Summary: This study aimed to investigate the association between changes in microbial community composition and nitrogen mineralization from crop residues in the rhizosphere. Through the cultivation of soybean and maize, along with microbial community sequencing and measurement of nitrogen mineralization, it was found that nitrogen mineralization from soybean residues was faster in the rhizosphere. This could be attributed to the enrichment of ammonification genes, which enhanced the mineralization of soybean residue nitrogen in the rhizosphere.

Summary: The addition of biochar can increase soil pH, SOC content and recalcitrant carbon pool, and increase the activity of N and P cycling enzymes and oxidases. The combination of biochar with N fertilizer can reduce the mineralization rate of SOC and the metabolic quotient, and change the composition of soil microbial community. This is of great significance for soil carbon sequestration and sustainable development of vegetable fields.

Summary: The application of fertilizer in paddy fields has a significant impact on soil bacteria, which in turn affects soil enzyme activities and rice growth. This study investigated different fertilizer treatments and their effects on soil bacteria, enzyme activities, and nutrient loss in paddy soil. The results showed that reducing fertilizer application can affect soil pH, TN, TP, SOM, and bacterial community composition. The IT + RF 10 treatment, with a 10% reduction in nitrogen fertilizer, was found to be the most effective in reducing nutrient loss and promoting soil enzyme activity.

Summary: The chemical composition of cactus forage creates a favorable environment for microbial activity when exposed to air. The exposure of mixtures of cactus forage with buffel grass hay to air increases the proliferation of microorganisms with pathogenic potential in the diet. The study suggests limiting the exposure time to fewer than six hours and using a lower proportion of cactus forage in the diet to minimize the levels of pathogenic microorganisms.

Summary: This study measured the gross N mineralization rate (GNMR) and related properties in an alpine meadow under chronic nitrogen (N) addition at different soil depths. The results showed that GNMR was negatively correlated with N addition rate and soil available NO3- content, and positively correlated with soil pH and carbon/nitrogen ratio (C/N). Acidification, increased N availability, and C limitation all decreased soil N mineralization, with acidification dominating in the topsoil and C limitation dominating in the subsoil. These findings improve our understanding of soil N mineralization with chronic N enrichment at different depths.

Summary: The objective of this study is to incorporate soil hydraulic properties into the erodibility factor (K) of USLE-type models. By modifying and improving the existing equations for soil texture and permeability, the study successfully included information on saturated hydraulic conductivity (Ksat) into the calculation of K factor. Using the Random Forest machine learning algorithm, two independent K factor maps with different spatial resolutions were generated. The results show that the decrease in K factor values has a positive impact on the modeling of soil erosion rates.
