The experimental design was a split-plot with four replicates; the main factor was the soil management system, conventional tillage (CT) or no-tillage (NT), while the secondary factor was N fertilisation. At the end of the trial, soil samples were taken from all plots at four depths (from 0 to 20\u00a0cm). In these samples the following were determined: pH, soil organic carbon (SOC), total N, available P, exchangeable K, cation exchange capacity (CEC), electrical conductivity (EC) and water aggregate stability (WAS). Soil compaction was measured during the last three years, after maize harvesting. To study the microarthropod community, soil samples (0\u201310\u00a0cm depth) were taken six times over the four years. Our results show that NT significantly increased SOC (+15.8%), total N (+9.6%), C/N (+5.3%), exchangeable K (+37.1%) and WAS (+64.8%). The stratification ratio for exchangeable K reached 2.15 for NT plots. N fertilisation, on the other hand, had no significant effect on most of the physico-chemical indicators, except for pH, CEC and EC. Soil compaction was significantly higher for NT compared with CT up to a depth of 25\u201330\u00a0cm. During the last year, interesting reductions in soil penetration resistance for NT were measured, up to 300\u2013430\u00a0kPa in the 2.5\u201312.5\u00a0cm layer. As for the microarthropods, Acari were more sensitive to tillage compared with Collembola, and the Wardle  V  index proved to be a good indicator of the response to tillage. N fertilisation with 300\u00a0kg\u00a0N\u00a0ha \u22121  had a negative effect on the total microarthropod abundance. The Shannon diversity index gave fluctuating and significantly different results: over the years results were split alternately between the two tillage systems. The QBS-ar index, calculated for all the four years of the study, ranged between 48 and 72, values typical of intensively cultivated soils. The results obtained suggested that it was not influenced by the tillage system. Therefore, this index seems to be unsuitable for detecting the influence of tillage management and N fertilisation on the microarthropod community.", "keywords": ["Biological indices", "2.

Four N treatment levels (0, 50, 150, 300\u00a0kg\u00a0N\u00a0ha\u22121\u00a0year\u22121) were applied monthly in a Pleioblastus amarus bamboo plantation since November 2007.

However, there is a lack of data concerning GHG emissions from soils amended with biochar derived from manure, and from soils outside tropical and subtropical regions. The objective of this study was to quantify the effect on emissions of carbon dioxide (CO2), nitrous oxide (N2O) and methane (CH4) following the addition, at a rate of 18\u00a0t\u00a0ha\u22121, of two different types of biochar to an Irish tillage soil. A soil column experiment was designed to compare three treatments (n\u00a0=\u00a08): (1) non-amended soil (2) soil mixed with biochar derived from the separated solid fraction of anaerobically digested pig manure and (3) soil mixed with biochar derived from Sitka Spruce (Picea sitchensis). The soil columns were incubated at 10\u00a0\u00b0C and 75% relative humidity, and leached with 80\u00a0mL distilled water, twice per week. Following 10 weeks of incubation, pig manure, equivalent to 170\u00a0kg\u00a0nitrogen\u00a0ha\u22121 and 36\u00a0kg\u00a0phosphorus\u00a0ha\u22121, was applied to half of the columns in each treatment (n\u00a0=\u00a04). Gaseous emissions were analysed for 28 days following manure application. Biochar addition to the soil increased N2O emissions in the pig manure-amended column, most likely as a result of increased denitrification caused by higher water filled pore space and organic carbon (C) contents. Biochar addition to soil also increased CO2 emissions. This was caused by increased rates of C mineralisation in these columns, either due to mineralisation of the labile C added with the biochar, or through increased mineralisation of the soil organic matter.", "keywords": ["2.

The majority of studies have focused on decomposition during the growing season, but winter climate is expected to change dramatically. Furthermore, knowledge of the drivers of organic matter decomposition, such as litter chemical composition, has primarily been tested across the growing season so it is unknown whether these drivers are also important during the winter. Given that the depth of snow cover insulates the sub-nivean climate from the much colder air, it is an important control on winter decomposition and is expected to be influenced by climate change, we experimentally manipulated snow cover to simulate impacts of different winter precipitation scenarios on soil processes. Our results show that despite snow reduction negatively affecting decomposer abundance (by 99%) and bulk soil respiration (by 47%), litter decomposition rates showed little to no response. Furthermore, variation in winter decomposition rates among litter types was unrelated to nutrient status, indicating that our current understanding of drivers of litter decomposition may not hold during winter months. Despite very large reductions in decomposer fauna due to snow removal, litter decomposition rates were not consistently responsive, indicative of decoupled responses of soil organisms and soil processes to winter climate change.

In this study, rice grown under non-flooded, continuously flooded and alternating water regimes was pulse labeled with  13 CO 2  and the incorporation of rhizo-C into specific microbial groups was determined by  13 C in phospholipid fatty acids (PLFAs) at day 2 and 14 after the labeling.  A decreased C released from roots under continuously flooded condition was accompanied with lower total  13 C incorporation into microorganisms compared to the non-flooded and alternating water regimes treatments. Continuous flooding caused a relative increase of  13 C incorporation in Gram positive bacteria (i14:0, i15:0, a15:0, i16:0, i17:0, a17:0). In contrast, Gram negative bacteria (16:1\u03c97c, 18:1\u03c97c, cy17:0, cy 19:0) and fungi (18:2\u03c96, 9c, 18:1\u03c99c) showed greater rhizo-C incorporation coupled with a higher turnover under non-flooded and alternating water regimes treatments. These observations suggest that microbial groups processing rhizo-C differed among rice systems with varying water regimes. In contrast to non-flooded and alternating water regimes, there was little to no temporal  13 C change in most microbial groups under continuous flooding condition between day 2 and 14 after the labeling, which may demonstrate slower microbial processing turnover.

In this study, we assessed the effects of reduced (RT) and conventional tillage (CT) on the microbial central C metabolic network, using soil samples from a 12-year-old field experiment in an Irish winter wheat cropping system. Straw was removed from half of the RT and CT plots after harvest or incorporated into the soil in the other half, resulting in four treatment combinations.

Model outcomes were then used to calculate CUE of the microbial community. Whereas the composite samples differed in CUE, the changes were small, with values ranging between 0.757 and 0.783 across treatments and soil depth.

Soil microbial biomass and enzymes had significantly higher values under native vegetation than in degraded land, while restored land mostly corresponded to native vegetation. Soil microbial biomass, respiratory quotient and enzyme activities were more strongly affected by land degradation than soil chemical properties. Soil microbial properties varied more between seasons and years in highly degraded land than under native vegetation suggesting a buffering effect of the native vegetation on soil microbial processes. However, land degradation effects on soil microbial properties were significant in both seasons. Moreover, our results indicate that the land restoration practice applied here shifted soil microbial community composition as indicated by soil microbial stoichiometry. Our results indicate that land degradation strongly deteriorates soil microbial properties and their stability in time, but that land restoration practices likely are successful in promoting the recovery of some soil microbial functions, even after only four years. However, shifts in soil microbial community composition in restored lands may have significant feedback effects on element cycles.", "keywords": ["2. Zero hunger", "13.

Earthworms, in particular, interact with the physical and chemical protection mechanisms of organic matter, major determinants of carbon storage capacity of soils. Studies of a  Liquidambar styraciflua  forest plantation located at the Oak Ridge National Laboratory (ORNL), which was exposed to elevated CO 2  using free air CO 2  enrichment (FACE), show that a key mechanism facilitating soil carbon gain was the protection from rapid decomposition afforded by soil aggregates. To evaluate the effects of site earthworms with different feeding behaviors on soil aggregate formation and the sources of organic matter stabilizing these aggregates, we conducted a 26-day laboratory incubation experiment using plant and soil materials with differential dual isotopic compositions obtained from different CO 2  and  15 N-labeling treatments at the ORNL-FACE site. We used crushed and sieved ( 13 C\u00a0=\u00a0\u221225.5\u2030; \u03b4 15 N\u00a0=\u00a05.1\u2030) to create four treatments: (I) soil only; (II) soil and plant material; (III) soil, plant material, and the native, endogeic earthworm  Diplocardia  sp.; (IV) soil, plant material, and the European, epi-endogeic earthworm  Lumbricus rubellus .

When conventional urea (U) was applied using mid-row banding (MRB), both N2O and NO2I increased by a factor of about 2 compared to broadcast/incorporated (BI). When polymer-coated urea (PCU) was the N source, MRB placement increased both N2O and NO2I compared to BI only in the wetter of the two years. When urea with microbial inhibitors (IU) was the N source, N2O and NO2I were lowest across both years and were less affected by placement than U or PCU.

Materials and methods  We collected soil samples at a depth of 0\u201320\u00a0cm over six times during two plant growing seasons in 2011 and 2012 on a native Leymus chinensis grassland. At each of the six sampling occasions, soil samples were taken from three pairs of the cattle grazed vs. ungrazed plots. We then determined (1) the soil moisture, pH, total carbon and nitrogen, and mineral N (NH4+ and NO3\u2212) content, (2) the potential rates of N2O production from nitrification (     N    N  2   O      ) and from denitrification (     D    N  2   O       and      D    N  2       ) using the acetylene inhibition method, and (3) the abundance of the amoA (ammonia monooxygenase) gene of ammonia-oxidizing archaea (AOA) and ammonia-oxidizing bacteria (AOB), the narG (nitrate reductase) gene and nosZ (nitrous oxide reductase) gene using quantitative real-time PCR (qPCR). The relationship among the changes in the N2O production potential rates, the abundance of microbial functional groups and the soil environment was analyzed using mix effects modeling and structural equation modeling.    Results and discussion  The AOA, AOB, narG, nosZ genes and the potential N2O production rate all varied significantly with the season (P\u00a0     N    N  2   O       and      D    N  2   O      .  Approximately 80% of the variation in      N    N  2   O       could be explained by the abundance of AOA and AOB genes (P\u00a0     D    N  2        (P\u00a0     D    N  2   O      +N2), but not the      D    N  2   O      . Soil moisture was the best predictor for      D    N  2   O      .    Conclusions  The abundance of amoA and narG genes are good indicators for the potential nitrification and denitrification rates in the meadow steppe grassland. Soil moisture is the most important factor controlling the N2O emission potential in the meadow-steppe grassland. The grassland soils protected from animal grazing or that under a moderate grazing for five years did not show a significant difference in potential N2O emissions. Our results suggest that grazing induced grassland degradation may not necessarily be associated with a reduction in N2O emissions as reported in other semiarid grasslands in a more arid environment.", "keywords": ["2.

We determined that 4.3% of the initial PyOM-C was mineralized after 158 days. Moreover, PyOM induced a strongly positive priming effect within the first 18 days; a negative priming effect was observed from Days 18 to 158. The initial increase in organic matter mineralization corresponded to a higher gross N mineralization and NH 4  +  content in the PyOM-treated soil than in the untreated soil.

Seven biochar types were used, which were produced from four different feedstocks pyrolyzed at various temperatures.

Biochar was added to a corn field at rates of 0, 3, 12, 30 tons ha \ufffd 1 three years prior to this study, in comparison to an annual application of 1 t ha \ufffd 1 . Biochar application increased microbial abundance, which nearly doubled at the highest addition rate, while mesofauna activity, and litter decomposition facilitated by mesofauna were not increased signif- icantly but were positively influenced by biochar addition when these responses were modeled, and in the last case directly and positively associated to the higher microbial abundance. In addition, in short- term laboratory experiments after the addition of litter, biochar presence increased NO2 \u00fe NO3 miner- alization, and decreased that of SO4 and Cl. However, those nutrient effects were not shown to be of concern at the field scale, where only some significant increases in SOC, pH, Cl and PO4 were observed.

Compared with P addition, N addition exerted a higher inhibitory effect on SOC mineralization induced by leaf-litter addition. Leaf-litter addition stimulated soil microbial activity and decreased the ratio of bacteria to fungi as a result of greater promotion on fungal growth. Moreover, 16:0 and 18:1\u03c99c phospholipid fatty acids (PLFAs) had greater amount of 13C incorporation than other PLFAs, especially in nutrient-addition treatments. These results suggested that increased C input through leaf litter can stimulate SOC mineralization, whereas atmospheric N and P deposition can reduce this stimulatory effect and promote soil C storage in subtropical forests.

However, it is not clear which trophic levels benefit the most from higher productivity or are the most impacted by disturbance. The density-body mass (DBM) relationship has been shown to reflect changes in the structure of communities subjected to environmental modifications, so far, mainly in aquatic systems. We tested how different seawater inundation frequencies and cattle grazing, which both disturbed and impacted the productivity of a terrestrial system, a salt marsh, affected the size structure of soil fauna communities, expressed by their DBM relationship. We hypothesized that either: (1) all the trophic levels of soil fauna would benefit from higher productivity (i.e., amount of litter mass), reflected by a higher Y-intercept of the DBM relationship; (2) only smaller animals would benefit, reflected by a lower slope of the relationship; (3) or only larger animals would benefit, reflected by a higher slope of the relationship. We collected a large range of soil fauna from different elevation levels in grazed and ungrazed areas, thence subjected to different levels of productivity, represented by litter mass, with the most inundated and grazed area as the least productive one. Considering that pore size must be smaller in inundated and grazed areas, productivity seemed to be a greater factor influencing species distribution than soil structure. We found slopes lower than-0.75, showing that large animals dominated the community. However, a difference between the DBM relationships of the most and least frequently inundated ungrazed sites indicated that higher productivity benefited the smaller animals. Our findings show that high productivity does not equally affect the different trophic levels of this soil fauna community, suggesting inefficient transfers of energy from one trophic level to another, as smaller species benefitted more from higher productivity. \u00a9 2014 Elsevier Ltd.", "keywords": ["population-density", "0106 biological sciences", "abundance", "plant-species richness", "rain-forest", "size relationships", "energetic equivalence rule", "intermediate disturbance hypothesis", "15.

Microbial community structure (based on PLFA composition) and functions (based on enzyme activities and on microbial growth parameters) revealed mechanisms and drivers of priming effects (PE) induced by cellulose addition.   14 C-cellulose input caused negative PE within the first week and was accompanied by fast consumption of unlabelled DOC and its incorporation into microbial biomass. Microbial activation however, was not confirmed by substrate-induced respiration, nor by hydrolytic enzymes activity or by PLFA changes. A remarkable exception was a 2-fold increase in protozoan PLFA. Such an increase indicates that microorganisms feeding on cellulose and on DOC were quickly grazed by protozoans acting as a driver of microbial succession. This experimentally demonstrates the functioning of the microbial interactions: protozoan grazers provided for rapid recycling of nutrients and facilitated the succession of cellulose-degrading microorganisms during the second week of cellulose decomposition. An increase in the activity of cellulolytic enzymes caused short-term real PE accompanied by increase in abundance of slow-growing fungi and G(\u2212) bacteria. Long-term real PE observed between 14 and 60 days after cellulose input was due to decomposition of SOM-originated hemicelluloses by fungi and G(+) bacteria. The CO 2  released by primed soil organic matter (SOM) decomposition was originated mainly from C younger than 12 years (63%) and only 37% were older than 12 years despite the recent and old C contributed almost equally (51 and 49%, respectively) to SOM under  Miscanthus giganteus . This indicates that the SOM pools are involved in PE according to their availability. Despite 71% of the applied cellulose-C was sequestered in the soil, the net soil C-gain amounted only for 28% of the applied cellulose-C after factoring in the C losses by the PE. Our study emphasizes the role of food webs in the PE dynamics: cellulose input served as a driver activating the food chain through the microbial loop.", "keywords": ["2.

Increases in soil C in litter addition treatments were less than C losses from litter exclusion treatments, with surface C increasing by 12% in DL and 6% in DW. Detritus additions and removals had significant effects on soil microclimate, with decreases in seasonal variations in soil temperature (between summer and winter) in Double Litter plots but enhanced seasonal variation in detritus exclusion plots. Carbon dioxide (CO2) emissions were most influenced by detritus input quantity and soil organic matter concentration when soils were warm and moist.

Net N mineralization and nitrification rates were investigated via incubations of sieved soils transplanted from ten temperate forest ecosystems to two northern Japan sites with natural snowfall gradients. This was done to address: 1) how freeze\u2013thaw cycles affect N mineralization and nitrification in temperate forest soils; 2) whether freeze\u2013thaw cycles change the soil N transformation rates in the following growing season; and 3) which soil characteristics affect the response of the N transformation rates to freeze\u2013thaw cycles. The effect of freeze\u2013thaw cycles on inorganic N and dissolved organic carbon productions differed among soils, that is, some soils produced more inorganic N and dissolved organic carbon in the conditions imposed by freeze thaw cycles than in the non-frozen treatment but the others did not. The response to the freeze\u2013thaw cycles was explained by soil microbial activity (gross N mineralization and nitrification rate) and soil fertility (inorganic N pools in the early spring and water soluble ions). Freeze\u2013thaw cycles significantly increased N transformation rates in the following growing season, suggesting that winter climate change might also affect nutrient availability for vegetation and soil microbes in the growing season. The magnitude and frequency of freeze\u2013thaw cycles were considered to be important indicators of N transformation rates during the growing season, suggesting that the higher intensity of freeze\u2013thaw cycles in the original locations of soils changed the microbial communities and functions with high tolerance to freeze\u2013thaw cycles; this resulted in greater N transformation rates in the following growing season.

The aim of this study was to test the hypothesis that intercropping could promote P cycling, through microbial biomass P (MBP) changes, in a field trial in a Mediterranean climate. Changes in microbial biomass carbon (MBC), MBP, and inorganic P availability in the rhizosphere of intercropped species were thus investigated in durum wheat/chickpea and durum wheat/lentil intercrops and compared to the bulk soils as well as the rhizosphere of each species grown alone. When expressed relative to the bulk soil, MBC increased in the rhizosphere only for the intercropped plants, irrespective of species. Relative to MBC in the rhizosphere of sole crops, MBC increased in the rhizosphere of the two legume species when intercropped with durum wheat, while no such effect was found for durum wheat. We were unable to detect an increase in P availability in the rhizosphere as a response to intercropping in any of the three crop species, but there was a systematic increase in available P in the rhizosphere relative to the corresponding bulk soil. Fairly similar patterns were observed for MBP as for MBC, except within the rhizosphere of durum wheat when intercropped with chickpea: relative to the bulk soil, MBP increased in the rhizosphere of both lentil and chickpea when intercropped with durum wheat as well as in the rhizosphere of durum wheat when intercropped with chickpea. The differences in microbial biomass changes for a given cereal (durum wheat) when intercropped with two different legumes, suggest that plants have strong species-specific influences on each other as well as on the soil environment. The molar ratios of MBC to MBP (MM C:P) did not vary significantly except for the rhizosphere of durum wheat intercropped with chickpea, which was fairly low (16:1), about half the values found in the other treatments (26\u201340:1). These MM C:P values were lower than those generally reported in soils (38\u201360:1), verifying the hypothesis that microbes can increase storage of soil P in their biomass, creating stocks of microbial P in the soil when P availability is high. In this Mediterranean climate where surface soils undergo frequent drying-rewetting, known for liberation of microbial biomass, MBP could be an important factor influencing P availability.

Furthermore, soil CO 2  flux \u2013 including plant root and microbial respiration \u2013 is a key feedback to ecosystem carbon (C) cycling that links ecosystem processes to climate, yet few studies have investigated the effects of N enrichment on belowground processes in water-limited ecosystems. In this study, we conducted two-level N addition experiments to investigate the effects of N enrichment on microbial and root respiration in a grassland ecosystem on the Loess Plateau in northwestern China. Two years of high N additions (9.2\u00a0g\u00a0N\u00a0m \u22122 \u00a0y \u22121 ) significantly increased soil CO 2  flux, including both microbial and root respiration, particularly during the warm growing season. Low N additions (2.3\u00a0g\u00a0N\u00a0m \u22122 \u00a0y \u22121 ) increased microbial respiration during the growing season only, but had no significant effects on root respiration. The annual temperature coefficients (Q 10 ) of soil respiration and microbial respiration ranged from 1.86 to 3.00 and 1.86 to 2.72 respectively, and there was a significant decrease in Q 10  between the control and the N treatments during the non-growing season but no difference was found during the growing season. Following nitrogen additions, elevated rates of root respiration were significantly and positively related to root N concentrations and biomass, while elevated rates of microbial respiration were related to soil microbial biomass C (SMBC). The microbial respiration tended to respond more sensitively to N addition, while the root respiration did not have similar response. The different mechanisms of N addition impacts on soil respiration and its components and their sensitivity to temperature identified in this study may facilitate the simulation and prediction of C cycling and storage in semiarid grasslands under future scenarios of global change.", "keywords": ["2.

However, the effect of biochar application on the decomposition of soil organic C (SOC) as well as its mechanisms is not well understood in the sandy loam soil of North China Plain. We investigated how biochar affected the decomposition of native SOC, using stable \u03b413C isotope analyses by applying biochar produced from corn straw (a C4 plant, \u03b413C\u00a0=\u00a0\u221211.9\u2030) to a sandy loam soil (\u03b413C of SOC\u00a0=\u00a0\u221224.5\u2030) under a long-term C3 crop rotation.

Compared with Control, N amendment significantly (P\u00a0<\u00a00.05) increased total soil CO2 emission, even when combined with biochar amendment.

N addition immediately stimulated the growth of microorganisms and altered microbial community structure by increasing Gram-positive bacteria compared to Control as measured by phospholipid fatty acid. Biochar amendment did not alter microbial biomass during the 720-h incubation period except at 168 and 720\u00a0h, but significantly (P\u00a0<\u00a00.05) lowered dissolved organic C (DOC) content in soil, primarily due to sorption of DOC by the biochar.

To assess whether and at what rate C accumulates in the soil of young mangrove forests following afforestation, we conducted a field study at an afforestation project in southeast China, including repeated measures taken over six years at two young forests (consisting of  Kandelia obovata  and  Sonneratia apetala , aged 0\u20136 years old), and also a chronosequence of forests aged 0 (mudflat), 6 (both species), 20 ( S.\u00a0apetala ), and 70 ( K.\u00a0obovata ) years old. In the repeated measures, surface (0\u201310\u00a0cm) soil C concentration (%C of dry soil mass) increased significantly over six years, from 1.14% to 1.52% ( K.\u00a0obovata ) and 1.23% to 1.68% ( S.\u00a0apetala ).

Yet, we do not have a thorough understanding of how biochemical composition of soil microbial biomass is related to carbon turnover and persistence of different microbial components. Using a suite of state-of-the-art analytical techniques, we investigated the molecular characteristics of extractable microbial biomass and linked it to its carbon turnover time. A 13CO2 plant pulse labelling experiment was used to trace plant carbon into rhizosphere soil microbial biomass, which was obtained by chloroform fumigation extraction (CFE). 13C content in molecular size classes of extracted microbial compounds was analysed using size exclusion chromatography (SEC) coupled online to high performance liquid chromatography\u2013isotope ratio mass spectrometry (SEC-HPLC-IRMS). Molecular characterization of microbial compounds was performed using complementary approaches, namely SEC-HPLC coupled to Fourier transform infrared spectroscopy (SEC-HPLC-FTIR) and electrospray ionization Fourier transform ion cyclotron resonance mass spectrometry (ESI-FT-ICR-MS). SEC-HPLC-FTIR suggests that mid to high molecular weight (MW) microbial compounds were richer in aliphatic CH bonds, carbohydrate-like compounds and possibly Pdouble bond; length as m-dashO derivatives from phospholipids. On the contrary, the lower size range was characterized by more oxidised compounds with hydroxyl, carbonyl, ether and/or carboxyl groups. ESI-FT-ICR-MS suggests that microbial compounds were largely aliphatic and richer in N than the background detrital material. Both molecular characterization tools suggest that CFE derived microbial biomass was largely lipid, carbohydrate and protein derived. SEC-HPLC-IRMS analysis revealed that 13C enrichment decreased with increasing MW of microbial compounds and the turnover time was deduced as 12.8 \u00b1 0.6, 18.5 \u00b1 0.6 and 22.9 \u00b1 0.7 days for low, mid and high MW size classes, respectively. We conclude that low MW compounds represent the rapidly turned-over metabolite fraction of extractable soil microbial biomass consisting of organic acids, alcohols, amino acids and sugars; whereas, larger structural compounds are part of the cell envelope (likely membrane lipids, proteins or polysaccharides) with a much lower renewal rate. This relation of microbial carbon turnover to its molecular size, structure and composition thus highlights the significance of cellular biochemistry in determining the microbial contribution to soil carbon cycling and specifically soil organic matter formation.", "keywords": ["2.

Although this relationship has been widely contested, it is rarely tested for soil invertebrate fauna, an important component of terrestrial biodiversity. We tested disturbance-diversity relationships for soil meso- and macrofauna in a salt marsh where periodic sea water inundation and cattle grazing occur as stressors. We hypothesized a unimodal inundation frequency-diversity relationship, whereas we expected grazing to overrule the effects of inundation frequency due to its large effects on the habitat of soil fauna. We found a negative relationship between inundation frequency and diversity at the ungrazed sites and no relationship at the grazed sites. Moreover, we found a negative relationship between community biomass and diversity for soil fauna that may have caused this negative disturbance-diversity relationship. Community biomass at the intermediate inundation frequency increased due to the dominance of Orchestia gammarellus (a macro-detritivore species), which could exploit low quality litters at the ungrazed sites.

Recent reviews have found a positive effect of increased N inputs on C stabilization in soils of temperate forest ecosystems. However, there is still uncertainty about the role and magnitude of the effect of chronic N inputs on forest soil C sequestration and how different tree species can modulate this effect. We evaluated the response of soil C lability to experimental N additions across plots with different dominant tree species (Acer saccharum, Fagus grandifolia, Betula alleghaniensis, Tsuga canadensis and Quercus rubra). We used a 14-year N addition experiment with a single-species, paired-plot design, and several measurements to estimate C lability, including soil laboratory incubations and density fractionation. Our two principal measures of C lability showed statistically significant interactive effects of N treatment and tree species composition: soils from maple (Acer) stands showed the greatest effect of added N on the light fraction mass in the mineral horizon (a 69% increase), and soils from beech (Fagus) stands showed the greatest N effect on potentially mineralizable C (a 23% decrease). Decreases in soil decomposition and respiration rates in organic and mineral horizons in response to N addition across all five species suggest a significant suppression of C mineralization, particularly in the first few weeks of the incubation, with the strongest responses in beech and oak (Quercus) stands. Our results confirm that increased N additions significantly reduce soil organic matter decomposition rates and the lability of soil C for some tree species, and indicate that mechanisms other than organo-mineral associations could play an important role in the stabilization of C in these soils. Further, our research illustrates the need to consider varying responses among different tree species when predicting future consequences of N inputs on soil C storage.", "keywords": ["2.

We investigated the abundance and major populations of ammonia-oxidizing archaea (AOA) and bacteria (AOB), and nirS- and nirK-harboring denitrifiers under different grazing managements in Tibetan alpine meadow soils. Grazing increased AOB and AOA abundances up to 42 fold and 3.7 fold, respectively, and increased the percentage of AOB within total ammonia oxidizers from 3.1% to 10.8%. The abundance of nirK-like denitrifiers increased with grazing intensity, while the abundance of nirS-like denitrifiers tended to decrease. However, sub-groups within each of these broad groups of (de)nitrifiers responded differently to grazing. Soil nitrate was the main driver of the abundance of denitrifier subgroups (nirK or nirS) positively responding to grazing, while soil moisture and carbon concentration were the main drivers of the abundance of denitrifier sub-groups negatively responding to grazing. AOB and nirK-harboring denitrifiers thus generally responded more positively to grazing than AOA and nirS-harboring denitrifiers, but significant functional diversity existed within each group.

One control mechanism is the priming effect (PE) which consists in stimulating SOM mineralization with the addition of fresh, energetic plant material. In this study, we quantified C mineralization and PE in soils sampled in two contrasted long-term (40 years) tillage treatments which deeply modified soil properties (e.g. organic C concentration, microbial biomass, pH). We hypothesized that soil tillage might affect these processes through changes in C addition rates, nutrient availability, and long-term variations in SOM content and microbial communities. We investigated the relationship between PE intensity, tillage and nutrients availability in soil samples taken in no till (NT) and full inversion tillage (FIT) in two layers (0\u20135 and 15\u201320\u00a0cm). Soils were incubated with or without addition of  13 C labeled cellulose and mineral nutrients. Potential C mineralization and primed C were measured during 262 days. Unlabeled soil microbial biomass C was determined at the end of the experiment to separate apparent and real priming effect.  Basal cumulative C mineralization in the control soil ranged from 363 to 1490\u00a0mg\u00a0kg \u22121  soil at day 262. It was strongly correlated with soil organic carbon (SOC) concentration. Specific mineralization rates were 44.8 and 68.8\u00a0g\u00a0kg \u22121  SOC in the 0\u20135\u00a0cm layer for the FIT and NT treatments, respectively and were strongly linked with the particulate organic matter content ( r \u00a0=\u00a00.99***). These results suggest that SOC was more active in the upper layer of the NT treatment due to the high concentration of readily-decomposable, particulate organic matter. The cellulose was entirely metabolized after 60 days and its kinetics of mineralization was affected neither by tillage, depth nor nutrients. The percentage of cellulose C released as CO 2  represented 55\u201361% of the added cellulose-C at day 262. A positive PE was found in all treatments and its kinetics was parallel to that of cellulose mineralization. The cumulative PE significantly varied with nutrients level but not tillage, ranging from 73 to 78\u00a0mg\u00a0kg \u22121  under high nutrients level and from 116 to 136\u00a0mg\u00a0kg \u22121  in low nutrients level. No significant differences were found in unlabeled microbial biomass C between control and amended soil, suggesting no apparent priming effect. We conclude that the priming was mainly controlled by nutrient availability but not tillage, in spite of strong tillage-induced changes in SOC concentration and microbial biomass. Since PE is known to depend on C addition rate, tillage is expected to affect  in situ  PE through variations in the ratio of fresh carbon to nutrient concentration along the soil profile.", "keywords": ["priming effect", "2.

Our objective was to examine how temporal plant diversity (i.e. crop rotation) influences residue decomposition, a key ecosystem function that regulates nutrient cycling, greenhouse gas emissions, and soil organic matter formation. We incubated soils from five long-term crop rotations, located at W.K. Kellogg Biological Station LTER in southwestern Michigan, USA, with and without four chemically diverse crop residues. Increasing crop biodiversity increased soil potentially mineralizable C by 125%, increased hydrolytic enzyme activity by 46%, but decreased oxidative enzyme activity by 20% in soils before residue was added. After residue additions, soils from more diverse cropping systems decomposed all residues more rapidly (0.2e8.3% greater mass loss) compared to monoculture corn. The fast-cycling, \u2018Active C\u2019 pool and microbial biomass N increased with higher cropping diversity, but the differences among rotations in Active C pools was higher for the most recalcitrant residues. Further, the ratio of the cellulose degrading enzyme ( b-glucosidase) to the lignin degrading enzyme (phenol oxidase) was highest in the two most diverse crop rotations regardless of residue additions, providing additional evidence of enhanced microbial activity and substrate acquisition in more diverse rotations. Our study shows that crop diversity over time influences the processing of newly-added residues, microbial dynamics, and nutrient cycling.

Microorganisms, when stimulated by the presence of new inputs of labile organic carbon, can mineralize (\u2018prime\u2019) soil organic matter to acquire nutrients. We used stable carbon isotopes to assess how nutrient demand and soil properties constrain mineralization of added labile (sucrose) carbon and pre-existing (primed) soil carbon in tropical forest soils. In a series of lowland tropical forest soils from Panama, we found that the mineralization of fresh labile carbon was accelerated foremost by phosphorus addition, whereas the mineralization of pre-existing soil carbon was constrained foremost by nitrogen addition. However, there was variation in the relative importance of these nutrients in different soils and the largest effects on the acceleration of sucrose metabolism and constraint of priming occurred following the addition of nitrogen and phosphorus together. The respiration responses due to sucrose or primed soil carbon mineralization were reduced at pH below 4.8 and above 6.0. We conclude that in these tropical forest soils, phosphorus availability is more important in promoting microbial mineralization of sucrose carbon, whereas nitrogen availability is more important in constraining the priming of pre-existing soil organic carbon. This response likely arises because nitrogen is more closely coupled to organic matter cycling, whereas phosphorus is abundant in both organic and inorganic forms. These results suggest that the greatest impact of priming on soil carbon stocks will occur in moderately acidic tropical forest soils of low nitrogen availability. Given long-term changes in both atmospheric carbon dioxide and nitrogen deposition, the impact of priming effects on soil carbon in tropical forest soils may be partially constrained by the abundance of nitrogen.", "keywords": ["2.

To achieve this objective, five different enzymatic activities, TOC, water soluble carbon and microbial biomass carbon were measured on soil samples collected at an experimental farm situated in the southwest region of Spain. Furthermore, the relative abundance of organic compound classes was measured, using CPMAS 13C NMR on bulk soil samples, humic acids (HA), and particulate organic matter (POM) fractions separated by density. Our results show that conservation tillage enhances soil quality at the surface for mid- and long-term experiments. The NMR analyses demonstrate that conservation tillage led to a preservation of less degraded SOM and revealed a high amount of proteinaceous material preserved from degradation. It is clear that TOC, \u03b2-glucosidase and alkaline phosphatase activities are reliable soil quality indices and we further propose that the CPMAS 13C NMR analyses of the particulate organic matter (POM) fraction of soil is an excellent evaluator for changes that occur in soil status.", "keywords": ["2.

Multi-year experiments, spanning beyond initial degradation of biologically labile biochar constituents, on the other hand are more scarce, although these are much needed to establish the medium-term effect of biochar on soil organisms. In the present study, soil was sampled from biochar-amended and control plots of four biochar field trials at Lincoln (UK), Rivignano, Rocca Bernarda and Beano in Italy. Air-dried pre-incubated soil samples were incubated at 15 \u00b0C for 8\u20139 weeks to follow-up carbon dioxide (CO2) emissions. We then determined soil \u03b2-glucosidase and dehydrogenase enzyme activity, and used PLFA analysis to quantify the total soil microbial biomass and community structure. The analysis indicated that soil microbial activity was either not affected or inhibited to different extents in the biochar-amended plots. At Lincoln, with the highest application rate (49 t ha\u22121), an overall inhibition of all investigated measures of microbial activity, a lower sum of extracted PLFAs and lower fungal abundance were observed. On the other end at Beano, depth dispersion of biochar by deep tillage and a lower application rate (20 t ha\u22121) probably explain the absence of any significant effect on microbial activity in that experiment. At Rivignano and Rocca Bernarda, dehydrogenase activity was lower in the biochar amended soil and C-mineralization was lower as well for Rivignano. Interestingly, however, \u03b2-glucosidase activity and the sum of extracted PLFAs was not affected by biochar treatment. Several mechanisms could reconcile the different effect of biochar application on overall microbial activity on the one hand and microbial abundance and rate of cellulose degradation on the other. Biochar amendment led to a lowered or equal soil microbial activity and abundance in most field sites. In contrast to many short-term laboratory studies, it therefore seems unlikely that biochar would still function as a substrate 1\u20134 years after incorporation in the field.", "keywords": ["0401 agriculture", " forestry", " and fisheries", "04 agricultural and veterinary sciences", "15.

A clay soil and a sandy soil with equivalent weather and cultivation history were incubated for 142 days at 0, 4, 8.5 or 15\u00a0\u00b0C, which is representative for the natural temperature range above 0\u00a0\u00b0C of these soils. The soils were incubated with or without  13 C labelled clover leaves in gas tight chambers. In absence of added plant litter, the decomposition rate [mol CO 2  (mol\u00a0substrate-C) \u22121 \u00a0day \u22121 ] of SOC followed a first order reaction and it was twice as fast in the sandy soil as in the clay soil. Contrary to our hypothesis, the relative response of SOC mineralisation rate to temperature was the same in both soils; it was well described by an Arrhenius function and it could also be approximated as a linear function of temperature. The mineralisation of clover leaves was affected by soil type, and was slower in the clay than in the sandy soil. Also the initial temperature sensitivity of the clover decomposition (to 18% decomposed) could be approximated by a linear function. SOC mineralisation was enhanced (priming effect) by the presence of clover; the relative increase was most conspicuous at 0\u00a0\u00b0C (150\u2013250% over 142 days, depending on the soil) and decreased with temperature (+40% at 15\u00a0\u00b0C). At the start of the incubation and up to 52 days of incubation the priming effect was correlated with the amount of CO 2  derived from mineralisation of clover leaves. We suggest that the effect of soil type on the diffusivity of enzymes could be an important mechanism affecting the decomposition rate and probably also the volume of soil exposed to priming around decomposing litter.

To examine the influence of grassland degradation and grassland use type changes on gases fluxes, emissions of CO2, CH4 and N2O were measured in three alpine ecosystems (alpine meadow, alpine steppe and alpine desert) with healthy and degraded grasslands on the Qinghai-Tibetan Plateau in May, August and October 2013. The lowest CO2, CH4 and N2O fluxes occurred in alpine deserts, and the highest fluxes occurred in alpine steppe. In general, degraded grasslands had relatively higher gas fluxes than healthy grasslands, except for CH4 dynamics. The temporal variation in gas fluxes indicated that CO2 and N2O fluxes were highest in August and lowest in May, while the lowest fluxes of CH4 were in August. Stepwise linear analysis was employed to explore the key factors for different gas fluxes. In alpine meadow and alpine steppe, the variation in CO2 and N2O fluxes in August could be explained by soil temperature and soil water content, while in May and October, soil physical and chemical properties, including soil pH, clay content and         NO   3    -     \u2013N, were the key factors. Soil water content and         NH   4    +     \u2013N contributed to the CH4 fluxes. However, in alpine desert, soil water content was the key factor affecting gas emissions for different experimental sites.

We anaerobically incubated a highly organic soil with 13C-enriched rice straw for 3 months to investigate its priming effect (PE) on SOM and source of C for CH4 production. Anaerobic decomposition of SOM was accompanied by iron (Fe) reduction with minimal CH4 production when straw was absent. Straw addition enhanced Fe reduction and increased CH4 production concurrently with a clear succession of microbial community structure and function assessed with phospholipid fatty acid (PLFA) profiling. The PE on CH4 production from SOM was strong and positive during the entire experiment. Overall, PE on SOM (CO2 plus CH4 production) was slightly positive at the end of the experiment, associated with only a 32% mineralization of the added straw-C (as CO2 plus CH4). Straw addition also released large amounts of dissolved organic carbon (DOC) from SOM.

The primary aim of  this study was to determine if litter chemistry impacted the decomposition of soil and litter-derived  carbon (C), and its interaction with temperature, and whether this response was controlled by microbial  community structure and function. Fresh or pre-incubated eucalyptus leaf litter (13C enriched) was  added to a woodland soil and incubated at 12, 22, or 32 \ufffdC. We tracked the movement of litter and soilderived  C into CO2, water-extractable organic carbon (WEOC), and microbial phospholipids (PLFA). The  litter additions produced significant changes in every parameter measured, while temperature, interacting  with litter chemistry, predominately affected soil C respiration (priming and temperature sensitivity),  microbial community structure, and the metabolic quotient (a proxy for microbial carbon use  efficiency [CUE]). The direction of priming varied with the litter additions (negative with fresh litter,  positive with pre-incubated litter) and was related to differences in the composition of microbial communities  degrading soil-C, particularly gram-positive and gram-negative bacteria, resulting from litter  addition. Soil-C decomposition in both litter treatments was more temperature sensitive (higher Q10)  than in the soil-only control, and soil-C priming became increasingly positive with temperature. However,  microbes utilizing soil-C in the litter treatments had higher CUE, suggesting the longer-term stability  of soil-C may be increased at higher temperature with litter addition.

We hypothesised that mangrove-produced tannins induce a nitrogen (N) limitation on microbial decomposition even when plant growth is limited by phosphorus (P). As a result, increased N influx would lead to a net loss of sequestered carbon negating the ability to compensate for sea level rise in P-limited mangroves. To examine this, we quantified the short- and long-term effects of N and P enrichment on microbial biomass and decomposition-related enzyme activities in a Rhizophora mangle-dominated mangrove, which had been subjected to fertilisation treatments for a period of fifteen years. We compared microbial biomass, elemental stoichiometry and potential enzyme activity in dwarf and fringe-type R. mangle-dominated sites, where primary production is limited by P or N depending on the proximity to open water. Even in P-limited mangroves, microbial activity was N-limited as indicated by stoichiometry and an increase in enzymic activity upon N amendment. Nevertheless, microbial biomass increased upon field additions of P, indicating that the carbon supply played even a larger role. Furthermore, we found that P amendment suppressed phenol oxidase activity, while N amendment did not. The possible differential nutrient limitations of microbial decomposers versus primary producers implies that the direction of the effect of eutrophication on carbon sequestration is nutrient-specific. In addition, this study shows that phenol oxidase activities in this system decrease through P, possibly strengthening the enzymic latch effect of mangrove tannins. Furthermore, it is argued that the often used division between N-harvesting, P-harvesting, and carbon-harvesting exoenzymes needs to be reconsidered.", "keywords": ["Rhizophora", "Decomposition", "Peat", "Differential nutrient limitation", "04 agricultural and veterinary sciences", "15.

Cover cropping in orchards and symbiotic microbial inoculation are considered to improve soil quality, including P status, however, their effects on the hydrolysis of Po is little known. In this study, five soil managements were established in a guava orchard in South China for two and a half years, including clean culture (CC), cover cropping with  Paspalum natatu  (PN), PN with arbuscular mycorrhizal fungal inoculation (PNA), cover cropping with  Stylosanthes guianensis  (SG), SG with rhizobial inoculation (SGR). Soil chemical, biochemical and microbial properties were analyzed. Results indicate that soil pH and SOM content tended to increase following cover cropping alone or with microbial inoculation. Po content was significantly elevated in PNA. Po fractionation revealed that cover cropping alone or with microbial inoculation significantly affected the contents of moderately labile Po (MLPo) and moderately resistant Po (FAPo). Enzyme assay indicated that cover cropping with microbial inoculation increased the activities of acidic phosphomonoesterase (ACP), neutral phosphomonoesterase (NP) and alkaline phosphomonoesterase (ALP), with ALP the most sensitive, although ACP activity dominated in red soils. Correlation analysis suggested a significantly positive relationship between ALP activity and MLPo or FAPo. PCR-DGGE profile of the  alp -harboring bacterial community showed that cover cropping with  S.\u00a0guianensis  and mycorrhizal inoculation to  P.\u00a0natatu  promoted the bacterial diversity and/or species richness. For almost all the measured parameters, PN and SG were comparable, however, PNA was superior to SGR, indicating the stronger additive effect of arbuscular mycorrhizal fungus than that of rhizobia. Cat-PCA indicated that MLPo was the most influential factor on phosphomonoesterase. In general, this study suggests that, in subtropical orchards with red soil, cover cropping with microbial inoculation can improve the Po hydrolysis via the promoted  alp -harboring bacterial community and then ALP activity.

We then examined whether biochar amendment affected N2O emissions and the availability and transformations of N in soils.    Our results show that biochar suppressed cumulative soil N2O production by 91% in near-saturated, fertilised soils. Cumulative denitrification was reduced by 37%, which accounted for 85\u201395 % of soil N2O emissions.

We concluded that this immobilisation was insignificant compared to total soil inorganic N content. In contrast, soil N mineralisation significantly increased by 269% and nitrification by 34% in biochar-amended soil.    These findings demonstrate that biochar amendment did not limit inorganic N availability to nitrifiers and denitrifiers, therefore limitations in soil NH4+ and NO3\u2212 supply cannot explain the suppression of N2O emissions.

The direction of responses to added nutrients was consistent among sites and between forest ages. We conclude that in these organic horizons limitation by N promotes mineralization of C from SOC, whereas limitation by P constrains mineralization of C from new organic inputs.
