Responses of soil bacterial communities and maize yields to sulfur application across four soil types.

ABSTRACT:

Introduction

This study assessed the effects of S application on maize yields and soil bacterial communities across four sites with different soil types and three S application rates (0 kg ha^-1, 30 kg ha^-1, and 90 kg ha^-1).

Methods

Changes in soil properties, bacterial community diversity, structure, and their contributions to maize production were evaluated post-S application treatments.

Results

(1) S application decreased soil pH, increased available sulfur (AS), and boosted maize yields in all soil types. (2) Reduced Chao1 and Shannon diversity indices were observed in black soil after S application. (3) Bacterial community structure was significantly affected by S application, except in sandy soil, impacting key stone taxa abundanc
