hey, so im starting my own hay business, I have 8 acres of field. it use to be half alfalfa half grass. hasn't been done in years. im curious about ground prep and planting. by ground prep in talking about ploughing/cultivating. what do I do to the field and in what order? and I keep seeing lots of stuff about how to plant alfalfa but it's all for small household gardens. after ground prep how do you plant the alfalfa? what kind of seeder?
