incubations with N addition. Addition of N had no effect on the accumulation of soil N and C3\uffe2\uff80\uff93C, nor on the rate of loss of older C4\uffe2\uff80\uff93C, refuting the second hypothesis. This first\uffe2\uff80\uff90rotation forest plantation was not able to increase soil C, even with heavy fertilization. These results contrast markedly from the soil changes under the influence of N\uffe2\uff80\uff90fixing trees, indicating that the effect of N fixation on soil C derives from factors other than N supply.

Abstract. Microbes play an essential role in soil functioning including biogeochemical cycling and soil aggregate formation. Yet, a major challenge is to link microbes to higher trophic levels and assess consequences for soil functioning. Here, we aimed to assess how microbial consumers modify microbial community composition (PLFA markers), as well as C dynamics (microbial\u00a0C use, SOC concentration and CO2 emission) and soil aggregation. We rebuilt two simplified soil consumer\u2013prey systems: a bacterial-based system comprising amoebae (Acanthamoeba castellanii) feeding on a microbial community dominated by the free-living bacterium Pseudomonas fluorescens and a fungal-based system comprising collembolans (Heteromurus nitidus) grazing on a microbial community dominated by the saprotrophic fungus Chaetomium globosum. The amoeba A. castellanii did not affect microbial biomass and composition, but it enhanced the formation of soil aggregates and tended to reduce their stability. Presumably, the dominance of P. fluorescens, able to produce antibiotic toxins in response to the attack by A. castellanii, was the main cause of the unchanged microbial community composition, and the release of bacterial extracellular compounds, such as long-chained polymeric substances or proteases, in reaction to predation was responsible for the changes in soil aggregation as a side effect. In the fungal system, collembolans significantly modified microbial community composition via consumptive and non-consumptive effects including the transport of microbes on the body surface. As expected, fungal biomass promoted soil aggregation and was reduced in the presence of H. nitidus. Remarkably, we also found an unexpected contribution of changes in bacterial community composition to soil aggregation. In both the bacterial and fungal systems, bacterial and fungal communities mainly consumed C from soil organic matter (rather than the litter added). Increased fungal biomass was associated with an increased capture of C from added litter, and the presence of collembolans levelled off this effect. Neither amoebae nor collembolans altered SOC concentrations and CO2 production. Overall, the results demonstrated that trophic interactions are important for achieving a mechanistic understanding of biological contributions to soil aggregation and may occur without major changes in C dynamics and with or without changes in the composition of the microbial community.

Identification of diagnostic soil organic matter (SOM) fractions and the mechanisms controlling their formation and turnover is critical for better understanding of C dynamics in soils. Enhanced microaggregate formation and stabilization of C due to reduced macroaggregate turnover has been proposed as a mechanism promoting C sequestration in no\uffe2\uff80\uff90tillage (NT) compared with conventional tillage (CT) systems in temperate soils dominated by 2:1 clay mineralogy. We evaluated the contribution of macroaggregate\uffe2\uff80\uff90protected microaggregates to total soil organic carbon (SOC) sequestration in NT relative to CT in three soils differing in clay mineralogy: a 2:1 clay\uffe2\uff80\uff90dominated soil (2:1), a soil with mixed clay mineralogy [2:1 and 1:1] and oxides (mixed), and a soil dominated by (1:1) clay minerals and oxides (1:1). Microaggregates (mM) were isolated from macroaggregates from 0\uffe2\uff80\uff90 to 5\uffe2\uff80\uff90 and 5\uffe2\uff80\uff90 to 20\uffe2\uff80\uff90cm soil layers. Particulate organic matter (POM) located within the microaggregates (intra\uffe2\uff80\uff90mM\uffe2\uff80\uff90POM) was separated from POM outside of the microaggregates (inter\uffe2\uff80\uff90mM\uffe2\uff80\uff90POM) and the mineral fraction of the microaggregates (mineral\uffe2\uff80\uff90mM). In all three soils, total SOC as well as microaggregate\uffe2\uff80\uff90associated C (mM\uffe2\uff80\uff90C) was greater with NT compared with CT. Although less than half of the total SOC under NT was associated with the microaggregate fraction, more than 90% of the total difference in SOC between NT and CT was explained by the difference in mM\uffe2\uff80\uff90C in all three soils. Thus, we identified and isolated a fraction that explains almost the entire difference in total SOC between NT and CT across soils characterized by drastically different clay mineralogy.

Soil C dynamics are not only important to both productivity and sustainability of terrestrial ecosystems, but also contribute significantly to global C cycling. Adjacent natural forest (NF), and first (1R) and second rotation (2R) hoop pine (Araucaria cunninghamii Aiton ex A. Cunn.) plantations in southeast Queensland, Australia, were selected to investigate the effects of conversion of NF to hoop pine plantations and forest management (harvesting and site preparation of plantation) on the size and the nature of C pools in surface (0\uffe2\uff80\uff9310 cm) soils using chemical extraction, laboratory incubation and 13C cross\uffe2\uff80\uff90polarization with magic\uffe2\uff80\uff90angle\uffe2\uff80\uff90spinning nuclear magnetic resonance spectroscopy (13C CPMAS NMR). Conversion from NF to hoop pine plantations not only led to the reduction of soil total C (by 19.8%), water\uffe2\uff80\uff90soluble organic C (WSOC) (by 17.7%), CaCl2\uffe2\uff80\uff93extractable organic C (by 38.8%), and hot water\uffe2\uff80\uff90extractable organic C (HWEOC) (by 30.9%) and bioavailability of soil C (as determined by CO2 evolved in the incubation), but also to a change in chemical composition of soil C with lower O\uffe2\uff80\uff90alkyl C and higher alkyl C under the 1R plantation compared with NF. Harvesting and site preparation did not significantly affect total soil C and most labile C pools (except for a decrease in WSOC), but led to a lower signal intensity in the alkyl C spectral region and a decreased alkyl C/O\uffe2\uff80\uff90alkyl C (A/O\uffe2\uff80\uff90A) ratio in the soil under the 2R compared with the 1R plantation. The shifts in the amount and nature of soil C following forest conversion may be attributed to changes in litter inputs, microbial diversity and activity, and the disturbance of soil during harvesting and site preparation.

A companion aerobic laboratory incubation study of field\uffe2\uff80\uff90moist soil was conducted at 28\uffc2\uffb0C during the second year. Vegetation control increased soil temperature by 1.8\uffc2\uffb0C during the growing season. Both vegetation control and fertilization increased field net N mineralization, and there was a strong positive interaction between the treatments. Net nitrification constituted 72% of net N mineralization for the combined treatment, and only 8% of net N mineralization for the other treatments. Seasonal patterns in net N mineralization were poorly correlated with soil temperature and moisture. The field and laboratory studies showed the same seasonal dynamics and magnitude of annual treatment effects on net N mineralization, suggesting other factors (e.g., labile C inputs) may be important in controlling net N mineralization.

High grain production of corn (Zea mays L.) can be maintained by adding inorganic N fertilizer, and also by using crop rotations that include alfalfa (Medicago sativa L.), but the relative impact of these management practices on soil quality is uncertain. We examined the effects on soil of N fertilization rate (0, 90, 180, 270 kg ha\uffe2\uff88\uff921, corn phase only) in four cropping systems: CC, continuous corn; CS, corn\uffe2\uff80\uff93soybean [Glycine max (L.) Merr.]; CCOA, corn\uffe2\uff80\uff93corn\uffe2\uff80\uff93oat (Avena sativa L.)\uffe2\uff80\uff93alfalfa; and corn\uffe2\uff80\uff93oat\uffe2\uff80\uff93alfalfa\uffe2\uff80\uff93alfalfa (COAA). The 23\uffe2\uff80\uff90 and 48\uffe2\uff80\uff90yr\uffe2\uff80\uff90old experimental sites, situated in northeast (Nashua) and north central (Kanawha) Iowa, were in a replicated split\uffe2\uff80\uff90plot design and managed with conventional tillage. At Nashua, we measured available N, potential net N mineralization and microbial biomass C (MBC) throughout the growing season; all were significantly higher in the CCOA system. At both sites, post\uffe2\uff80\uff90harvest N stocks, and soil organic C (SOC) concentrations were significantly higher in systems containing alfalfa. Grain yield was most strongly correlated with soil N properties. At Nashua, N fertilizer additions resulted in significantly lower soil pH (0\uffe2\uff80\uff90 to 15\uffe2\uff80\uff90cm depth) and lower exchangeable Ca, Mg, and K and cation exchange capacity (CEC) in the CC and CCOA systems. In an undisturbed prairie reference site for Nashua, low available N, low pH, and high CEC suggested a strong influence of the vegetation on nutrient cycling. In terms of management of soil fertility, inclusion of alfalfa in the rotation differed fundamentally from addition of N fertilizer because high yield was maintained with fewer adverse effects on soil quality.

Plant species, and their interactions with the environment, determine both the quantity and chemistry of organic matter inputs to soils. Indeed, countless studies have linked the quality of organic matter inputs to litter decomposition rates. However, few studies have examined how variation in the quantity and chemistry of plant inputs, caused by either interspecific differences or changing environmental conditions, influences the dynamics of soil organic matter. We studied the effects of 16 grassland species from 4 functional groups (C3 and C4 grasses, forbs, and legumes) growing under ambient and elevated CO2 (560 ppm) and N inputs (4 g m\uffe2\uff88\uff922 yr\uffe2\uff88\uff921) on soil carbon (C) and nitrogen (N) dynamics after 4 yr in a grassland monoculture experiment in Minnesota, USA. Specifically, we related soil C and N dynamics to variation among species and their responses to the CO2 and N treatments in plant biomass and chemistry of roots, the dominant detrital input in the system. The 16 species caused much larger variation in plant litter inputs and chemistry, as well as soil C and N dynamics, than the CO2 and N treatment. Not surprising, variation in the quantity of plant inputs to soils contributed to up to a two\uffe2\uff80\uff90fold variation in microbial biomass and amount of respired nonlabile soil C. Root N concentration (across species and CO2 and N treatments) was significantly negatively related to decomposition of nonlabile soil C and positively related to net N mineralization. Greater labile C inputs decreased rates of net N mineralization, likely because of greater N immobilization. Thus, of the traits examined, plant productivity, tissue N concentration, and labile C production such as from rhizodeposition were most important in causing variation in soil C and N dynamics among species and in response to altered atmospheric CO2 and N supply.
