This study assessed the effects of S application on maize yields and soil bacterial communities across four sites with different types three rates (0 kg ha-1, 30 90 ha-1). Changes in properties, community diversity, structure, their contributions to production were evaluated post-S treatments. (1) decreased pH, increased available sulfur (AS), boosted all types. (2) Reduced Chao1 Shannon diversity indices observed black after application. (3) Bacterial structure was significantly affected by application, except sandy soil, impacting key stone taxa abundance. (4) Black showed higher sensitivity due less stable structure. (5) Soil physicochemical indicators altered such as AS mediated influencing yield. Organic matter (OM) had most significant direct positive effect yield, followed diversity. emphasizes impact properties diverse Understanding these mechanisms can guide precision practices for yield regulation.
