I am looking to do maybe three acres of winter wheat and clover for the wildlife on our property. My question is, what do I need to start with in breaking up the soil? A bottom plow, and disc harrow, a roto tiller, or something else? The ground has been plowed before, but as it sits now it is covered in pretty thick native grasses. It is Missouri River bottom soil, not much clay at all. But the one field has a bunch of chunks of flint from the Indians. Some pretty darn big. I plan on trying to pick up most of the big pieces before I start breaking ground. Also, what other implements do you recommend for small food plots?. Thanks in advance.
