Influence of land-use types on soil microbial communities and nutrient changes in Xinyang City, China.

ABSTRACT: Soil microorganisms are essential for sustaining ecosystem functions, driving biogeochemical cycles, and modulating carbon storage. However, the nutrient-mediated mechanisms by which different land-use types shape soil microbial communities remain unclear. This study investigated three typical land-use types-plantation, grassland, and high-standard cropland-in Xinyang City, China, to evaluate their effects on soil microbial community. Results showed that soil nutrient contents-including total nitrogen, total phosphorus, alkaline-hydrolyzable nitrogen, and available phosphorus-as well as microbial alpha diversity indices, were consistently higher in topsoil than in subsoil and more pronounced in plantation than in grassland and cropland.
