Crop rotation to diversify the soil microbiome in the semi-arid area of Inner Mongolia, China

The introduction of leguminous crops for crop rotation can mitigate the negative effects continuous cropping on soil health. In this experiment, we designed ten patterns to optimise effect with different combinations types, planting years, and order in a mainly potato-growing region. A 5-year cycle three crops, undertaken Inner Mongolia since 2009, was used test properties microbial structure. relative abundance plant growth-promoting bacteria (PGPB) 32.1% oats alfalfa 22.4% mono-cropping alfalfa, which higher than that potatoes other rotations. Soil moisture main factor influencing bacterial fungal communities. type introduced into greater number years certain planted rotation, order. findings suggest mixed → is suitable maintain biodiversity better physico-chemical sustainable agriculture.
