Different responses of soil fungal and bacterial communities to nitrogen addition in a forest grassland ecotone.

ABSTRACT:

Introduction

Continuous nitrogen deposition increases the nitrogen content of terrestrial ecosystem and affects the geochemical cycle of soil nitrogen. Forest-grassland ecotone is the interface area of forest and grassland and is sensitive to global climate change. However, the structure composition and diversity of soil microbial communities and their relationship with soil environmental factors at increasing nitrogen deposition have not been sufficiently studied in forest-grassland ecotone.

Methods

In this study, experiments were carried out with four nitrogen addition treatments (0 kgN·hm^-2·a^-1, 10 kgN·hm^-2·a^-1, 20 kgN·hm^-2·a^-1 and 40 kgN·hm^-2·a^-1) to simulate nitrogen deposition in a
