Summary: The study found that the application of organic manure significantly increased the concentrations of SOC and active carbon fractions in soil aggregates, compared to chemical fertilizer treatments. The results also showed that organic manure application played a positive role in promoting the formation of soil macroaggregate structure.

Summary: The study found that no-tillage (NT) and reduced tillage (RT) practices significantly increased soil organic carbon (SOC) fractions, especially those related to soil biological activities. Soil depth and mean annual temperature were identified as the dominant factors affecting the changes in SOC fractions under NT practices.

Summary: This study investigated microbial C use efficiency (CUE) and turnover at different soil depths along an elevational gradient in a subtropical forest. The results showed that microbial CUE increased with elevation in the subsoil, while it was not affected by elevation in the topsoil. The increase in CUE with elevation was mainly driven by microbial growth.

Summary: The widespread use of plastic film in agriculture has led to the accumulation of residual plastic film in the soil, mostly in the form of microplastics. The effects of different film mulching methods on soil ecosystems are not well-studied.

Summary: Microbial biomass and electron acceptors like iron oxides play crucial roles in regulating soil organic carbon (SOC) mineralization in paddy soils. Iron oxides increased CO(2) emissions from SOC, while acetate addition decreased SOC mineralization. Changes in microbial biomass affected CO(2) emissions from both acetate and SOC, highlighting the importance of microbial communities in the carbon cycling of anaerobic paddy soils.

Summary: In the study of tillage practices in the Mollisols region of Northeast China, it was found that strip tillage (ST) has similar soil properties to no tillage (NT), with strip tillage between rows (BR) showing better soil quality and higher organic carbon content at a depth of 0-20 cm compared to NT. Additionally, strip tillage has advantages in improving soil conditions of seedbed.

Summary: This study revisits the quantitative contribution of microbial necromass to the soil organic carbon (SOC) pool by considering the stoichiometric differences of microbes and the full range of the microbial necromass proportion in soil. The results show that the potential contribution of microbial necromass to SOC pool is controlled by the stoichiometry of microbes and soil.

Summary: Long-term shallow tillage has degraded soil structure and hindered maize yield increase in Eastern Inner Mongolia. This study aimed to identify optimal tillage practices for high maize yield. The results showed that strip cultivation and deep ploughing were optimal for Chifeng and Xingan, while subsoiling and deep ploughing were optimal for Tongliao and Hulun Buir.

Summary: This study examines the effects of different sources of organic matter and soil moisture on soil chemical and biological properties. The results show that organic treatments, particularly biochar, significantly increase soil organic matter and microbial biomass carbon. Biochar has a greater impact on soil parameters due to its higher carbon content.

Summary: This meta-analysis investigates the effects of BMPs on soil health within organic farming systems, showing significant improvements in SOC and MBC concentrations. Organic amendments and conservation tillage practices have positive impacts on soil health, while cover cropping can increase SOC concentrations significantly after 5 years.

Summary: Aggregate stability is commonly used to assess soil health, but there are multiple methods available for measurement. This study evaluated four commonly used methods and found moderate correlations among them. The methods were also sensitive to differences in climate and soil properties. None of the methods detected significant effects from rotation diversity or crop count, but all methods detected increased stability resulting from reduced tillage.
