I agree with Phil, but my plots have never been worked with a disc. Always been no till. I had issues with lack of rain and found info on this site and QDMA on the best no till process. 1) Spray clean year 1. Plant ALOT of Rye. Once it goes to seed and browns, knock it down with a drag, spray it all to get any weeds or late germinating rye. this creates my thatch and produces free Rye seed. Seed whatever you want into it. Since using this method rain amounts mean a lot less than they used to! I planted brassica, Rye, Clover this year doing this with average rainfall that usually isn't enough without the thatch and had the best plot i've had to date. I have a few weeds here and there, but the deer eat them too....
