Yup! Funny you should mention it. The (organic)farm owner, who has an unbelievable resume in the medical profession, was just telling me his plans, to go with five years of Alfalfa, followed by two years of Corn, with Austrian winter peas between the corn years, this will keep out the weeds while the peas add nitrogen. The Alfalfa and Corn get sold to a local organic dairy to feed the cows that produce organic milk.
