Effects of stand age and soil microbial communities on soil respiration throughout the growth cycle of poplar plantations in northeastern China.

ABSTRACT:

Introduction

Many studies have identified stand age and soil microbial communities as key factors influencing soil respiration (Rs). However, the effects of stand age on Rs and soil microbial communities throughout the growth cycle of poplar (Populus euramevicana cv.'I-214') plantations remain unclear.

Methods

In this study, we adopted a spatial approach instead of a temporal one to investigate Rs and soil microbial communities in poplar plantations of 15 different ages (1-15  years old).

Results

The results showed that Rs exhibited clear seasonal dynamics, with the highest rates observed in the first year of stand age (1-year-old). As stand age increased, Rs showed a significant decreasing trend. We further identified r-selected microbial communities (copiotro
