Summary: The addition of plant root residue can efficiently promote microbial residue accumulation and produce a higher proportion of microbial residue in SOC in low fertility soil, while crop residue addition is more conducive to bacterial residue accumulation in high fertility soil. Soil organic carbon sequestration is influenced by the type of crop residue added and the soil fertility conditions.

Summary: The study found that straw residue is mainly retained in soil as particulate organic carbon (POC) and during decomposition, POC significantly increased while dissolved organic carbon (DOC) decreased. The addition of straw residue decreased the complexity of the bacterial microbial network but increased the complexity of the fungal network in IF and IFM treatments.

Summary: This study found that straw incorporation and nitrogen input can improve soil organic matter content, soil macroaggregate stability, and microbial diversity. In the wheat-maize-soybean relay strip intercropping system, SI+N30 was shown to be the most effective way to maintain soil fertility and reduce nitrogen fertilizer use.

Summary: The fine-crush straw returning technique accelerates the decomposition rate of straw by shortening the length of straw pieces, leading to increased dry matter accumulation rate of maize seedlings and improved soil conditions. This new agronomic technology may offer a solution to promote straw returning in maize-growing areas of Northeast China.

Summary: Land-use practices and climatic conditions can alter soil organic carbon content and influence soil microorganisms. Crop residue incorporation has the potential to mitigate carbon losses and promote microbial diversity. A glasshouse experiment was conducted to investigate microbial functional diversity and activity with straw amendments in arable and grassland soils. The gene expression related to organic matter degradation differed between land-use systems, with straw addition enhancing gene expression in arable soils. After one month, arable soils showed similar patterns to grasslands. The findings suggest that amendments can increase microbial diversity in low organic carbon arable soils and promote soil carbon sequestration in grasslands.

Summary: The composition and distribution of organic matter in saline soil are largely unknown. A field experiment was conducted to investigate the effects of straw and nitrogen addition on soil organic matter characteristics. The results showed that the addition of straw and nitrogen significantly increased soil organic matter content and amino sugar contents.

Summary: This study investigated the effects of ridge tillage and plastic film or straw mulching on yield stability, soil water storage, nitrogen budget, and soil nitrogen and organic carbon contents in rain-fed spring maize on the Loess Plateau. The results showed that plastic film mulching increased maize yield and stability, improved water use efficiency, and maintained soil nitrogen and organic carbon contents. However, the potential impact of microplastic contamination should be considered.

Summary: Subsoiling combined with straw mulching can improve soil sustainability, increase soil moisture capacity and hydraulic conductivity. Compared to conventional tillage with straw mulching, subsoiling with straw mulching has more significant effects on improving soil physical properties and organic carbon content.
