- W3040471510 abstract "The application of exogenous organic matter is considered the main method of increasing the organic matter content of acidic red soils. Nitrogen is an important limiting factor for soil fertility. Changes to the soil ecosystem under organic matter promotion can affect soil nitrogen cycling and related functional microorganisms; however, there have been no studies on this aspect. Acidic upland red soils, with or without long-term organic fertilizer application, were chosen as the research materials in this study. Based on metagenomic sequencing and alignment in the nitrogen-cycling gene database, the present study aimed to investigate the effect of organic matter promotion on nitrogen-cycling genes and functional microorganisms in acidic red soils, which had been amended with exogenous organic matter for 32 years. The results showed that organic matter promotion in acidic soils increased the total organic carbon and total nitrogen content, and alleviated soil acidification. Organic matter promotion increased the soil net nitrification activity and potential for ammoxidation. Organic matter promotion increased the abundance of amoA genes (encoding ammonia monooxygenase) and nar, nap, nir, nor, and nos genes (encoding denitrification reductase); decreased the abundance of hao genes (encoding hydroxylamine oxidase) and nrf genes related to the dissimilatory nitrate reduction to ammonia; increased the abundance of glnA, gdh, glsA, ansB, and nao genes related to organic nitrogen metabolism; altered the abundance of functional genes related to assimilatory nitrate reduction; and changed the community composition of nitrogen-cycling microorganisms. After organic matter promotion, alleviation of soil acidification and enhancement of total organic carbon were the most important factors that affected the abundance of nitrogen-cycling genes and the community composition of functional microorganisms. Our results comprehensively investigated the inorganic and organic nitrogen-cycling genes, and correlated the functional genes, microbial populations, and functional activities in the ammonia oxidizing process, which provided supporting data to understand the nitrogen-cycling characteristics of acidic red soils and provided ideas for acidic soil improvement." @default.
