I like tam 90, I have used gulf coast a lot because I could buy it at the end of the season from home depot for around $10.00 a bag. You might check one close to you. Be sure and drag your field after applying to get good ground contact. Anything will work , a piece of old chain link with a tire tied on it to a drag harrow. I add oats to mine in one pasture and cereal Rye in another pasture. A little fertilizer goes a long way to helping a thick stand. From now to Oct 15 is when I plant. Good luck.
