The quantity and/or quality of soil organic matter (SOM) and its fractions regulate microbial community composition and associated function. In this study an established, replicated agricultural systems trial in a semi-arid environment was used to test: (i) whether agricultural systems which have increased plant residue inputs increase the amount of labile SOM relative to total SOM, or change the quality of SOM fractions; and (ii) whether the size or quality of OM fractions is most strongly linked to the size, activity, functional diversity, and community structure of the soil microbial biomass. Soil (0\uffe2\uff80\uff9350\uffe2\uff80\uff89mm) was collected following 5 years of continuous wheat, crop rotation, crop\uffe2\uff80\uff93pasture rotation, annual pasture, or perennial pasture. Pastures were grazed by sheep. Direct drilling and non-inversion tillage techniques were compared in some cropping systems. Total carbon (C) increased with the proportion of pasture as a result of increased SOM inputs into these systems; land use also significantly affected SOM fractions and their chemical and physical nature. While the size, function, and structure of the soil microbial community were somewhat related to total soil C, they were better correlated with SOM fractions. The C\uffe2\uff80\uff89:\uffe2\uff80\uff89nitrogen (N) ratio of light fraction organic matter could be used to predict the amount of potentially mineralisable N in soil, while the C\uffe2\uff80\uff89:\uffe2\uff80\uff89N ratio of total SOM could not. Measurement of bacterial community structure (using denaturing gradient gel electrophoresis) significantly discriminated between land uses, while community-level physiological profiles revealed fewer differences. Overall, our findings support the premise that labile fractions of SOM are more strongly related to microbial community structure and function than is total SOM.

Nine plots were selected, of which three were used as controls, three were burned with low-intensity fire and three with higher intensity fire. N2O fluxes, soil humidity and temperature were measured starting 2 days before burning and for 1 year after fire. Potential net nitrification, denitrification enzyme activity, mineral N and organic C were measured from soil samples collected periodically after burning. Cumulative data indicate a doubling of N2O production in burned plots over 1 year. Burned plots showed an increase of frequency of hot spots of N2O production. A slight detrimental effect of fire on the analysed biological activities was detected only immediately after burning. After 3 months, both potential net nitrification and denitrification enzyme activity had mostly recovered and potential net nitrification further increased over control levels in the following months. Fire seemed to induce a change in the main source of N2O, which in control plots was represented by heterotrophic activity (50\uffe2\uff80\uff9375%), whereas in burned plots it was mostly of autotrophic origin, most probably due to the significant increase of soil NH4+ after burning.

However, it remains unclear if and how N\uffe2\uff80\uff90induced P limitation varies over time. Soil extracellular phosphatases catalyze the hydrolysis of P from soil organic matter, an important adaptive mechanism for ecosystems to cope with N\uffe2\uff80\uff90induced P limitation. Here we show, using a meta\uffe2\uff80\uff90analysis of 140 studies and 668 observations worldwide, that N stimulation of soil phosphatase activity diminishes over time. Whereas short\uffe2\uff80\uff90term N loading (\uffe2\uff89\uffa45\uffc2\uffa0years) significantly increased soil phosphatase activity by 28%, long\uffe2\uff80\uff90term N loading had no significant effect. Nitrogen loading did not affect soil available P and total P content in either short\uffe2\uff80\uff90 or long\uffe2\uff80\uff90term studies. Together, these results suggest that N\uffe2\uff80\uff90induced P limitation in ecosystems is alleviated in the long\uffe2\uff80\uff90term through the initial stimulation of soil phosphatase activity, thereby securing P supply to support plant growth. Our results suggest that increases in terrestrial carbon uptake due to ongoing anthropogenic N loading may be greater than previously thought.Kalmia latifolia.\u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0\u00a0 \u00a0 Within each of the 18 plots, we established paired 1-m radius subplots with and without K. latifolia in the understory ( \u201c+/- ErM subplot\u201d) within 2 m of the center of the 10-m radius plot. In each 1-m radius subplot, we measured trees \u22651 cm diameter at breast height (DBH; 1.37 m). We also measured DBH of all trees \u226520 cm DBH within 10 m and trees \u22655 cm DBH within 5 m of plot center. We calculated the percentage of EcM tree basal area out of total basal area, scaled to m2 ha-1. \u00a0 In June 2021, we collected and pooled two soil samples for each of three depths within the 36 paired subplots (i.e. 18 +ErM and 18 -ErM subplots). The three depths included: (1) the Oa horizon (depth varied depending on the thickness of the horizon); (2) the top 10 cm of the A horizon, beginning at the base of the Oa horizon; and (3) a second, contiguous A horizon sample that reached a cumulative sampling depth of 30 cm, inclusive of the depth of the Oa horizon. For the organic layer, we removed the litter layer (i.e. the Oi and Oe horizons) and collected and pooled two 25 by 25-cm areas of the Oa horizon using a square template. For the mineral layers, we collected two contiguous depth increments from the A horizon within the footprint of the 25 by 25-cm areas using a 5.08-cm diameter hammer corer. In each instance, we recorded the exact sampling depth. Two subplots did not have an Oa horizon, so we collected a total of 106 samples (3 sites \u00d7 6 plots \u00d7 2 subplots \u00d7 3 depths \u2212 2 Oa samples). Soils were stored at 4\u00b0C prior to their analysis. \u00a0 To prepare the soil samples for analysis, we weighed and homogenized each sample, air dried a representative subsample of non-sieved soil, and passed the remaining field-moist sample through a 4-mm sieve. Using the non-sieved subsample, we estimated the mass and volume of roots and stones and calculated soil bulk density values. For total soil organic matter (SOM) content, we heated samples at 550\u00b0C for 12-h in a muffle furnace and calculated loss on ignition. \u00a0 We used a modified substrate-induced respiration method as an indicator of active saprotrophic microbial biomass. Using autolyzed yeast extract solution as a labile C substrate, we measured rates of CO2 efflux over a 4-h incubation period with an Infra-Red Gas Analyzer and calculated the rate of C-CO2 production per unit of equivalent soil dry mass. For microbially-available C, we estimated potential CO2 production rates over a 14-d incubation period. We measured CO2 efflux over 24-h periods at days 1, 5, 8, and 14 and integrated the four measurements to calculate cumulative C-CO2 production. We estimated water holding capacity by saturating each field-moist sample with water and allowing it to drain freely for 2 h. To calculate the equivalent dry mass of field-moist samples, we measured gravimetric water content by oven-drying the samples to constant mass at 105\u00b0C. \u00a0 We separated the >53 and <53\u2009\u00b5m particle size fractions to quantify particulate (POM) and mineral-associated soil organic matter fractions. We passed air-dried samples through a 2-mm sieve and then dispersed soil aggregates by shaking ~30 g of the sieved, air-dried sample with 30\u2009mL of sodium hexametaphosphate (NaHMP) solution for 18 h. We rinsed each sample over a 53-\u00b5m sieve with deionized water until the water passing through the sieve ran clear. We oven-dried the >53-\u00b5m fraction retained on the top of the sieve and a representative subsample of the <53-\u00b5m fraction suspended in solution at 70\u00b0C. To estimate the mass of the <53-\u00b5m fraction, we calculated the difference between the initial soil mass (105\u00b0C equivalent) and the recovered mass of the >53-\u00b5m fraction (105\u00b0C equivalent). To convert air-dried soil mass to oven-dried mass we dried a subsample of each air-dried sample at 105\u00b0C. Fractions were ground to a fine powder and analyzed for total carbon (C) and nitrogen (N) concentrations using a Costech ESC 4010 Elemental Analyzer. \u00a0 We used an equivalent soil mass approach to calculate soil C, N, SOM, microbial biomass, and microbially-available C stocks in three equivalent soil mass layers as well as the sum of the three layers to estimate cumulative stocks at the subplot level. Following this approach, we report stocks to a standard soil mass and therefore allow the depth of the equivalent soil mass layers to vary depending on soil bulk density. To calculate equivalent soil mass stocks, we added or subtracted elemental stocks of the deeper soil layer to the upper soil layer in 1-mm increments until the soil mass from the upper layer is closest to that of the target soil mass. We chose reference soil masses using the median or target field sampling depth and the mean bulk density value for each of the three depth increments to make them roughly equivalent to the sampled depths. Based on this method, the organic layer had an equivalent mass of ~2.5 kg soil m-2 (median Oa depth = 2.5 cm; mean Oa bulk density = 0.10 g cm-3), the surface mineral layer had an equivalent mass of ~37 kg soil m-2 (target sampling depth = 10 cm; mean bulk density = 0.37 g cm-3), and the subsurface mineral layer had an equivalent mass of ~126 kg soil m-2 (the target sampling depth was 17.5 cm for a sample with a 2.5 cm Oa depth; mean bulk density = 0.72 g cm-3). The cumulative equivalent soil mass for the subplot-level stocks was the sum of the three layers, or ~166 kg soil m-2.", "keywords": ["equivalent soil mass", "ericoid mycorrhizal fungi", "13.

We initiated a leaf litterfall manipulation experiment in a tropical rain forest in Costa Rica to test the sensitivity of surface soil C pools and fluxes to different litter inputs. After only 2\uffc2\uffa0years of treatment, doubling litterfall inputs increased surface soil C concentrations by 31%, removing litter from the forest floor drove a 26% reduction over the same time period, and these changes in soil C concentrations were associated with variations in dissolved organic matter fluxes, fine root biomass, microbial biomass, soil moisture, and nutrient fluxes. However, the litter manipulations had only small effects on soil organic C (SOC) chemistry, suggesting that changes in C cycling, nutrient cycling, and microbial processes in response to litter manipulation reflect shifts in the quantity rather than quality of SOC. The manipulation also affected soil CO 2 fluxes; the relative decline in CO 2 production was greater in the litter removal plots (\uffe2\uff88\uff9222%) than the increase in the litter addition plots (+15%). Our analysis showed that variations in CO 2 fluxes were strongly correlated with microbial biomass pools, soil C and nitrogen (N) pools, soil inorganic P fluxes, dissolved organic C fluxes, and fine root biomass. Together, our data suggest that shifts in leaf litter inputs in response to localized human disturbances and global environmental change could have rapid and important consequences for belowground C storage and fluxes in tropical rain forests, and highlight differences between tropical and temperate ecosystems, where belowground C cycling responses to changes in litterfall are generally slower and more subtle.

For the sites other than PFS, phosphate was the most important factor explaining the differences in bacterial communities across fields. Firmicutes were the most dominant group in almost all fields, except in PFS and deciduous forest soils (DFS). In PFS, Alphaproteobacteria was most represented, while in DFS, Firmicutes and Gammaproteobacteria were both highly represented. Interestingly, Bacillii and Clostridium OTUs correlated with pH and phosphate, which might explain their high abundance across many of the Dutch soils.

To explain the observed deterioration of plant growth, this study investigated the effects of P3HB microplastics on the soil microbiome and its activity related to content of nutrients and their transformation processes. A pot experiment was conducted using soil contaminated with five different doses of P3HB, both with and without maize. Soil mineral nitrogen forms, microbial properties as well as plant biomass were determined. Results: P3HB significantly altered soil properties by stimulating microbial respiration, enhancing carbon turnover, and shifting nitrogen forms, notably reducing NO\u2083\u207b availability. The fungal community was more sensitive to P3HB compared to the bacterial one. Fungal genera such as Tetracladium, Exophiala, and Pseudogymnoascus were stimulated; others such as Gibberella and Gibellulopsis declined. In the bacterial community, P3HB promoted the growth of copiotrophic P3HB degraders (e.g., Actinobacteria, Alphaproteobacteria); increased the abundance of anaerobes (Clostridia); decreased nitrifying groups (Nitrososphaeria, Nitrospiria); and reduced oligotrophic taxa (Vicinamibacteria, Thermoleophilia). These changes led to altered nutrient cycling, including inhibited nitrification and reduced mineral nitrogen availability, contributing to decreased maize growth.

However, in addition to altering biomass, afforestation can have substantial effects on soil organic carbon (SOC) pools, some of which have much longer turnover times than plant biomass. An increasing body of evidence suggests that the effect of afforestation on SOC may depend on mean annual precipitation (MAP). The goal of this study was to test how labile and bulk pools of SOC and total soil nitrogen (TN) change with afforestation across a rainfall gradient of 600\uffe2\uff80\uff931500 mm in the Rio de la Plata grasslands of Argentina and Uruguay. The sites were all former grasslands planted withEucalyptusspp. Overall, we found that afforestation increased (up to 1012 kg C\uffc2\uffb7ha\uffe2\uff88\uff921\uffc2\uffb7yr\uffe2\uff88\uff921) or decreased (as much as 1294 kg C\uffc2\uffb7ha\uffe2\uff88\uff921\uffc2\uffb7yr\uffe2\uff88\uff921) SOC pools in this region and that these changes were significantly related to MAP. Drier sites gained, and wetter sites lost, SOC and TN (r2= 0.59,P= 0.003; andr2= 0.57,P= 0.004, respectively). Labile C and N in microbial biomass and extractable soil pools followed similar patterns to bulk SOC and TN. Interestingly, drier sites gained more SOC and TN as plantations aged, while losses reversed as plantations aged in wet sites, suggesting that plantation age in addition to precipitation is a critical driver of changes in soil organic matter with afforestation. This new evidence implies that longer intervals between harvests for plantations could improve SOC storage, ameliorating the negative trends found in humid sites. Our results suggest that the value of afforestation as a carbon sequestration tool should be considered in the context of precipitation and age of the forest stand.

We conducted a meta\uffe2\uff80\uff90analysis of 122 studies to examine crop rotation effects on total soil C and N concentrations, and the faster cycling microbial biomass C and N pools that play key roles in soil nutrient cycling and physical processes such as aggregate formation. We specifically examined how rotation crop type and management practices influence C and N dynamics in different climates and soil types. We found that adding one or more crops in rotation to a monoculture increased total soil C by 3.6% and total N by 5.3%, but when rotations included a cover crop (i.e., crops that are not harvested but produced to enrich the soil and capture inorganic N), total C increased by 8.5% and total N 12.8%. Rotations substantially increased the soil microbial biomass C (20.7%) and N (26.1%) pools, and these overwhelming effects on microbial biomass were not moderated by crop type or management practices. Crop rotations, especially those that include cover crops, sustain soil quality and productivity by enhancing soil C, N, and microbial biomass, making them a cornerstone for sustainable agroecosystems.

They play multiple roles in the soil by fixing C and N and synthesizing exopolysaccharides, which increase soil fertility and water retention and improve soil structure and stability. Application of cyanobacteria as inoculants to promote biocrust development has been proposed as a novel biotechnological technique for restoring barren degraded areas and combating desertification processes in arid lands. However, previous to their widespread application under field conditions, research is needed to ensure the selection of the most suitable species. In this study, we inoculated two cyanobacterial species, Phormidium ambiguum (non N-fixing) and Scytonema javanicum (N-fixing), on different textured soils (from silt loam to sandy), and analyzed cyanobacteria biocrust development and evolution of physicochemical soil properties for 3 months under laboratory conditions. Cyanobacteria inoculation led to biocrust formation in all soil types. Scanning electron microscope (SEM) images showed contrasting structure of the biocrust induced by the two cyanobacteria. The one from P. ambiguum was characterized by thin filaments that enveloped soil particles and created a dense, entangled network, while the one from S. javanicum consisted of thicker filaments that grouped as bunches in between soil particles. Biocrust development, assessed by chlorophyll a content and crust spectral properties, was higher in S. javanicum-inoculated soils compared to P. ambiguum-inoculated soils. Either cyanobacteria inoculation did not increase soil hydrophobicity. S. javanicum promoted a higher increase in total organic C and total N content, while P. ambiguum was more effective in increasing total exopolysaccharide (EPS) content and soil penetration resistance. The effects of cyanobacteria inoculation also differed among soil types and the highest improvement in soil fertility compared to non-inoculated soils was found in sandy and silty soils, which originally had lowest fertility. On the whole, the improvement in soil fertility and stability supports the viability of using cyanobacteria to restore degraded arid soils.", "keywords": ["2.

Mineral soil measurements were restricted to the top 10 cm. Data were analyzed with both multivariate and univariate analyses of variance. Multivariate analyses were conducted with and without soil mesofauna or forest floor mesofauna, as data for those taxa were not collected on some sites. In multivariate analysis with soil mesofauna, the model giving the strongest separation among stand types (P = 0.019) included abundance and richness of soil mesofauna and anaerobic mineralizable nitrogen. The best model with forest floor mesofauna (P = 0.010) included anaerobic mineralizable nitrogen, soil moisture content, and richness of forest floor mesofauna. Old growth had the highest mean values for all variables, and in both models differed significantly from mature stands, while the latter did not differ. Old growth also averaged higher percent soil organic matter, and analysis including that variable was significant but not as strong as without it. Results of the multivariate analyses were mostly supported by univariate analyses, but there were some differences. In univariate analysis, the difference in percent soil organic matter between old growth and thinned mature was due to a single site in which the old growth had exceptionally high soil organic matter; without that site, percent soil organic matter did not differ between old growth and thinned mature, and a multivariate model containing soil organic matter was not statistically significant. In univariate analyses soil mesofauna had to be compared nonparametrically (because of heavy left-tails) and differed only in the Siskiyou Mountains, where they were most abundant and species rich in old growth forests. Species richness of mineral soil mesofauna correlated significantly (+) with percent soil organic matter and soil moisture, while richness of forest floor mesofauna correlated (+) with depth of the forest floor. Composition of forest floor and soil mesofauna suggest the two groups represent a single community. Soil moisture correlated highly with percent soil organic matter, with no evidence for drying in sites that were sampled relatively late in the summer drought, suggesting losses of surface soil moisture were at least partially replaced by hydraulic lift (which has been demonstrated in other forests of the region).

As grazing intensity increased, soil water content, carbon and nitrogen contents and stocks, and carbon to phosphorus and nitrogen to phosphorus ratios decreased, whereas soil bulk density increased. However, soil phosphorus and carbon to nitrogen ratio remained stable. Our findings highlight the negative impacts of heavy grazing intensity, in terms of soil carbon and nitrogen loss and phosphorus mineralization. Moreover, we emphasize that further related studies are necessary to gain a more comprehensive understanding of the effects of grazing on grassland ecosystems, and thereby provide information for sustainable management practices and eco-compensation policies.

Considering this knowledge gap, the effects of legume biomass from faba beans that are cultivated outdoors (FAB), or from feed-grade alfalfa pellets at two different doses (AAL = 330 g m\uffe2\uff88\uff922; AAH = 660 g m\uffe2\uff88\uff922) that were applied as MGM on the nutrition and yield of an organic greenhouse crop of tomatoes were evaluated. All of the MGM treatments increased the mineral N concentrations in the soil throughout the cropping period, and the total N concentration in tomato leaves when compared to the untreated control. FAB and AAH treatments had a stronger impact than AAL in all of the measured parameters. In addition, AAL, AAH, and FAB treatments increased the yield compared to the control by 19%, 33%, and 36%, respectively. The application of MGM, either as faba bean fresh biomass or as alfalfa dry pellets, in organic greenhouse tomatoes significantly increased the plant available soil N, improved N nutrition, and enhanced the fruit yield. However, the N mineralization rates after the MGM application were excessive during the initial cropping stages, followed by a marked decrease thereafter. This may impose an N deficiency during the late cropping period.

Chemical analyses in the laboratory indicate the concentrations of elements in soils, but the thickness and bulk density of the soil layers in the field must be considered to estimate the quantities of elements per unit area. Conventional methods that calculate organic matter storage as the product of concentration, bulk density and thickness do not fully account for variations in soil mass. Comparisons between the quantities of organic C, N, P and S in Gray Luvisol soils under native aspen forest and various cropping systems were hampered by differences in the mass of soil under consideration. The influence of these differences was eliminated by calculating the masses of C, N, P and S in an 'equivalent soil mass' (i.e. the mass of soil in a standard or reference surface layer). Reassessment of previously published data also indicated that estimates of organic matter storage depended on soil mass. Appraisals of organic matter depletion or accumulation usually were different for comparisons among element masses in an equivalent soil mass than for comparisons among element masses in genetic horizons or in fixed sampling depths. Unless soil erosion or deposition had altered the mass of topsoil per unit area, comparisons among unequal soil masses were unjustified and erroneous. For management-induced changes in soil organic matter and nutrient storage to be assessed reliably, the masses of soil being compared must be equivalent.

Here we used trenches lined with mesh screens of varying sizes to isolate mycorrhizal hyphal effects on soil C dynamics in subtropical successional forests. We found that the presence of mycorrhizal hyphae suppressed soil CO2 fluxes by 17% in early-successional forests, but enhanced CO2 losses by 20% and 32% in mid- and late-successional forests, respectively. The inhibitory effects of mycorrhizal fungi on soil CO2 fluxes in the young stands were associated with changes in soil nitrogen (N) mineralization and microbial activities, suggesting that competition between mycorrhizae and saprotrophs for N likely suppressed soil C decomposition. In the mid- and late-successional stands, mycorrhizal enhancement of CO2 release from soil likely resulted from both hyphal respiration and mycorrhizal-induced acceleration of organic matter decay.

Arid and semi-arid grassland ecosystems cover about 15% of the global land surface and provide vital soil carbon (C) and nitrogen (N) sequestration. Although half of the soil C and N is stored in deep soils (below 30 cm), no regional-scale study of microbial properties and their functions through the soil profile has been conducted in these drylands. 2. To explore the distribution and determinants of microbial properties and C and N mineralization rates through soil profile along aridity gradient at a regional scale, we investigated these variables for four soil layers (0-20, 20-40, 40-60, and 60-100 cm) in 132 plots on the Mongolia Plateau. 3. Soil microbial properties (biomass and bacteria:fungi ratio) and C and N mineralization rates decreased with increasing soil depth and aridity at the regional scale. Aridity-induced declines in soil microbial properties mainly resulted from the negative effects of aridity on ANPP/root biomass and soil organic C (SOC) in the surface soil layers (0-20 and 20-40 cm) but from the direct and indirect (via SOC and soil C/N) negative effects of aridity in the deep soil layers (40-60 and 60-100 cm). 4. Aridity-induced declines in soil C mineralization rates mainly resulted from the negative indirect effect of aridity on SOC and microbial properties in each soil layer, with weaker effects of SOC and stronger effects of soil microbes in the deep soil layers. Aridity-induced declines in soil N mineralization rates mainly resulted from the negative indirect effect of aridity on SOC in the three soil layers above 60 cm and mainly resulted from the negative direct effect of aridity in the 60-100 cm soil layer. 5. Aridity via direct or indirect effects strongly determined the patterns of soil microbial properties and C and N mineralization throughout soil profiles on the Mongolian Plateau. These findings suggest that the increases in aridity are likely to induce changes in soil microorganisms and their associated functions across soil depths of semi-arid grasslands, and future models should consider the dynamic interactions between substrates and microbial properties across soil depths in global drylands.", "keywords": ["2.
