Soil bacterial community composition in rice–fish integrated farming systems with different planting years

Abstract The high productivity and efficient nutrient utilization in rice–fish integrated farming system are well reported. However, the characteristics of soil bacterial communities and their relationship with soil nutrient availability in rice–fish field remain unclear. In this study, we selected...
