However, the effects of N and P additions on nitrification and denitrification processes in <i>Metasequoia glyptostroboides</i> plantations, and economically important forest type in China, remain poorly understood.<h4>Methods</h4>This study investigated the responses of soil nitrification and denitrification rates, as well as the abundances of nitrifiers and denitrifiers, to different levels of N and P additions in a 6-year nutrient addition experiment in a <i>M. glyptostroboides</i> plantation.<h4>Results</h4>Stepwise multiple regression analysis was used to identify the main predictors of nitrification and denitrification rFrontiers in plant science1448356https://www.ebi.ac.uk/biostudies/studies/S-EPMC11384580biostudies-literatureNitrogen and phosphorus additions alter soil N transformations in a Metasequoia glyptostroboides plantation.PMC11384580Wu MShao XGuo YZhang YWu TXu HYuan WJiang PLi NfalseNitrogen and phosphorus additions alter soil N transformations in a Metasequoia glyptostroboides plantation.<h4>Introduction</h4>Nitrogen (N) and phosphorus (P) enrichment due to anthropogenic activities can significantly affect soil N transformations in forest ecosystems.
