The expansion of tropical forest into savanna may potentially be a large carbon sink, but little is known about the patterns of carbon sequestration during transitional forest formation. Moreover, it is unclear how nutrient limitation, due to extended exposure to fire\uffe2\uff80\uff90driven nutrient losses, may constrain carbon accumulation. Here, we sampled plots that spanned a woody biomass gradient from savanna to transitional forest in response to differential fire protection in central Brazil. These plots were used to investigate how the process of transitional forest formation affects the size and distribution of carbon (C) and nitrogen (N) pools. This was paired with a detailed analysis of the nitrogen cycle to explore possible connections between carbon accumulation and nitrogen limitation. An analysis of carbon pools in the vegetation, upper soil, and litter shows that the transition from savanna to transitional forest can result in a fourfold increase in total carbon (from 43 to 179 Mg C/ha) with a doubling of carbon stocks in the litter and soil layers. Total nitrogen in the litter and soil layers increased with forest development in both the bulk (+68%) and plant\uffe2\uff80\uff90available (+150%) pools, with the most pronounced changes occurring in the upper layers. However, the analyses of nitrate concentrations, nitrate\uffe2\uff80\uff8a:\uffe2\uff80\uff8aammonium ratios, plant stoichiometry of carbon and nitrogen, and soil and foliar nitrogen isotope ratios suggest that a conservative nitrogen cycle persists throughout forest development, indicating that nitrogen remains in low supply relative to demand. Furthermore, the lack of variation in underlying soil type (>20 cm depth) suggests that the biogeochemical trends across the gradient are driven by vegetation. Our results provide evidence for high carbon sequestration potential with forest encroachment on savanna, but nitrogen limitation may play a large and persistent role in governing carbon sequestration in savannas or other equally fire\uffe2\uff80\uff90disturbed tropical landscapes. In turn, the link between forest development and nitrogen pool recovery creates a framework for evaluating potential positive feedbacks on savanna\uffe2\uff80\uff93forest boundaries.

The fast turnover of leguminous green manure enables it to release N quickly, but limits its effectiveness in maintaining soil organic C content. Converting leguminous green manure into biochar facilitates its use as a soil amendment. In this study, we assessed how the conversion of leguminous green manure (Sesbania roxburghii) into biochar altered its chemical composition and subsequent C and N mineralization. Biomass was charred along a temperature gradient from 200 to 500\u00a0\u00b0C. Using nuclear magnetic resonance and near-edge X-ray adsorption fine structure spectroscopy, we found that both C and N became enriched in aromatic and heterocyclic aromatic structures in biochar, and this structural change led to a reduction in C and N mineralization rates. The mineralized C decreased from 32.7% of the added C of raw biomass to <\u00a00.5% of that of biochar at charring temperatures above 400\u00a0\u00b0C. N release shifted from N mineralization in raw biomass to N immobilization at charring temperatures at 500\u00a0\u00b0C. As such, soil amended with biochar produced at charring temperatures exceeding 400\u00a0\u00b0C demonstrated a 25% decrease in dry shoot biomass compared with unamended soil. The results indicated that the C stability of leguminous green manure can be achieved by converting raw material into biochar, but that the charring process may limit it to providing N.", "keywords": ["2.

We measured CH 4 and N 2 O emissions during two cropping seasons in the Philippines from field plots exposed to contrasting treatments during the fallow before land preparation for rice cultivation.

It is a non-selective herbicide with carboxyl, amino, and phosphonate functional groups, and it has a strong affinity to the soil mineral fraction. Sorption plays a major role for the fate and transport of glyphosate in the environment. The sorption coefficient (Kd) of glyphosate, and hence its mobility, varies greatly among different soil types. Determining Kd is laborious and requires the use of wet chemistry. In this study, we aimed to estimate Kd using basic soil properties, and visible near-infrared spectroscopy (vis\u2013NIRS). The latter method is fast, requires no chemicals, and several soil properties can be estimated from the same spectrum. The data set included 68 topsoil samples collected across the South Island of New Zealand, with clay and organic carbon (OC) contents ranging from 0.001 to 0.520 kg kg\u22121 and 0.021 to 0.217 kg kg\u22121, respectively. The Kd was determined with batch equilibration sorption experiments and ranged from 13 to 3810 L kg\u22121. The visible near-infrared spectra were obtained from 400 to 2500 nm. Multiple linear regression was used to correlate Kd to oxalate extractable aluminium and phosphorous and pH, which resulted in an R2 of 0.89 and an RMSE of 259.59 L kg\u22121. Further, interval partial least squares regression with ten-fold cross-validation was used to predict Kd by vis\u2013NIRS, and an R2 of 0.93 and an RMSECV of 207.58 L kg\u22121 were obtained. Thus, these results show that both basic soil properties and vis\u2013NIRS can predict the variation in Kd across these samples with high accuracy and hence, that glyphosate sorption to a soil can be determined with vis\u2013NIRS.

N addition consistently increased microbial biomass nitrogen (MBN) at both microsites, but only decreased the ratio of MBC to MBN beneath shrubs. Both water and N addition had no impacts on the ratio of fungal to bacterial PLFAs (F:B), suggesting no impacts of water or N addition on microbial community composition. Microbial biomass, respiration, bacterial and fungal PLFAs were positively related to soil water content across treatments, suggesting that the increasing MR under increasing precipitation was mainly contributed by increasing microbial biomass rather than altering microbial community composition. In addition, the interaction of precipitation and N addition on microorganisms is discrepant between interplant and beneath shrubs, with significant effects beneath shrubs and no impacts in interplant.

However, most present knowledge on the impact of agroforestry systems on soil organic carbon (SOC) storage comes from tropical systems. This study was conducted in southern France, in an 18-year-old agroforestry plot, where hybrid walnuts ( Juglans regia \u00d7 nigra L.) are intercropped with durum wheat ( Triticum turgidum L. subsp. durum ), and in an adjacent agricultural control plot, where durum wheat is the sole crop. We quantified SOC stocks to 2.0\u00a0m depth and their spatial variability in relation to the distance to the trees and to the tree rows. The distribution of additional SOC storage in different soil particle-size fractions was also characterized. SOC accumulation rates between the agroforestry and the agricultural plots were 248\u00a0\u00b1\u00a031\u00a0kg\u00a0C\u00a0ha \u2212\u00a01 \u00a0yr \u2212\u00a01 for an equivalent soil mass (ESM) of 4000\u00a0Mg\u00a0ha \u2212\u00a01 (to 26\u201329\u00a0cm depth) and 350\u00a0\u00b1\u00a041\u00a0kg\u00a0C\u00a0ha \u2212\u00a01 \u00a0yr \u2212\u00a01 for an ESM of 15,700\u00a0Mg\u00a0ha \u2212\u00a01 (to 93\u201398\u00a0cm depth). SOC stocks were higher in the tree rows where herbaceous vegetation grew and where the soil was not tilled, but no effect of the distance to the trees (0 to 10\u00a0m) on SOC stocks was observed. Most of the additional SOC storage was found in coarse organic fractions (50\u2013200 and 200\u20132000\u00a0\u03bcm), which may be rather labile fractions.

The objective of this study was to evaluate direct and indirect effects of climate on litter decomposition along an altitudinal gradient in a temperate Alpine region. Foliar litter of European beech (Fagus sylvatica) and Black pine (Pinus nigra) was incubated in litterbags during two years in the Hochschwab massif of the Northern Limestone Alps of Austria. Eight incubation sites were selected following an altitudinal/climatic transect from 1900 to 900\u00a0m\u00a0asl. The average remaining mass after two years of decomposition amounted to 54% (beech) and 50% (pine). Net release of N, P, Na, Al, Fe and Mn was higher in pine than in beech litter due to high immobilization (retention) rates of beech litter. However, pine litter retained more Ca than beech litter. Altitude retarded decay (mass loss and associated C release) in beech litter during the first year only but had a longer lasting effect on decaying pine litter. Altitude comprises a suite of highly auto-correlated characteristics (climate, vegetation, litter, soil chemistry, soil microbiology, snow cover) that influence litter decomposition. Hence, decay and nutrient release of incubated litter is difficult to predict by altitude, except during the early stage of decomposition, which seemed to be controlled by climate. Reciprocal litter transplant along the elevation gradient yielded even relatively higher decay of pine litter on beech forest sites after a two-year adaptation period of the microbial community.", "keywords": ["Pinus nigra", "0106 biological sciences", "Decomposition", "Fagus sylvatica", "Soil Science", "04 agricultural and veterinary sciences", "15.

Despite the influence of SOM chemistry\u2014here defined as soil organic C (SOC) and soil organic N (SON) functional groups and compounds\u2014on decomposition, uncertainty exists regarding the response of SOM chemistry to climate change and associated land use shifts. Here, we adopt a climosequence approach, using latitude along a uniform glacial till deposit at the grassland\u2013forest ecotone in central Canada as a surrogate for the effects of climate change on SOM chemistry. Additionally, we evaluate differences in SOM chemistry from paired native grassland, native trembling aspen ( Populus tremuloides ) forest, and arable soil profiles to investigate the effects of likely climate-induced land use alterations. The combination of C and N K -edge X-ray absorption near edge structure (XANES) with pyrolysis-field ionization mass spectrometry (Py-FIMS) techniques was used to examine SOM chemistry at atomic and molecular scales, respectively. These techniques revealed only modest differences in surface SOM chemistry related to land use and latitude. Greater variation was apparent in the vertical stratification of SOM constituents from soil depth profiles. These findings indicate that pedon-scale processes have greater control over SOM chemistry than do processes operating on landscape (e.g. land use) and regional (e.g. climate) scales. Additionally they imply that SOM chemistry is largely unresponsive to climatic change on the magnitude of the mean annual temperature (MAT) gradient under study (~\u00a00.7\u00a0\u00b0C), despite its location at the grassland\u2013forest boundary highlighting its sensitivity, and is similarly unresponsive to associated land use shifts.", "keywords": ["Vegetation", "Ecology and Evolutionary Biology", "Plant Sciences", "Agriculture", "Genetics and Genomics", "04 agricultural and veterinary sciences", "15.

Several weathering indices (Weathering Index of Parker \u2013 WIP \u2013, Chemical Index of Alteration \u2013 CIA \u2013, Chemical Index of Weathering \u2013 CIW \u2013, Plagioclase Index of Alteration \u2013 PIA \u2013 and Silica\u2013Titania Index \u2013 STI \u2013) and multivariate statistical analysis (principal components analysis), based on chemical composition, were used. With the only exception of the STI, the indices were highly correlated (r\u00a0>\u00a00.85). The highest WIP and STI values (20.9\u00a0\u00b1\u00a08.2 and 70.2\u00a0\u00b1\u00a02.2 respectively) were found for soils developed on basalt flows near the coast. Slightly lower values (WIP 16.8\u00a0+\u00a05.1 and STI 61\u00a0\u00b1\u00a03.4) were shown by brown soils developed from basaltic flows at elevations between 140 and 225\u00a0m\u00a0a.s.l. While the lowest values (WIP 9\u00a0\u00b1\u00a05 and STI 47\u00a0\u00b1\u00a06.8), representing the more weathered materials, were found for soils located at the highest elevations (>\u00a0400\u00a0m\u00a0a.s.l.) and mostly developed on pyroclastic materials (tuff and tephra). As the chemical composition of the geological material (basalt and tephra) is highly homogeneous, the degree of weathering is likely to depend on climatic conditions controlled by altitude and orientation. On the windward slopes of the island a gradient of increasing weathering is observed from the arid conditions predominant at the coast to elevations of 400\u2013500\u00a0m\u00a0a.s.l., where much more humid conditions prevail. Principal component analysis on elemental composition also supported the interpretation that the degree of weathering (first component) and soil horizonation (second component) are both related to climatic conditions. Both, the variation of the chemical indices and the principal components of the geochemical composition are related to the bioclimatic zones: soils with the lowest degree of weathering are located in the arid coastal zone; slightly higher intensity was found for soils located in the transition and Scalesia zones; while the most weathered soils appear in the brown zone. Compared to other volcanic soils studied in the literature, soils from Isla Santa Cruz are in the upper range of chemical weathering intensity, only comparable to soils from Azores Islands and Canary Islands (Tenerife and La Gomera) developed on basalts, under oceanic conditions.", "keywords": ["13.

Moreover, it is uncertain whether N2O emission reductions would persist after prolonged biochar incorporation in the field. In this study, we incorporated four biochar types in a loam textured cropland field and intact soil cores were sampled to investigate the physical control of biochar on denitrification after 7\u00a0months. During a first incubation experiment, we measured N2O emissions from undisturbed and disturbed (i.e. sieved (2\u00a0mm) and grounded) soil cores. Both in the disturbed and undisturbed soil cores biochar at water filled pore space (WFPS) of 80% reduced the N2O emissions by 50\u201390%, refuting the hypothesis that biochar exerts an indirect physical control over soil denitrification several months after incorporation. Secondly, we hypothesized that biochar creates denitrification \u2018hotspots\u2019 in soil, where complete reduction of N2O to N2 is promoted compared to non-amended soil. In these hotspots biochar particles could act as microlocations with local anaerobic conditions and local higher pH, stimulating in this way complete denitrification. Via the acetylene inhibition method we did not observe a reduction in the N2O/(N2O\u00a0+\u00a0N2) ratio, which could suggest that biochar did not promote the reduction of N2O to N2.

The effectiveness of grazing exclusion on sequestering soil organic carbon, increasing total nitrogen and improving soil biological activity has been documented in literature. Few studies, however, have examined the responses of phosphorus (P) fractions and arbuscular mycorrhizal fungi (AMF) diversity to long-term grazing exclusion. In this study, the variations of soil chemical properties, the status of inorganic and organic P fractions in the rhizosphere soil, and the AMF diversity in roots of Leymus chinensis , Stipa krylovii and Cleistogenes squarrosa and in bulk soils were investigated in continuously grazed and ungrazed paddocks (exclusion from grazing for 10\u201312\u00a0years) on typical and meadow steppes in Inner Mongolia, aiming to evaluate the effectiveness of grazing exclusion in improving AMF diversity and soil P status. Grazing exclusion altered plant species compositions and increased aboveground biomass and ground cover, resulting in increased concentrations of soil organic carbon and total nitrogen. The concentration of total phosphorus increased in typical steppes but reduced in meadow steppes, while the concentrations of available P and most P fractions remained unchanged or reduced following 10\u201312\u00a0years of grazing exclusion. Grazing exclusion improved AMF colonization in meadow steppes, but not in typical steppes, attributing to the differences in soil quality, plant species, and AMF phylotypes between two types of steppes. AMF diversity was positively correlated with soil pH, concentrations of soil total nitrogen, total organic carbon, total P, Ca 10 \u2013P, medium labile organic P, and the activity of alkaline phosphatase, indicating that, on semi-arid steppes in northern China, improved soil conditions would increase the AMF diversity, thus enhancing the productivity of the steppe ecosystem.

Several land management practices such as the suppression of tillage in agroecosystems and livestock exclusion in grasslands had initially been thought to store more carbon into the soil, but recent research puts this into question. In a context where finding effective C sequestration methods is urgent, the main objective of this study was to assess the ability of an innovative grassland management practice based on high density and short duration (HDSD) grazing to sequester atmospheric C into soils. The study was performed in a degraded communal rangeland in South Africa where soil organic C (SOC) depletion ranged from 5 to 95% depending on the degradation level, which varied from non-degraded (ND; with grass above ground coverage, Cov of 100%), degraded (D1; 50 < Cov < 75%), D2 (25 < Cov < 50%) and HD (highly degraded: Cov < 5%). The ability of HDSD (1200 cows ha\u2212 1 for 3 days a year) to replenish SOC stocks was compared to four commonly used strategies: (1) livestock exclosure (E); (2) livestock exclosure with topsoil tillage (ET); (3) livestock exclosure with NPK fertilization (2:3:3, 22 at 0.2 t ha\u2212 1) (EF); (4) annual burning (AB); all treatments being compared to traditional free grazing control. A total of 540 soil samples were collected in the 0\u20130.05 m soil layer for all treatments and degradation intensities. After two years, topsoil SOC stocks were significantly increased under EF and HDSD, by an average of 33.4 \u00b1 0.5 and 12.4 \u00b1 2.1 g C m2 y\u2212 1, respectively. In contrast, AB reduced SOC stocks by 3.6 \u00b1 3.0 g C m2 y\u2212 1, while the impact of E and ET was not significant at P < 0.05. HDSD replenished SOC stocks the most at D1 and D2 (6.7 and 7.4% y\u2212 1) and this was explained by grass recovery, i.e. a significant increase in soil surface coverage by grass and grass production. HDSD is cost-effective, and thus has great potential to be widely adopted by smallholder farmers.", "keywords": ["2.

However, many crop rotations have a low amount of organic residue returned to the soil since the whole aboveground crop biomass is harvested and exported. To compensate for such organic outputs and to improve soil quality, the introduction of winter cover crops in rotations has been suggested. A 4-year controlled field experiment was conducted to quantify the respective and combined effects of chemical N fertilisation and winter cover crops on plant productivity, organic carbon (C) and N inputs from crop residues and cover crops, changes in soil C and N concentrations, C:N ratio, soil mineral N, pH, soil moisture and soil bacterial biodiversity. A ploughing tillage system with low organic input was assessed, for which the main crops were spring wheat, green pea, forage maize, along with cover crops of different legume and non-legume species. N fertilisation did not have an impact on the aboveground biomass except following forage maize. Cover crops increased the total amount of C and N inputs, irrespective of N fertilisation which had no significant effect. The soil N concentration decreased in all treatments, particularly when N fertilisers were applied under bare fallow conditions. The latter treatment also caused decreased soil C concentrations (slightly increased in the other treatments) and decreased bacterial biodiversity (no change in the other treatments). Bacteria from the Proteobacteria and Bacterioidetes phyla were highly correlated with soil from fertilised bare fallow conditions. While Verrucomicrobia was characteristic of non-fertilised bare fallow soils, Acidobacteria and Cyanobacteria were associated with the high C and N concentrations present in soils following cover crop treatments. Taken together, these results demonstrate that in ploughing systems, under low organic restitution regimes, intensive N fertilisation decreases the diversity of the bacterial soil community and reduces soil C and N concentrations, but only in bare fallow conditions. There is a protective effect of winter cover crops against the deleterious effect of chemical N fertilisation on soil biodiversity and nutrient cycling, since they can maintain soil C and N concentrations. The use of winter cover crops containing legumes is thus a practice that is able to meet the criteria of a sustainable agriculture.", "keywords": ["2.

There is evidence that the turnover of BC in soils also depends on the soil mineral assembly. We studied the effects of paddy and non-paddy soil management and different major reference soil groups on BC storage. We hypothesized that overall BC storage in soil relates to paddy management and the abundance of reactive mineral phases such as Fe and Al oxides, and clay-sized minerals. Parallel to BC, black nitrogen (BN) should accumulate in soil. Paddy and non-paddy soils were sampled in three different climate zones (tropical, subtropical, and temperate). The soil profiles comprised six replicates of Andosols, Alisols and Vertisols from Java (Indonesia), and Alisols and Cambisols from China, as well as one Fluvisol and Gleysol from Northern Italy. Samples were taken by horizon down to >\u00a01\u00a0m depth and analyzed for soil organic carbon (SOC) and BC. The latter was analyzed by oxidation to benzene polycarboxylic acids. Abundance of BN (as aromatic N) was estimated by X-ray photoelectron spectroscopic analyses of selected topsoil horizons. In topsoils BC vs. SOC accumulation was affected by management for Andosol, Alisols in China, and Vertisols. However, both flooding and crop-residue management seemed to control this. BC contents relative to SOC also differed between the reference soil groups, independent of management (p\u00a0<\u00a00.0001), yet were surprisingly constant within replicates. We conclude that BC co-accumulated with SOC in all soils. However, the overall storage of BC (1\u00a0m depth) was affected by a combination of soil group and management. Vertisols contained the largest BC stocks (17\u201319\u00a0t\u00a0ha\u2212\u00a01 in non-paddy and paddy fields), followed by Andosols and Alisols (6\u201310\u00a0t\u00a0BC\u00a0ha\u2212\u00a01 under paddy management; 3\u20138\u00a0t\u00a0ha\u2212\u00a01 under non-paddy management). The Gleysol and Fluvisol had the smallest BC stocks, independent of soil use (3\u20134\u00a0t\u00a0ha\u2212\u00a01). Aromatic N proportions increased to >\u00a050% of total N after combustion of rice straw. However, aromatic N was barely, or not detectable in soil, and there was no correlation to BC. We conclude that burned crop residues were not a major source for aromatic N in soil. BC and aromatic N showed no distinct relations to soil properties, such as the abundance of clay-sized minerals, and Al and Fe oxides. Differences in BC stocks between the soils were most pronounced in the subsoils, likely caused by physical processes, such as swelling and shrinking of clays and/or translocation by leaching. Climate and regional soil-adjusted management also affected BC accumulation, but this first snapshot indicates that global BC maps may be linked to global soil maps.", "keywords": ["2.

Soil organic carbon was measured in pasture, silvopastoral tree, and woodland treatments at six depths representative of 0\u2013150\u00a0cm. Fourteen years after tree planting, the organic carbon content in the surface soil layer (0\u201310\u00a0cm) was greatest in the pasture (6.0\u00a0g 100\u00a0g\u2212\u00a01) and least in the woodland (4.6\u00a0g 100\u00a0g\u2212\u00a01); the value (5.3\u00a0g 100\u00a0g\u2212\u00a01) below the silvopastoral trees was intermediate.

Different crop management strategies, such as drainage of paddy soils and climate-smart residue management, are essential in order to mitigate GHG emissions from flooded rice systems, but they often conflict with practical management preferences. The aim of this study was to assess the potential of early-season drainage for mitigating CH4 and N2O emissions from soils with and without added organic amendments in relation to native soil organic carbon (SOC). Rice plants were grown in pots under controlled conditions in a growth chamber with different treatments in a 2\u00a0\u00d7\u00a02\u00a0\u00d7\u00a03 factorial design. The treatments included an arable soil with two different carbon levels: 1.4% (low carbon, [L]) and 2.2% (high carbon [H]); two water regimes: midseason drainage (M) and early plus midseason drainage (EM); and three nutrient treatments: one inorganic control (nitrogen fertiliser only [N]), and two organic: maize straw\u00a0+\u00a0N fertiliser (S) and maize compost\u00a0+\u00a0N fertiliser (C). An equal amount of mineral N fertiliser was applied in all treatments. Straw and compost were applied to the soils on the basis of an equivalent amount of C added in each organic treatment. The results revealed rapid mineralization of organic C in the double-drained system, resulting in lower total CH4 emissions in treatments under early plus midseason drainage compared to those under midseason drainage only. Total CH4 emissions were reduced by 89% and 92% in the S\u00a0+\u00a0EM treatments in low C soils and high C soils respectively, as compared to S\u00a0+\u00a0M. The drainage effects on CH4 emissions from compost amendments were only significant in the low C soil, with a 61% reduction in EM compared to M drainage. N2O emissions from non-organic treatments in EM were 87% higher than in M under low C soils. The concentrations of dissolved organic carbon (DOC) were higher in organic treatments and decreased by the end of growth period.

This study aims to quantify how the chemical and physical properties of peat change during land conversion to oil palm. This will be addressed by comparing four separate stages of conversion; namely, secondary peat swamp forests, recently deeply drained secondary forests, cleared and recently planted oil palm, and mature oil palm plantation in North Selangor, Malaysia. Results indicate accelerated peat decomposition in surface peats of mature oil palm plantations due to the lowered water table and altered litter inputs associated with this land-use change. Surface organic matter content and peat C stocks at secondary forest sites were higher than at mature oil palm sites (e.g. C stocks were 975 \u00b1 151 and 497 \u00b1 157 Mg ha\u2212 1 at secondary forest and mature oil palm sites, respectively). Land conversion altered peat physical properties such as shear strength, bulk density and porosity, with mirrored changes above and below the water table. Our findings suggest close links between the organic matter and C content and peat physical properties through the entire depth of the peat profile. We have demonstrated that conversion from secondary peat swamp forest to mature oil palm plantation may seriously compromise C storage and, through its impact on peat physical properties, the water holding capacity in these peatlands.", "keywords": ["GE", "QH301 Biology", "G Geography (General)", "Q Science (General)", "04 agricultural and veterinary sciences", "15.

However, its biomass application may increase greenhouse gas (GHG) emissions, particularly methane (CH4), during flooded rice cultivation. To evaluate the effect of cover cropping and its biomass application on the annual net GWP in a mono-rice cultivation system, we evaluated the emission rates of CH4, nitrous oxide (N2O), and carbon dioxide (CO2) under different cover cropping during the fallow and rice-growing seasons. In cover cropping treatments, barley, hairy vetch, and a barley and hairy vetch mixture were cultivated as winter cover crops without fertilization during the fallow season. Moreover, the total aboveground biomass was incorporated as a green manure one week before rice transplanting. The recommended levels of chemical fertilizers were applied for rice cultivation in the control treatment (NPK) for comparison. The emission rates of CH4, soil respiration, and N2O gases were simultaneously monitored once a week using the closed-chamber method. However, the soil respiration fluxes included only soil respiration and excluded soil C sequestration through cover cropping and its biomass recycling. The net ecosystem C budget (NECB), which is defined as the difference between the total organic C input and output, was estimated to ascertain the pure soil respiration emission fluxes by mass balance approach. Finally, the net GWP was compared among treatments for the two cultivation seasons. During the dry fallow season, cover cropping significantly increased the soil respiration, and this treatment mineralized C loss significantly increased the seasonal net GWP. In comparison, the cover crop biomass application as green manure increased the soil C balance (NECB) during the rice growing season but more significantly increased the CH4 emission. As a result, the cover cultivation and its biomass application greatly increased the annual net GWP scale upon cover cropping rice paddy soil. Therefore, soil management practices that can decrease CH4 emission during rice cultivation should be adopted in cover cropping of the rice paddy soil.", "keywords": ["2. Zero hunger", "13.

Yet, their global area is still declining owing to conversion to non-forest land uses. While studies have been conducted on mangrove soil C stocks, our knowledge on how C stocks of mangrove forests compare with those of non-forest land uses that replaced them is still limited. This knowledge is crucial in land use planning and decision-making in the coastal zone. Site-scale mapping and assessments of mangrove soil C stocks and the land uses that replaced them are also limited. The aim of this study was to quantify and compare the soil C stocks in mangrove forests and their competing non-forest land uses (represented by aquaculture pond, coconut plantation, salt pond and cleared mangrove), estimate soil C loss arising from conversion, and model the soil C stock distribution in the entire study site. On the average, the soil C stock of mangrove forests was 851.9 \u00b1 87 MgC ha\u2212 1 while that of their non-forest competing land uses was less than half at 365.1 \u00b1 31 MgC ha\u2212 1. Closed canopy mangrove was highest at 1040 \u00b1 104 MgC ha\u2212 1, followed by open canopy mangrove (640 \u00b1 131 MgC ha\u2212 1) while aquaculture, salt pond and cleared mangrove had comparable C stocks (454 \u00b1 32, 401 \u00b1 9, 413 \u00b1 25 MgC ha\u2212 1, respectively) and coconut plantation had the least (42 \u00b1 0.7 MgC ha\u2212 1). Overall, the reduction in soil C stock (soil C loss) due to land use conversion in mangrove ranged from 398 to 809 MgC ha\u2212 1 (mean: 486.8 MgC ha\u2212 1) or a decline of 57% in soil C stock, on the average. It was possible to model the site-scale spatial distribution of soil C stocks and predict their values with 85% overall certainty using the Ordinary Kriging approach.

Studies have shown that soil fauna can significantly affect greenhouse gas emissions. To date, although there were some studies on the effect of interactions of soil fauna on soil CO 2 and N 2 O emissions, the role of soil fauna on CO 2 and N 2 O emissions is far from settled, especially for a wide variety of soil and human practices. Therefore, we studied how the interactions between different groups of soil fauna affect soil CO 2 and N 2 O emissions from an arable black soil (Typic Hapludoll, USDA Soil Taxonomy) subjected to conservation tillage for 13\u00a0years. We conducted a 35-day microcosm experiments with black arable soil and hay residues. The following soil fauna groups were included in our experiments: earthworms ( Eisenia fetida (Savigny 1826)), Collembola ( Thalassaphorura encarpata (Denis 1931) and Allonychiurus songi (Sun and Wu 2012)) and predatory mites ( Hypoaspis kirinensis (Chang et al., 1963)). The presence of earthworm and Collembola significantly enhanced soil N 2 O emissions ( P 2 emissions (16\u00a0days later) ( P \u00a0>\u00a00.05). The addition of micro-size predator mites to microcosms did not enhance soil CO 2 or N 2 O emissions. This suggests the presence of earthworms in microcosms can increase soil CO 2 and N 2 O emissions. In addition, the effects of predators with different species and their interactions with other groups on soil properties should be considered. This study indicates that earthworm plays the dominant roles in soil CO 2 and N 2 O emissions, especially with other soil mesofauna, such as Collembola. Also, our data analyses demonstrate that higher contents of available soil C and N can result in higher CO 2 and N 2 O emissions.", "keywords": ["2. Zero hunger", "13.

However, few studies have explored in detail the differences and similarities in the responses of belowground microbial communities to long-term N and P inputs. Using a high-throughput Illumina Miseq sequencing platform, we characterized the bacterial communities in a semi-arid steppe subjected to long-term N or P additions. Our results showed that both the Chao richness and Shannon's diversity were negatively correlated to N input rate, while only Chao richness was significantly and negatively correlated to P input rate. Also, both N and P additions altered the bacterial community structure. The bacterial community between plots of the same N or P input rate was much more dissimilar with the higher input level, indicating more severe niche differentiation in pots with higher N or P input. N Inputs significantly increased the relative abundance of the predicted copiotrophic groups (Proteobacteria and Firmicutes) but reduced the predicted oligotrophic groups (Acidobacteria, Nitrospirae, Chloroflexi), with the order Rhizobiales being most affected. P additions significantly affected only two phyla (Armatimonadetes and Chlorobi), which were positively correlated with P source. Results from the structural equation modelling (SEM) showed that N additions affected the bacterial community primarily by changing the pH, while P additions did so mainly by improving P availability. Our results suggest that the below-ground bacterial communities are more sensitive to N inputs, but P inputs can also play an important role in bacterial niche differentiation. These findings improve our understanding of bacterial responses to N and P inputs, and their impacts on bacterial-mediated processes, especially in the context of increasing anthropogenic nutrient inputs.", "keywords": ["2.
