The objectives of this study were to determine the impacts of tillage on soil microbial biomass, mineralized C and N, and soil organic C (SOC) and N (SON) contents for different cotton (Gossypium hirsutum L.) cropping systems in a south-central Texas silt loam soil. Tillage influenced SOC and SON, but most effects were observed at 0\u20135\u00a0cm rather than 5\u201315\u00a0cm. Reduced tillage (RT) in a continuous cotton monoculture increased SOC by 24% and SON by 27% compared to conventional tillage (CT) at 0\u20135\u00a0cm, but tillage had no effect at 5\u201315\u00a0cm. Crop rotation increased soil C and N contents compared to continuous cotton, as a cotton-corn (Zea mays L.) rotation under CT increased SOC by 28% and SON by 26% at 0\u20135\u00a0cm compared to CT continuous cotton. Soil organic C and SON were both 18% greater for cotton-corn than continuous cotton at 5\u201315\u00a0cm. For the 0\u201315\u00a0cm depth interval, the CT cotton-corn rotation increased SOC by an average of 518\u00a0kg\u00a0C\u00a0ha\u22121\u00a0year\u22121 and SON by 57\u00a0kg\u00a0N\u00a0ha\u22121\u00a0year\u22121 compared to CT continuous cotton. Cotton under RT sequestered 254\u00a0kg\u00a0C\u00a0ha\u22121\u00a0year\u22121 and 33\u00a0kg\u00a0N\u00a0ha\u22121\u00a0year\u22121 more than cotton under CT. Reduced tillage increased soil microbial biomass C (MBC) by an average of 11 and 18% compared to CT continuous cotton and the cotton-corn rotation, respectively, while microbial biomass N (MBN) for RT was 62% greater than for CT. Tillage decreased mineralized C and N at both depth intervals, while cotton-corn showed higher mineralized C than continuous cotton. Soils for cropping systems that sequestered the most C and N also had the highest microbial biomass and mineralized C and N, indicating close relationships between microbial activity and soil C and N sequestration. Beneficial effects of RT and intensive cropping were enhanced soil C and N sequestration rates and potentially lower N fertilizer requirements for crops.", "keywords": ["Carbon sequestration", "2.

However, it remains unclear if grazing exclusion can improve ecosystem services related to carbon (C) and nitrogen (N) sequestration in grassland ecosystems. We investigated the effects of 11\u00a0years of grazing exclusion on plant biomass and diversity, soil properties (pH, soil water content (SWC), bulk density (BD), soil organic carbon (SOC), total nitrogen (TN), and C/N ratio), and the C and N stocks of plants and soils in a desert grassland of Northwest China. Grazing exclusion improved plant aboveground biomass and diversity, as well as SWC, SOC, and TN contents, but lowered the belowground biomass, root/shoot ratio, pH, and BD. Moreover, grazing exclusion strongly influenced the C and N stocks of the ecosystem, and the annual mean ecosystem C and N sequestration rates were 0.47 and 0.09\u00a0Mg\u00a0ha \u2212\u00a01 \u00a0yr \u2212\u00a01 , respectively, over 11\u00a0years of grazing exclusion. Soil C stocks were most dynamic in the top 30\u00a0cm of the soil, and N stocks mainly changed in the top 20\u00a0cm after grazing exclusion. Our results indicated that grazing exclusion is an effective measurement on improving the ecosystem C and N pools in desert steppe of Northwest China.", "keywords": ["SOIL ORGANIC C", "0106 biological sciences", "Carbon Sequestration", "550", "MICROBIAL-COMMUNITY", "SPATIAL VARIABILITY", "PHYSICAL-PROPERTIES", "Soil Science", "01 natural sciences", "Soil Prosperities", "CENTRAL ARGENTINA", "CARBON STORAGE", "PLANT-COMMUNITIES", "Vegetation Characteristics", "580", "2.

However, knowledge of their effect on soil organic carbon (SOC) and total nitrogen (TN) concentrations and stocks is still limited. The study was undertaken to evaluate the effects of ICLS under two tillage and fertilization regimes on SOC and TN concentrations and stocks in the 0\u201330\u00a0cm soil layer, in comparison with continuous crops or pasture. The following soil management systems were studied: continuous pasture; continuous crop; 4 years\u2019 crop followed by 4 years\u2019 pasture and vice-versa. The adjacent native Cerrado area was used as a control. Under the rotation and continuous crop systems there were two levels of soil tillage (conventional and no-tillage) and fertility (maintenance and corrective fertility). The stock calculations were done using the equivalent soil mass approach. The land use systems had a significant effect on the concentrations of SOC and TN in the soil, but no effect was observed for the soil tillage and fertilizer regimes. For these two latter, some significant discrepancies appeared in the distribution of SOC and TN concentrations in the 0\u201330\u00a0cm layer. Carbon storage was 60.87\u00a0Mg\u00a0ha \u22121  under Cerrado, and ranged from 52.21\u00a0Mg\u00a0ha \u22121  under the ICLS rotation to 59.89\u00a0Mg\u00a0ha \u22121  with continuous cropping. The decrease in SOC stocks was approximately 8.5 and 7.5\u00a0Mg\u00a0ha \u22121 , or 14 and 12%, for continuous pasture and ICLS respectively. No-tillage for 10 years after the conversion of conventional tillage to no-tillage under the continuous crop system, and 13 years of conventional tillage in continuous cropping did not result in significant changes in SOC stocks. The SOC and TN stocks in surface layers, using the equivalent soil mass approach rather than the equivalent depth, stress the differences induced by the calculation method. As soil compaction is the principal feature of variability of stocks determinations, the thickness should be avoid in these types of studies.", "keywords": ["Carbon and nitrogen sequestration", "Crop-pasture rotation", "2.
