Crop rotation is a common farming practice where different series of crops are planted in the same area each sequential season. Planting different crops on the same piece of land has been used since Roman times and has been proven to improve plant nutrition, benefit soil health, and control the spread of disease. A new study to be published in Nature’s ‘The ISME Journal’ reveals just how profound crop rotation’s effect is on enriching soil with bacteria, fungi and protozoa.
