High plant diversity alleviates the negative effects of nitrogen deposition on soil nitrogen cycling multifunctionality.

ABSTRACT:

Introduction

Changes in plant diversity and increased atmospheric nitrogen deposition independently influence soil nitrogen cycling in terrestrial ecosystems. However, the interactive effects of plant diversity and nitrogen deposition on soil nitrogen cycling multifunctionality (NCMF) in grassland ecosystems remain poorly understood.

Methods

We conducted a fully factorial microcosm experiment to quantify the responses and underlying mechanism of soil NCMF to nitrogen addition (0, 5, and 10 g N m^-2 yr.^-1) and plant diversity gradients (1, 3, and 6 species).

Results

Our results revealed a significant interactive effect between plant diversity and nitrogen addition on soil NCMF. Specifically, high plant diversity alleviated the negative effects of n
