DSK,

I would go with a clover mix or alfalfa in you situation. The long and narrow planting next to cover works great with these and you should get a few really good years out of them. I would add lime if needed and till or plow as soon as you can to break up the soil and leave it. You should be able to plant between the end of March to the end of April. You will need then need to add what ever fertilizer you need then till or disc it in then plant your seed. You may not need too much lime or fertilizer if the farmer is already adding some to his field your soil sample will tell you that.
