Response of soil microbial community diversity and structure to soybean-based intercropping and its effects on yield.

ABSTRACT:

Introduction

Soybean-based intercropping has emerged as a key sustainable agricultural practice, which enhances system productivity and improves soil health. Although numerous studies have investigated soybean yield under intercropping systems, the responses of soil microbial community traits and their associations with yield remain unclear.

Methods

Based on 323 observations extracted from 89 peer-reviewed articles, we conducted a meta-analysis to investigate the responses of soil microbial community traits and crop yield to soybean-based intercropping.

Results

Compared to monoculture, our analysis revealed that soybean-based intercropping did not significantly affect soybean yield (effect size = -0.020, 95% CI: -0.105 to 0.065), but significantly changed soil microbi
