In contrast to the extreme enrichment of the light isotopes of Zn and heavy isotopes of Cl in 66095, \u03b465Cu and \u03b456Fe in the sample lie within the previously reported range for lunar mare basalts (0.92\u202f\u00b1\u202f0.16\u2030 and 0.12\u202f\u00b1\u202f0.02\u2030, respectively). The lack of extreme isotopic fractionation for Cu and Fe isotopes reflects compositions inherent to 66095, with condensation of a cooling gas from impact-generated fumarolic activity at temperatures too low to lead to the condensation of Cu and Fe in the sample, but higher than required to condense Zn. Together with thermodynamic models, these constraints suggest that the gas condensed within 66095 between 700 and 900\u202f\u00b0C (assuming a pressure of 10\u22126 and an fO2 of IW-2). That the Cu and Fe isotopic compositions of sample 66095 are within the range of mare basalts removes the need for an exotic, volatile-enriched source. The enrichment in Tl, Br, Cd, Sn, Zn, Pb, Rb, Cs, Ga, B, Cl, Li relative to Bi, Se, Te, Ge, Cu, Ag, Sb, Mn, P, Cr and Fe in the \u2018Rusty Rock\u2019 is consistent with volcanic outgassing models and indicates that 66095 likely formed distal from the original source of the gas. The volatile-rich character of 66095 is consistent with impact-generated fumarolic activity in the region of the Cayley Plains, demonstrating that volatile-rich rocks can occur on the lunar surface from outgassing of a volatile-poor lunar interior. The \u2018Rusty Rock\u2019 indicates that the lunar interior is significantly depleted in volatile elements and compounds and that volatile-rich surface rocks likely formed through vapor condensation.

The results show that as an overall average across all land use change examined, land use conversions have significantly reduced soil C stocks (0.39 Mg ha\u22121 yr\u22121). Soil C stocks significantly increased after conversions from farmland to grassland (0.30 Mg ha\u22121 yr\u22121) and forest to grassland (0.68 Mg ha\u22121 yr\u22121), but significantly declined after conversion from grassland to farmland (0.89 Mg ha\u22121 yr\u22121), forest to farmland (1.74 Mg ha\u22121 yr\u22121), and forest to forest (0.63 Mg ha\u22121 yr\u22121).

There have been numerous studies on the responses of plants and soils to alpine meadow degradation across the region, but they are mostly focused on single sites and are incapable of determining a general response pattern of plants and soils to degradation on the QTP. A meta-analysis including 61 individual published studies was conducted to examine the biotic and abiotic characteristics in slightly (LDAM), moderately (MDAM), severely (SDAM), and very severely degraded alpine meadows (VDAM). The results showed that the aboveground biomass (AGB) significantly decreased (P\u202f<\u202f0.01) by 23.17%, 31.85%, 47.24%, and 66.66% in the LDAM, MDAM, SDAM, and VDAM compared with that in nondegraded alpine meadows (NDAM), respectively. The belowground biomass (BGB) did not change in the LDAM but began to decrease with the MDAM. The AGBs of graminoids significantly decreased in all degraded-level meadows, and sedges significantly decreased from MDAM to VDAM, whereas the AGBs of forbs significantly increased except in the VDAM. The Shannon-wiener index did not change until the VDAM. Soil organic matter (SOM) declined starting with the LDAM, and the magnitude of the decrease increased with degradation severity. The change in total nitrogen (TN) was similar to the change in the SOM. Significant available nitrogen (AN) decrease began with the MDAM and significant (P\u202f<\u202f0.05) available potassium (AK) decrease only occurred at depth of 0.0\u20130.1\u202fm in the SDAM and the VDAM. Soil moisture (SM) showed a significant decrease, whereas soil bulk density (BD) increased in the degraded alpine meadow. The response of AGB was significantly correlated with the changes in SOM and TN only in the SDAM and VDAM, whereas the response of BGB was significantly correlated with the changes in SOM and TN for all degraded stages. In the LDAM and MDAM, SOM and TN mainly came from the dense rooting of the turf layer, and the changes of SOM and TN thus had no correlation with AGB. However, in the SDAM and VDAM, SOM and TN mainly came from AGB and BGB, and the changes of SOM and TN were thus significantly correlated with AGB and BGB. Our results indicate that biological and biochemical processes regulate the plant and soil changes in LDAM and MDAM and that physical processes such as water and wind erosion might be responsible for the changes in plants and soils in SDAM and VDAM. Therefore, restoration strategies should be based on the processes and stages of alpine meadow degradation.

Since the industrial revolution, global emissions of carbon (C) are estimated at 270F30 Pg (Pg=petagram=10 15 g=1 billion ton) due to fossil fuel combustion and 136F55 Pg due to land use change and soil cultivation. Emissions due to land use change include those by deforestation, biomass burning, conversion of natural to agricultural ecosystems, drainage of wetlands and soil cultivation. Depletion of soil organic C (SOC) pool have contributed 78F12 Pg of C to the atmosphere. Some cultivated soils have lost one-half to two-thirds of the original SOC pool with a cumulative loss of 30\u201340 Mg C/ha (Mg=megagram=10 6 g=1 ton). The depletion of soil C is accentuated by soil degradation and exacerbated by land misuse and soil mismanagement. Thus, adoption of a restorative land use and recommended management practices (RMPs) on agricultural soils can reduce the rate of enrichment of atmospheric CO2 while having positive impacts on food security, agro-industries, water quality and the environment. A considerable part of the depleted SOC pool can be restored through conversion of marginal lands into restorative land uses, adoption of conservation tillage with cover crops and crop residue mulch, nutrient cycling including the use of compost and manure, and other systems of sustainable management of soil and water resources. Measured rates of soil C sequestration through adoption of RMPs range from 50 to 1000 kg/ha/year. The global potential of SOC sequestration through these practices is 0.9F0.3 Pg C/year, which may offset one-fourth to one-third of the annual increase in atmospheric CO2 estimated at 3.3 Pg C/year. The cumulative potential of soil C sequestration over 25\u201350 years is 30\u201360 Pg. The soil C sequestration is a truly win\u2013win strategy. It restores degraded soils, enhances biomass production, purifies surface and ground waters, and reduces the rate of enrichment of atmospheric CO2 by offsetting emissions due to fossil fuel.

We selected a site with a homogeneous Typic Acric Red\u2013Yellow Latosol (Anionic Acrustox). Part of this site was maintained under native vegetation (grassy cerrado C 4 -dominated), and part was planted with riparian species (C 3 ) in 1992. Litter and soil samples were collected and analysed (total organic carbon, total nitrogen, \u03b4 13 C isotopic analysis, and SOM density fractionation). Due to the predominance of grasses, carbon input was mainly below ground in cerrado. In such a soil, the decomposition process was more efficient, and much C and N were transferred to the heavy fraction. When forest was planted, there was a change from belowground to aboveground litter input (largely superficial), leading to higher C and N stocks in the light and lower stocks in the heavy fraction (resulting in lower stocks for bulk soil). The introduction of the C 3 vegetation decreased the soil \u03b4 13 C signature. It has occurred particularly in the topsoil (0\u20135 cm) due to the deposition of C 3 litter on the soil surface. At the same time, the presence of cerrado-remaining C below 5 cm maintained higher \u03b4 13 C values in this layer. During the 8 years after forest plantation, the input mode influenced both the \u03b4 13 C distribution with depth, and the C replacement: between 0 and 2.5 cm, nearly 50% of cerrado-derived C was replaced by forest-derived C, while below 5 cm, replacement was around 20%. The relatively rapid C dynamics in this Oxisol (27% replacement in the top 20 cm after 8 years of forest plantation) shows that, under tropical conditions, significant changes may occur in a short period of time.", "keywords": ["delta-c-13", "decomposition", "c-13 natural-abundance", "particle-size fractions", "turnover", "0401 agriculture", " forestry", " and fisheries", "vegetation changes", "04 agricultural and veterinary sciences", "15.

A 4-year field experiment was conducted to determine the effects of different nutrient and water regimes on paddy soil organic carbon quality by measuring the major SOC fractions. Four nutrient regimes were compared: (i) control; (ii) chemical fertilizers only (CF), (iii) combined application of chemical fertilizers with farmyard manure (FYM) (CM), and (iv) combined application of chemical fertilizers and wheat straw (CS). Two soil water regimes included continuous waterlogging (CWL) and alternate wetting and drying (AWD). The total organic carbon (TOC) and total nitrogen (TN) in paddy soil were 40-60% and 37-67% higher in the combined organic sources and chemical fertilizers treatment against the sole chemical fertilizers treatment (CF), especially under continuous waterlogging (CWL). By fractionalizing SOC, it was observed that, under the water regimes of CWL, easily oxidizable carbon (EOC), particulate organic carbon (POC), light fraction organic carbon (LFOC), microbial biomass carbon (MBC), and mineralizable organic carbon (MNC) in the organically treated paddy soil were significantly (P 250 mum (WSA) decreased by 42-45% and clay dispersion ratio (R(CD)) increased by 12-38%, as compared to the water regimes of AWD, when FYM or wheat straw was incorporated into paddy soil. Correlation analysis showed that, under the water regimes of AWD, WSA was significantly and positively related to EOC, LFOC and POC with the coefficients (r) of 0.822, 0.889, 0.912 (P<0.01), respectively. R(CD) was negatively correlated to EOC, LFOC and POC with the r=-0.796, -0.854, and -0.897 (P<0.01), respectively, under AWD. Under the water regimes of CWL, there were no significant (P<0.05) correlations between WSA as well as R(CD) and any organic carbon fraction except POC. (C) 2004 Elsevier B.V.

In both experiments with lower (Experiment 1) and higher (Experiment 2) application rates of mineral fertilizer, in the whole 0\u201330 cm layer in the minimum soil tillage systems (MT1 and MT2), the content of humus significantly increased, and in the shallow tillage system (ShT), it did not differ significantly, compared with conventional tillage (CT).

The SOC concentration and the C/N ratio were greater for macroaggregates (>250 \u03bcm) than microaggregates ( 1000 \u03bcm. The major part (86-91%) of the SOC was associated with the heavy mineral fraction at the grassland, maize and wheat site. In the A horizon of the spruce stand, the particulate organic matter accounted for 52% of the total SOC content. The C/N ratios of density fractions decreased in the order free POM occluded POM>Mineral-SOM for all soils and depths. The mean age of organic carbon in the water-stable aggregates in the Ap horizon of the maize site increased with decreasing aggregate size from 35 yr (>1000 \u03bcm) to 86 yr (<53 \u03bcm). For the density fractions the order was free POM (22 yr) 75% grass), a bare land without any vegetation (BL), and a cropland used for growing wheat (CL). Analysis of the soils revealed that (1) the sand content of the top 15 cm of soil increased from 50.14 to 85.61 g/kg, (2) the soil carbon decreased from 9.94 to 3.11 g organic carbon per kg soil, (3) the soil nitrogen content decreased from 0.223 to 0.844 g nitrogen per kg soil, and (4) the fractal dimension of PSD decreased from 2.92 to 2.45, following the order IGB > WCG > BL > CL. Thus, land use had considerable influences on the fractal dimension of PSD and various other soil properties. Further, this study shows that the fractal dimensions of PSD can be a useful parameter to monitor soil degradation induced by land use patterns and changes. (c) 2005 Elsevier B.V.

In many regions agricultural fields are just one component of a complex landscape matrix and understanding the interactions between agricultural fields and other landscape components such as wetlands is crucial for comprehensive, whole-landscape accounting of soil organic carbon (SOC) change. Our objective was to assess the effects of management and erosional history on SOC storage in wetlands of a typical hummocky agricultural landscape in southern Saskatchewan. Wetlands were classed into three land management groups: native wetlands (i.e., within a native landscape), and uncultivated and cultivated wetlands within an agricultural landscape. Detailed topographic surveys were used to develop a digital elevation model of the sites and landform segmentation algorithms were used to delineate the topographic data into landform elements. SOC density to 45 cm was assessed at seven uncultivated wetlands, seven cultivated wetlands, and twelve native wetlands. Mean SOC density decreased from 175.1 mg ha? 1 to 30 cm (equivalent mass depth) for the native wetlands to 168.6 mg ha? 1 for the uncultivated wetlands and 87.2 mg ha? 1 for the cultivated wetlands in the agricultural field. The SOC density of sediment depositional fans in the uncultivated wetlands is high but the total SOC stored in the fans is low due to their small area. The uncultivated wetlands occupy only 11% of the site but account for approximately 23% of SOC stores. Re-establishing permanent vegetation in the cultivated wetlands could provide maximum C sequestration with minimum energy inputs and a minimum loss of productive acreage but the overall consequences for the gas emissions would have to be carefully assessed.", "keywords": ["2.

The practice most often focused on is deforestation through slash-and-burn cultivation (tavy), and shifting cultivators are often portrayed as being ignorant, poverty-stricken peasants felling trees for fields and food. However, there is uncertainty whether soil degradation is related to recent tavy or earlier forest clearance, and whether some highland areas were ever forested. In this paper we use stable isotopes (\u03b413C) and diffuse reflectance spectroscopy (DRS) to study the impacts of deforestation and various other land use changes on ecosystem properties, soil organic carbon (SOC) dynamics and soil quality (fertility) in the highlands of Madagascar. Land cover transitions (between C3 and C4 systems) are defined and quantified in the study area. Historical land use had greater effect on soil organic carbon concentrations than current land use, with cultivated areas previously under C3 and C4 systems having 37.3 and 14.8 g SOC kg\u2212\u00a01, respectively. Grasslands previously under C3 had approximately 124% more SOC than grasslands previously under C4, while SOC concentrations were 65.3 and 54.9 g C kg\u2212\u00a01 under natural forest and in mixed fallow systems, respectively.

Therefore, the aim of this study is to determine the impact of a conversion from cropland to grassland on soil properties in two districts of the Lahn-Dill Highlands, Germany. We determined a land use history for the period 1945\u20132004 from aerial photographs and field surveys. This land use history was used to build a chronosequence of grassland sites with a different age since the conversion from cropland for both districts. Each chronosequence was sampled to determine bulk density, pH, coarse material fraction, C/N ratio and soil C and N content as a function of grassland age. Results showed that there was no clear dependency of soil properties on grassland age for both districts. It was concluded that observed differences within each district are much more related to differences in soil parent material or slope position, instead of land use. Interestingly, the reduction of the chronosequence analysis to a paired site survey led to an opposite conclusion for the Erda district because all investigated soil properties were significantly different for continuous grassland and cropland. This indicates that care is required when interpreting results from paired site surveys, especially when the equality of initial soil conditions is not (or cannot be) tested.", "keywords": ["2.

Total carbon and 13 C analyses were used to evaluate the changes in soil organic carbon (SOC) pools associated with land use changes using a comparative approach. Forest clearing followed by continuous cultivation of crops caused a loss of 43% (75.4\u00a0Mg ha \u2212\u00a01 ) total SOC and 73% (128.4\u00a0Mg ha \u2212\u00a01 ) forest derived SOC after nearly 75\u00a0years. The net loss of SOC was lower because of addition of 53.0\u00a0Mg ha \u2212\u00a01 of SOC of C 4 crop origin (mainly maize) to the farmland. On the other hand, afforestation of farmland led to a net accretion of SOC of 69.6 and 29.3\u00a0Mg ha \u2212\u00a01 after 20\u00a0years under Cupressus lusitanica and Pinus patula stands, respectively . The SOC accretion of plantation origin amounted to 63.3\u00a0Mg ha \u2212\u00a01 under C. lusitanica and 24.2\u00a0Mg ha \u2212\u00a01 under P. patula. Contrary to the results obtained in some other studies, the SOC of C 4 origin did not decline in these stands. This could be attributed to pasture grasses of C 4 origin that took over after land abandonment and continued to grow under the tree canopies. The grasses could thus have compensated for the SOC loss. SOC might also have been close to a steady state under the pre-plantation period. Based on the SOC amount found in a reference stand of native forest, afforestation with Eucalyptus grandis during 20\u00a0years, preceded by 20\u00a0years of cultivation and 35\u00a0years of pasture, returned the total SOC to nearly pre-deforestation levels.

The experiment with crop rotation of winter wheat and summer maize started in 1990 and had seven treatments receiving N, P, and K at the same rates if it was applied. The treatments were inorganic fertilization (NPK, NP, PK, NK), organic fertilization (ON), half amount of N from inorganic fertilizer and another half from compost (1/2ON), and no fertilization as control (CK). On average, over 14\u00a0years (1990\u20132003), both wheat and maize yields were the highest and most stable in the NPK treatment. Average wheat and maize yields were 23.7% and 18.0% lower in ON, respectively, and slightly but significantly lower (1.9% and 1.5%, respectively) in 1/2ON than those in NPK. Unbalanced inorganic fertilization without K (NP) was not sustainable for achieving high yields. There was a significant logarithmic relationship between roots and compost input and SOC content in 0\u201320\u00a0cm in 2003. Over the time of the study SOC storage in 0\u201320\u00a0cm increased by 12.2\u00a0Mg C ha \u2212\u00a01 in ON, 7.8\u00a0Mg C ha \u2212\u00a01 in 1/2ON, and 3.7\u00a0Mg C ha \u2212\u00a01 in NPK, and decreased by 1.6\u00a0Mg C ha \u2212\u00a01 in NK and 1.4\u00a0Mg C ha \u2212\u00a01 in CK. Measured dynamics of SOC and model simulation predictions showed that the SOC in NPK, ON and 1/2ON almost reached equilibrium in 2003. These results indicate that although the balanced application of chemical fertilizers of N, P, and K maintains the crop production in the region, it is not an ideal practice from the point view of carbon sequestration in soil. Application of compost alone has a reverse effect on crop yields and carbon sequestration in soil. Therefore, mixed application of organic and inorganic fertilizers is a compromise between food security and soil carbon sequestration in the region.", "keywords": ["2.

Within-location relationships with topographic variables were weak and infrequent relative to those with edaphic and land-use history variables. Soil texture was strongly correlated with soil C at each location, although the relative significance of different particle size fractions differed among locations. Electrical conductivity appeared more widely applicable since it was included in C models at two locations.

Higher plant-labile P (water\u2013Pi\u00a0+\u00a0NaHCO 3 \u2013Pi) corresponded to soils with higher total P, and this was directly related to the increase of organic P (NaHCO 3 \u2013Po\u00a0+\u00a0NaOH\u2013Po).

However forest harvesting may quickly affect soil carbon stocks and dynamics, especially where organic substances drive the soil-forming processes, such as in Podzols. To evaluate the effects of clear cutting on carbon dynamics and podzolisation process over a short time period, a pristine boreal forest (Komi Republic, Russian Federation) and a recently clear cut site (5\u00a0year-old) were selected. Soils are polygenic: podzolisation occurs within the clay-depleted eluvial horizon, formed by a previous lessivage process. Because podzolisation can start only after the eluvial horizon has reached a sort of threshold, bisequal soils allow to individuate comparable pedogenic conditions prior to anthropogenic disturbances. After harvesting, C storage tended to increase in the upper part of the soil profile (organic layer and podzolic sequum) from 2.2 to 5.0\u00a0kg\u00a0m\u2212\u00a02. The abundance of woody materials on the forest floor together with an increase in soil water saturation, discernible by the vegetation survey and iron fractionation, prevented litter degradation and allowed organic matter accumulation at the soil surface. Fulvic acids (FA) in the organic layer of the pristine site showed a low incorporation of polysaccharide and proteinaceous moieties, confirming a higher degradation of the humified fraction than at the clear cut site. The lack of disturbances allowed a selection of FA with the more oxidised and mobile fractions accumulating in the deeper horizons, as currently observed in Podzols. Almost no differences were instead found in the chemical composition of FA along the profile from the clear cut site. A larger portion of FA showed the tendency to migrate through the profile after clear cutting even below the Bhs horizon (C-fulvic acid/C-humic acid >\u00a01) with a marked increase in the FA-carbon stocks with respect to the pristine forest soil (0.66 and 0.30\u00a0kg\u00a0m\u2212\u00a02 down to 30\u00a0cm, respectively). Clear cutting also affected Al and Fe dynamics. The reducing conditions acted upon soil mineral surfaces and enhanced Fe mobilisation probably both in the ionic form and complexed with organic matter. The Al dynamics was instead more related to short term transformations of the layer silicate phases. Traces of a poorly crystalline chlorite were detectable in the Bhs in the pristine forest, but at the clear site only hydroxy-interlayered vermiculite was present. The high amounts of organic acids that migrated through the Bhs after clear cutting may have partially complexed the Al from pedogenic chlorite, giving rise to hydroxy-interlayered behaviour, as normally occurs in Podzol eluvial horizons from where the organic Al-complexes migrate. Our findings suggested that if this trend proceeds further the whole podzolic sequum may migrate downwards. This may have important implication on C budget, as organic carbon will be transferred deeper in the soil profile limiting its losses at least over a short time period.", "keywords": ["BISEQUAL SOILS; CARBON STOCKS; CLAY MINERALOGY; FULVIC ACIDS; NORWAY SPRUCE", "0401 agriculture", " forestry", " and fisheries", "04 agricultural and veterinary sciences", "15.

After 22 years of cropping, a significantly larger amount (P < 0.05) of available phosphorus and exchangeable potassium was found in the surface horizon (0-10 cm) under DD compared with CT, whereas the extractable calcium content was higher in CT (600 mg kg -1 ) than in DD (500 mg kg -1 ). Irrespective of the tillage, the CEC (0.52 mole kg -1 ) had high values, indicating the good fertility level of the soil used in the experiment. The high CEC of this soil related to the presence large amounts of smectitic clay. Even under these conditions, DD can improve fertility levels. In general, the changes in soil chemical properties did not result in significant differences (P < 0.05) in legume yields. However, the evolutions of the mean yields behaved better under DD than with CT, with a higher harvest ratio higher in DD (1.26 Mg ha -1 , 118%) compared with CT (1.07 Mg ha -1 , 100%) and producing approximately 15% more during the period. The DD/CT yield ratio increase as the annual rainfall did, indicating the more efficient water use of DD under dry farming in this soil.", "keywords": ["2.

The aim of this study was to investigate the temporal response of the soil macroorganic fraction to different organic coffee farming practices (e.g., plant residue, earthworm and microbial inocula addition). Three density fractions of macroorganic matter (N150 \u03bcm) were studied during 1 year after adding shade tree (Erythrina poeppigiana) pruning residues to the soil (5 t ha \ufffd1 twice at 6 monthly intervals). Soil macroorganic matter represented only a small proportion of total soil organic matter (SOM) (3\u20136% of total). Even though the total amount of SOM did not change over time, significant temporal changes in the size of the macroorganic fraction were observed that appeared to be largely independent of the management regime. The light density fraction seemed to be the most responsive fraction and this study suggests that it may provide a qualitative indicator of the \u2018active\u2019 fraction of SOM; the size of the macroorganic fraction did not provide a reliable indicator of the rate of litter decomposition or nutrient release. The addition of microbial inoculants and earthworms had only a small and inconsistent effect on macroorganic matter dynamics and these practices appeared to offer little agronomic benefit. This study highlights the need for continued organic matter inputs to maintain soil C reserves and preserve soil organic quality in tropical organic farming systems. \u00a9 2007 Elsevier B.V.

Both variables are prone to changes and are influenced by abiotic and biotic processes. To determine the effect of variations of both variables on SOC stocks at two grassland sites, one with Stagnic Vertisols and one with Orthoeutric Arenosols, 440 soil cores were sampled down to 60cm depth. Bulk density and C and N concentrations were measured in 5cm intervals (0\u201310cm depth) and 10cm intervals (10\u201360cm depth). SOC stocks at the clay rich site with Vertisols were almost twice as high (86t C ha \u2212\u00a01 in 0\u201360cm depth) as at the sandy site with Arenosols (48t C ha \u2212\u00a01 ). Variations in the SOC stocks were determined by the thickness of the loess layer at the clay rich site. Underlying clay horizons hampered the C translocation into the subsoil which resulted in lower SOC stocks of the whole profile. Semivariograms showed spatial autocorrelations of SOC concentrations within a range of 47 and 131m, respectively. The range of autocorrelation between samples of bulk density was much shorter (39 and 51m). Relative variances in bulk density were 1\u20132 magnitudes lower than the variability of SOC concentration and decreased rapidly as soil depth increased. The difference in the variation of SOC concentration and bulk density was used to revise the sampling design for SOC stocks. An unequal number of samples, i.e. more SOC concentration samples than bulk density samples, would not necessarily decrease the power of the sampling design to detect SOC stock changes.

China)", "description": "Abstract It is not clear from the literature whether heavy grazing leads to a deterioration of physical and chemical parameters of topsoils in steppe ecosystems. We sampled five sites in northern China with different grazing intensities, ranging from ungrazed since 1979 to heavily grazed, at 540 sampling points to a depth of 0\u20134\u00a0cm. Each sample was analysed for bulk density, organic carbon (OC), total nitrogen (N), total sulphur (S) and pH. The dataset was analysed using general statistics and explorative analysis (ANOVA, Kruskal\u2013Wallis). As a result of the large number of samples, we were able to detect a change in the mean value of all parameters of less than 10%, with a statistical power of 90% and a level of significance of 0.01. Bulk density increased significantly with increasing grazing intensity. Organic carbon, total N and total S concentrations decreased significantly with increasing grazing intensity. No effect on the pH or C/N ratio was detected. Significant differences in C/S and N/S ratios between differently grazed plots were found. These differences point towards a relative accumulation of sulphur in grazed compared to ungrazed areas following an increased organic matter decline or lower inputs of diluting litter. Elemental stocks of the upper 4\u00a0cm were calculated for OC, total N and total S using the measured bulk densities. The data revealed significantly lower amounts for all three elements on the heavily grazed site, but no significant differences for the other areas. In addition, elemental stocks were calculated using an equivalent mass instead of bulk density to take into account changes in bulk density following grazing. This revealed a highly significant decrease for OC, total N and total S with increasing grazing intensity. OC, total N and total S concentrations respond similarly to different grazing intensities, showing highly significant positive correlations. OC concentrations and bulk densities were significantly negatively correlated. We found effects of grazing cessation only in the long-term, as no ameliorating effects of reduced or excluded grazing could be detected five years after grazing cessation. After 25\u00a0years of exclusion, significantly different values were found for all parameters. Thus, physical and chemical parameters of steppe topsoils deteriorated significantly following heavy grazing, remained stable if grazing was reduced or excluded for five years, and recovered significantly after 25\u00a0years of grazing exclusion.", "keywords": ["2.

While producing renewable energy from biomass is necessary, impacts of harvesting corn stover on soil organic carbon (SOC) sequestration, agricultural productivity, and environmental quality must be also carefully and objectively assessed. We conducted a 2 1/2 year study of stover management in long-term (N8 yr) no-tillage (NT) continuous corn systems under three contrasting soils in Ohio to determine changes in SOC sequestration, CO2 emissions, soil physical properties, and agronomic productivity. These measurements were made on a Rayne silt loam (RSL) (fine-loamy, mixed, active, mesic Typic Hapludult) with 6% slope, Celina silt loam (CSL) (fine, mixed, active, mesic Aquic Hapludalfs) with 2% slope, and Hoytville clay loam (HCL) (fine, illitic, mesic Mollic Epiaqualfs) with b1% slope. Stover treatments consisted of removing 0, 25, 50, 75, and 100% of corn stover following each harvest.

Annual stover removal rate of N25% reduced SOC and soil productivity, but the magnitude of impacts depended on soil type and topographic conditions. Stover removal rate of 50% reduced grain yield by about 1.94 Mg ha \u22121 , stover yield by 0.97 Mg ha \u22121 , and SOC by 1.63 Mg ha \u22121 in an unglaciated, sloping, and erosion-prone soil (Pb0.05). The initial water infiltration rates were significantly reduced by N25% of stover removal on a RSL and CSL. Plant available water reserves and earthworm population were significantly reduced by 50% of stover removal at all soils. Increases in soil compaction due to stover removal were moderate. Stover removal impacts on SOC, crop yield, and water infiltration for HCL were not significant.

Additionally, the potential of hot-water extractable organic matter as an indicator of changes in SOM was also assessed. Significant differences in labile SOM fractions (hot-water extractable organic C and total N, cold-water extractable organic C and total N, and microbial biomass C and N) between pure Cunninghamia lanceolata Hook plantation and native broadleaved forest were tested using ANOVA. The contents of soil organic C, total N, and labile organic matter such as hot-water extractable organic C and total N, cold-water extractable organic C and total N, and microbial biomass was significantly lower in pure C. lanceolata plantation than in native broadleaved forest. The percentage ratios of hot-water extractable organic C and N, cold-water extractable organic C, and microbial biomass C and N to soil organic C or total N were also significantly reduced in C. lanceolata plantation.

Sodium polytungstate (SPT, density=1.6 g mL -1 ) was used to fractionate the soil into light (LF, densityb1.6 g mL -1 ), occluded light (LFo, densityb1.6 g mL -1 ) and heavy fractions (HF densityN1.6 g mL -1 ). The results showed that C and N concentrations (g kg -1 of fraction) in the SOM density fractions decreased in the order of LFoNLFNHF, while the C/N ratio was in the order of LFNLFoNHF. The amount of C and N stored in the LF, LFo and HF fractions and bulk soil in the top 10 cm of soil was: 149-504, 70-336, 1380-2876 and 1617-3776 g m -2 , respectively, for C, and 6-26, 3-20, 149-271 and 152-299 g m -2 , respectively, for N. From 2004 to 2006, C and N storage decreased in the LF and LFo fractions but increased in the HF fraction in the youngest stand. However, stand-age effects were likely muted by high inherent soil variability among the stands. Carbon storage in the light fraction was responsive in the short term to hybrid poplar plantation establishment. \u00a9 2008 Elsevier B.V. All rights reserved.", "keywords": ["2. Zero hunger", "13.

The objective of this research was to characterize carbon (C), net nitrogen (N) and phosphorus (P) mineralization of shrub residues during decomposition in soil beneath or outside shrub canopies. Two lab incubation (30\u00a0\u00b0C for 118\u00a0days) studies (1 for each shrub species/soil type system) had a 2 by 4 factorial design with two soil sources (beneath or outside the shrub canopy) and four residue soil amendments (leaf, leaf\u00a0+\u00a0stem, beef manure, or control of soil only). Soils amended with P. reticulatum or G. senegalensis leaf residues immobilized N during the first 62 and 76\u00a0days, respectively, but later had net release of inorganic N. The addition of stems to leaf amendments for both shrub species resulted in net N immobilization throughout the incubation. Manure had positive but shrub residues negative release of inorganic P. However, if the leached P released at time zero is included in the summation, all amendments released more P than the control. Cumulative net release of C, N or P over the incubation was higher in soil originating from beneath than outside the shrub canopy except for release of P from soil associated with G. senegalensis . Residue chemistry was related to nutrient release, particularly high lignin content of stems, which corresponded to N immobilization.

Longterm no-tillage with straw cover increased SOM by 21.7% and TN by 51.0% at 0\u201310 cm depth and available P by 97.3% at 0\u20135 cm depth compared to traditional tillage. Soil microbial biomass C and N increased by 135.3% and 104.4% with NTSC compared to TTSR for 0\u201310 cm depth, respectively. Under NTSC, the metabolic quotient (CO2 evolved per unit of MBC) decreased by 45.1% on average in the top 10 cm soil layer, which suggests that TTSR produced a microbial pool that was more metabolically active than under NTSC. Consequently, winter wheat yield was about 15.5% higher under NTSC than under TTSR. The data collected from our 16-year experiment show that NTSC is a more sustainable farming system which can improve soil chemical properties, microbial biomass and activity, and thus increase crop yield in the rainfed dryland farming areas of northern China.

In order to assess the retention of eroded C in these settings, SOC stock was measured in grass buffers receiving runoff from cropped watersheds under long-term (>\u00a020\u00a0y): chisel-till (CT) corn ( Zea mays , L.)-soybean [ Glycine max , (L.) Merr.] rotation, moldboard plowing (MP) continuous corn (CC), and no-till (NT) CC. Adjacent reference grasslands not affected by erosion were also sampled. In the CC watersheds, the \u03b4 13 C of bulk soil and soil separates was determined to identify the source of SOC in the grass filters. After accounting for differences in the number of corn crops, SOC stock in the MP watershed showed a corn-C deficit of 9.3\u00a0Mg C ha \u2212\u00a01 compared to NT. Corn-C accounted for 2 to 16% (mean: 5.2\u00a0Mg C ha \u2212\u00a01 ) of the total SOC pool in the grass filter and, assuming water erosion as the main determinant of C distribution, this corn-C gain translates into the retention of 55% of eroded C in the grass strip. Relative to the reference grasslands, SOC stock in the grass filters was up to 30\u00a0Mg C ha \u2212\u00a01 higher, an amount deemed too large to be attributed solely to retention of eroded C (export rate: 0.05-0.08\u00a0Mg C ha \u2212\u00a01 y \u2212\u00a01 ). Periodic delivery of nutrients may have enhanced biomass production and indirectly contributed to the observed SOC accrual in grass filters. Higher extractable P and higher C:N ratios at these locations support that hypothesis. These results demonstrate the applicability of 13 C isotope to trace SOC sources in buffers receiving runoff from areas supporting C 4 vegetation. They also underscore the need to incorporate in-situ biomass production and burial processes in assessing the temporal evolution of SOC stocks in terrestrial deposits and the contribution of these landscape segments to watershed C budget.", "keywords": ["2.

Data on WR for agricultural soils are, however, extremely limited to ascertain the extent of this property. Thus, we assessed the WR in long-term no-till (NT) fields adjacent to plow tillage (PT) and woodlot (WL) and its statistical relationships with SOC concentration, soil particle-size distribution, and aggregate stability across 11 soils distributed in Major Land Resources Areas (MLRAs: 121, 122, and 125 in Kentucky, 99, 124, and 139A in Ohio, and 139B, 139C, 140, 147, and 148 in Pennsylvania) in the eastern US. The WR tended to increase with increasing soil water potential, and management impacts on WR depended on soil water potential. Mean water drop penetration test (WDPT) ranged from 0.5 to 12\u00a0s while water repellency index (R index) ranged from 1.5 to 5 for air-dry aggregates in the surface 0- to 5-cm soil depth. At the same depth, WR in NT was significantly higher than in PT by 1.5 to 6.0 times in 8 out of 11 soils. These soils had weak and very weak water repellency. In MLRA 124, NT had WR 30% higher than PT soil in the 0- to 5-cm depth but had lower WR in lower depths. The SOC concentration explained 28% (P\u00a0<\u00a00.001) of the variations in LogWDPT, which, in turn, explained 45% (P\u00a0<\u00a00.001) of the variations in aggregate stability. The LogWDPT increased with an increase in sand concentration (r\u00a0=\u00a00.44; P\u00a0<\u00a00.001) and decrease in clay concentration (r\u00a0=\u00a0\u2212\u00a00.41; P\u00a0<\u00a00.001). The WDPT was moderately correlated (r\u00a0=\u00a00.39; P\u00a0<\u00a00.05) with R index.

Capillary electrophoresis was employed for the quantification of monosaccharides and phenolic compounds, whereas NMR and FT-IR were used for the overall characterization of the soils organic matter. Application of farmyard manure results in a higher content of organic matter derived from angiosperms, suggested by the higher levels of syringic and vanillic phenols. Spectroscopic studies show an increase of lignin and lignin-like products in the organic matter of the soil, which may be derived from the cereal straw supplied with farmyard manure. According to spectroscopic analysis, 13 C CPMAS-NMR and FT-IR spectra, higher contents of methylene groups (- CH2) from proteins and protein-like compounds, as well as higher levels of carbohydrates, were found in the soil supplied with compost. The monosaccharide (rhamnose, xylose, glucose, mannose, arabinose, fucose and galactose) content was not significantly influenced by the different organic fertilizers, suggesting that the type of amendment used does not affect any of these six studied monomers. Comparing the three organic amendments the most significant differences were observed after long-term application of farmyard manure, with an increase in lignin and lignin-like products in the soil organic matter, and compost, which appears to contribute to an increase of protein and protein-like, as well as carbohydrates content on soil organic matter.

Improved grassland management on Oxisols increased SOC storage by 1.19\u00a0\u00b1\u00a00.07, relative to native stocks, but there were insufficient data to evaluate the impact of improved grassland management for other soil types. Using these results, we also evaluated the potential for grassland management to sequester or emit C to the atmosphere, and found that degraded grassland management decreased stocks by about 0.27\u20130.28\u00a0Mg C ha \u2212\u00a01 yr \u2212\u00a01 ; nominal management on Oxisols decreased C at a rate of 0.03\u00a0Mg C ha \u2212\u00a01 yr \u2212\u00a01 , while nominal management on others soil types and improved management on Oxisols increased stocks by 0.72\u00a0Mg C ha \u2212\u00a01 yr \u2212\u00a01 and 0.61\u00a0Mg C ha \u2212\u00a01 yr \u2212\u00a01 , respectively. Therefore, when well managed or improved, grasslands in Rondonia and Mato Grosso states have the potential to sequester C.", "keywords": ["2.

The objective of this study was to evaluate the soil carbon (C) and nitrogen (N) contents in different soil organic matter (SOM) pools (light and heavy fractions), the role of light- and heavy-fraction C in SOC sequestration, and culturable microbial counts in the surface (0\u201320\u00a0cm) of a fluvo-aquic soil after 18\u00a0years of fertilization treatments under a wheat\u2013maize cropping system in the North China Plain. The experiment included seven treatments: (1) OM, organic manure; (2) 1/2OMN, half organic manure with mineral fertilizer NPK; (3) NPK, mineral fertilizer NPK; (4) NP, mineral fertilizer NP; (5) PK, mineral fertilizer PK; (6) NK, mineral fertilizer NK; and (7) CK, unfertilized control. Carbon and N contents of the light and heavy fractions were highest in the OM treatment, while the CK treatment showed the lowest value. Application of half organic manure with mineral fertilizer NPK (treatment 2) significantly increased C and N contents of the light and heavy fractions in soil in comparison with application of mineral fertilizer alone (treatments 3, 4, 5, and 6). For the mineral fertilizer treatments, a balanced application of NPK (treatment 3) showed higher C and N contents of the light and heavy fractions than an unbalanced use of fertilizers (treatments 4, 5, and 6). Heavy-fraction C dominated total SOC storage in all treatments. The total SOC increase under fertilization treatments is attributed to an increase in C content of both the light and the heavy fraction. However, the SOC increase for the manure treatments was mainly due to an increase in the C content of the heavy fraction, whereas that for mineral fertilizer treatments was mainly due to an increase in the C content of the light fraction. The total soil culturable microbial counts (including bacteria, fungi, and actinomycetes) was observed to be highest for the OM treatment, while the control plot showed the lowest value. Application of half organic manure with mineral fertilizer NPK was found to produce a higher culturable microbial counts than application of mineral fertilizers alone, and the NPK treatment gave a higher culturable microbial counts than other mineral fertilizer treatments (NP, PK or NK). Light-fraction C is probably the better predictor of microbial abundance, as it correlated more strongly with culturable microbial counts than total SOC did.", "keywords": ["2.

The results revealed that long-term GE had a marked impact on soil particle-size fractions and their total C and N concentrations. The C associated with sand and clay in the 0\u201310\u00a0cm soil layer exhibited a significant logarithmic increase as period of GE increases. The increase in C storage with the introduction of GE was considerable, especially in the sand and clay fraction of 0\u201310\u00a0cm soil layer.

Considering the accumulation of total C in the whole soil and soil fractions and their logarithmic increase during the GE chronosequence, we suggest that by implementing GE, the temperate grasslands of northern China could facilitate significant C storage on decade scales; however, when subjected to GE for 2 decades or more, these grassland soils would have a lower potential to further accumulate the C newly derived from litter and dead roots.", "keywords": ["2.

Soil C/N and net N-mineralization are commonly reported empirical measures of soil N availability, and changes in these variables due to N inputs may feed back to soil C storage through a variety of biotic and abiotic pathways. We conducted a meta-analysis of the responses of soil C storage, C/N, and net N-mineralization (Nmin) to N inputs in north temperate forests. The modes of N addition we considered were the establishment of N-fixing vegetation (Nfix), N-fertilization (Nfert), and simulated chronic N deposition (Ndep).

C/N shifts were restricted to the forest floor (\u22127.8%), whereas forest floor and mineral soil Nmin responses to N inputs were very similar (+61% and +64%, respectively). Significant between-study variation in the effects of N inputs on soil parameters was related to the mode of N addition, biogeographic factors, and time.

Rates of ecosystem processes such as decomposition are likely to change as a result of human impacts on the environment. In southern California, climate change and nitrogen (N) deposition in particular may alter biological communities and ecosystem processes. These drivers may affect decomposition directly, through changes in abiotic conditions, and indirectly through changes in plant and decomposer communities. To assess indirect effects on litter decomposition, we reciprocally transplanted microbial communities and plant litter among control and treatment plots (either drought or N addition) in a grassland ecosystem. We hypothesized that drought would reduce decomposition rates through moisture limitation of decomposers and reductions in plant litter quality before and during decomposition. In contrast, we predicted that N deposition would stimulate decomposition by relieving N limitation of decomposers and improving plant litter quality. We also hypothesized that adaptive mechanisms would allow microbes to decompose litter more effectively in their native plot and litter environments. Consistent with our first hypothesis, we found that drought treatment reduced litter mass loss from 20.9% to 15.3% after six months. There was a similar decline in mass loss of litter inoculated with microbes transplanted from the drought treatment, suggesting a legacy effect of drought driven by declines in microbial abundance and possible changes in microbial community composition. Bacterial cell densities were up to 86% lower in drought plots and at least 50% lower on litter derived from the drought treatment, whereas fungal hyphal lengths increased by 13\uffe2\uff80\uff9314% in the drought treatment. Nitrogen effects on decomposition rates and microbial abundances were weaker than drought effects, although N addition significantly altered initial plant litter chemistry and litter chemistry during decomposition. However, we did find support for microbial adaptation to N addition with N\uffe2\uff80\uff90derived microbes facilitating greater mass loss in N plots than in control plots. Our results show that environmental changes can affect rates of ecosystem processes directly through abiotic changes and indirectly through microbial abundances and communities. Therefore models of ecosystem response to global change may need to represent microbial biomass and community composition to make accurate predictions.
