Summary: This study investigates the implications of permafrost thaw on forest soil Nmin in a hemiboreal forest. The results show that permafrost thaw significantly decreases Nmin values. Nmin is positively associated with soil substrates, microbial biomass, and soil moisture content. The decline in Nmin is primarily attributed to changes in soil substrates rather than plant community composition.

Summary: The study aimed to investigate the effects of organic fertilizer derived from food waste on N mineralization, microbial biomass, and enzyme activities in paddy soil. The experiment showed that organic fertilization increased N mineralization, microbial biomass, and enzyme activities in soil aggregates. These findings provide important insights for food waste recycling, sustainable agricultural practices, and paddy soil N management.

Summary: The study aimed to develop a simple model for SOM N mineralization, test and validate its applicability, and investigate its potential use in adjusting commercial N fertilizer recommendations. Results showed that the model predictions were close to observed values and could be used for refining nitrogen fertilizer recommendations.

Summary: Soil microbial community composition is influenced by exogenous organic matter and plays a vital role in organic matter decomposition. However, studies on the combined effect of crop residues and pig manure on soil microbial community and enzyme activities are limited. A greenhouse pot experiment was conducted to investigate the potential effect of exogenous organic matter on soil properties, enzyme activities, and microbial communities. The results showed that the addition of rice straw significantly increased microbial biomass, carbon and nitrogen contents, as well as cellulase and beta-1,4-glucosidase activities, regardless of pig manure addition. Moreover, the interaction between crop residues and pig manure had a significant impact on microbial biomass nitrogen and phosphorus contents, as well as the ratio of gram-positive bacteria to gram-negative bacteria. Pig manure application not only provided abundant nutrients but also enhanced microbial and enzymatic activity compared to no pig manure addition. The combination of above-ground straw and pig manure is a better option for improving soil ecosystem functions.

Summary: The sensitivity of C and N mineralization to water potential in soil varies significantly between sites, and can be accurately predicted by specific soil properties. This suggests the potential for improving soil and soil-crop models to better predict water stress on C and N mineralization, particularly in the context of climate change.

Summary: Calcium plays a crucial role in mediating interactions between organic compounds and minerals in soil. It affects microbial adhesion and colonization of plant and mineral surfaces, and also contributes to the transformation of organic matter in soil.

Summary: The mineralization of soil organic matter is closely related to climate change, with labile organic matter, microbial community, and soil aggregate size playing important roles in this process. Different soil aggregates treated with long-term non-fertilizers, chemical fertilizers, and animal manure were studied for their impact on dissolved organic matter, beta-glucosidase activity, and microbial community composition. The study found that soil aggregate size, DOM concentration, and microbial community composition all affect the mineralization of organic matter.

Summary: The study found limited varietal differences in total biomass or N uptake across different soil environments. Soil organic matter was an important, additive N source regardless of N fertilizer availability. Under low SOM availability, high fertilizer addition increased overall N uptake from SOM by 42% compared to low N fertilizer treatment.

Summary: This study compares two stabilization methods of sewage sludge and their effects on soil organic carbon, microbial biomass and activity, as well as nitrogen and phosphorus availability and maize yield. The results show that the chemical stabilization method (CSS) is more effective in degrading soil carbon and phosphorus, and promoting the rapid release of nutrients, leading to higher maize yield.

Summary: Organic fertilizers and microbial fertilizers play an important role in the transition from conventional fertilizer-to-food chain, especially when produced on secondary resources. This study explores three promising types of microbial fertilizers and finds their potential application value, including adjusting nutrient release, promoting plant growth, and enhancing crop disease resistance.

Summary: The study found that microbial communities in Hadal trenches exhibit high similarity within each trench axis and are strongly influenced by sediment depth and redox stratification. Differences in community composition are more related to sediment depth within each trench rather than between different trenches, and not solely explained by total organic carbon content.

Summary: This study compares the effects of different plant communities on soil organic carbon, nitrogen, and phosphorus mineralization in an alpine meadow. The results show that under shrubs, the rates of nitrogen and phosphorus mineralization in soil are significantly higher, while the increase in organic carbon mineralization is smaller. Furthermore, the decoupling of organic carbon and nutrient mineralization is driven by microbial stoichiometry.

Summary: Soil carbon sequestration (SCS) refers to the uptake of carbon from the atmosphere and its storage in soil, with soil microbial community (SMC) playing a crucial role. Agricultural practices that improve SCS can alter SMC, soil organic matter, and soil aggregates. However, more research is needed to fully understand their contribution to SCS.

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.
