The number one thing that crop rotations do is they break the life cycles of insects, disease, and weeds, which helps us to reduce our pesticide use. Good crop rotation has been around for, as I said, millennia. It's good for the soil. It helps to create the flora in the soil providing more bacterial activity, more worms. It's a benefit for the surrounding environment and cover crops, because we use a lot of cover crops that prevent the runoff.
