Nitrogen and phosphorus additions alter soil N transformations in a Metasequoia glyptostroboides plantation.

ABSTRACT:

Introduction

Nitrogen (N) and phosphorus (P) enrichment due to anthropogenic activities can significantly affect soil N transformations in forest ecosystems. However, the effects of N and P additions on nitrification and denitrification processes in Metasequoia glyptostroboides plantations, and economically important forest type in China, remain poorly understood.

Methods

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 M. glyptostroboides plantation.

Results

Stepwise multiple regression analysis was used to identify the main predictors of nitrification and denitrification r
