Check your local seed/feed mill if you have one in your area. They will have seed at a fraction of the price. My local mill had a pre-mix of several different clovers, chicory, rapeseed, rye grain and turnip. Even through this major summer drought we are having, my plots are miraculously makig it.
Here's a picture of one of the old logging roads on my property where I planted the mixture. The turnips are getting huge.
