Do you all not rotate? Just the same crop in the field year after year after year? That is so shocking to me; growing up in the Midwest we were always rotating the crops, usually between the standard mix of corn, soybeans and wheat, but occasionally through sorghum or a grass mix. I assumed it was the standard for conventional agriculture everywhere.
