Long term crop rotation effect on subsequent soybean yield explained by soil and root-associated microbiomes and soil health indicators

Abstract Crop rotation is an important management tactic that farmers use to manage crop production and reduce pests and diseases. Long-term crop rotations may select groups of microbes that form beneficial or pathogenic associations with the following crops, which could explain observed crop yield...
