Summary: This study aimed to assess the fertilizing effects of digestate on soil properties. The results showed that digestate not only contains essential nutrients for crops but also can alter the biogeochemical cycle of nutrients and soil functionality. However, at high doses, digestate application negatively affected soil enzyme activities, microbial biomass, and soil P and C cycling capacity.

Summary: The study found that crops sown on November 17 had the highest levels of bacteria, fungi, actinomycetes, soil microbial biomass carbon, dehydrogenase activity, and available nitrogen, phosphorus, potassium, and sulphur. When using nutrient sources, the combination of 75% recommended dose of fertilizers, 25% nitrogen from pressmud, Azotobacto, and phosphorus solubilizing bacteria showed the highest microbial population and nutrient content.

Summary: This study conducted two experiments with sandy loam soil to investigate the influence of water content changes on soil respiration and nutrient availability. Results showed that microbial biomass nitrogen decreased after rewetting in previously moist soils, while it increased in previously dry soils. Additionally, available nitrogen levels changed significantly in response to different water content treatments.

Summary: Vermicomposting of bakery sludge with the addition of fruit-vegetable waste and cow dung improved the quality of the sludge. The pH decreased, total organic carbon decreased, and electrical conductivity, ash content, nitrogen, phosphorus, and potassium increased after vermicomposting. Among the different ratios of waste and dung, VU3 showed the best results, with the highest seed germination rate. The addition of fruit-vegetable waste also enhanced the population and growth rate of earthworms.

Summary: This study found that precipitation history has an impact on the microbial community's response to rewetting, which is related to the nitrogen status. Regardless of precipitation or nitrogen input history, active bacteria showed a small shift in community composition within 1 hour of rewetting, but did not change further for the remaining 28 hours analyzed. Active fungi did not respond to rewetting within 29 hours. These findings are important for understanding the short-term response of soil microbial communities and their effects on food web stability and soil biogeochemical cycling.

Summary: Grassland management practices, particularly multi-paddock grazing, can impact the composition of soil microbial communities. This study found that multi-paddock grazing resulted in alterations to the microbial biomass and ratios of functional groups in grassland soils compared to conventional grazing.

Summary: Positive Priming Effect is defined as the acceleration of soil organic matter decomposition by fresh organic matter input. Its impact depends on the nature of the targeted organic matter pool and the ratio between the incorporation of primed carbon into microbial biomass and its mineralization.

Summary: The study revealed that substrate quality had a greater impact on soil microbial activities, with soil respiration and microbial biomass increasing after substrate addition. The association between high NO3-N concentration and low microbial biomass suggested increased microbial C turnover due to C exhaustion. Different substrates had varying effects on enzyme activities.

Summary: Many studies have been conducted on the responses of soil CO2 emissions to altered supplies of C and N, but limited information exists on P. This study evaluated the response patterns of CO2 emissions to alkalinity and nine elements in soils, and also investigated changes in DOC, MBC, and microbial structure. The results showed that different nutrients had different effects on CO2 emissions and microbial activity. This study highlights the complexity of predicting soil processes and the need for further research on the interactions in forest soils.

Summary: Global climate warming has no significant effect on soil carbon (C) stock, but it can increase root biomass and soil respiration, depending on soil nitrogen (N) availability. The availability of soil C to N critically mediates warming effects on soil C dynamics, and incorporating this into C-climate models may improve the prediction of soil C cycling under future global warming scenarios.

Summary: Application of phosphorus and potassium fertilization in integrated crop-livestock systems has a direct impact on the microbial community and biomass, affecting carbon and nitrogen availability, but does not increase rice yield. Soybean-rice rotation in integrated crop-livestock systems yields more than rice monocropping, with soil bacteria being more sensitive to changes in soil nutrient status during flooding period than saprophytic fungi.

Summary: Biocrusts play a significant role in soil organic carbon processes in drylands, and the predicted increase in aridity will impact soil organic carbon dynamics. In this study, microbial respiration and its temperature sensitivity were measured in bare soil and two types of biocrusted soils in northern China's dryland. The results showed that biocrusts positively influenced microbial respiration and had a negative impact on the temperature sensitivity, which increased with decreasing precipitation. These findings highlight the importance of expanding biocrust cover in maintaining soil organic carbon stability in response to climate warming.

Summary: Intensive mono-cropping without balanced nutrient supply and decreasing water resources are degrading soil health, leading to unsustainable agricultural production and environmental degradation. Results showed that restricting irrigation and using integrated nutrient sources improved root growth, soil microbial biomass carbon, and enzyme activity in wheat production.

Summary: The study demonstrated that the type of organic mulch used can affect the availability of nutrients and respiration rate in soil, with wheat straw enhancing nitrogen immobilization and reducing nitrogen leaching from faba bean mulch. The microbial biomass nitrogen was significantly higher in soil mixed with wheat and mulched.
