Norseman,

Forget the disk and plows, and buy a nice 25 gallons sprayer and Roundup. Kill it all first, then use a light, cheap drag, just to break up any clumps of dead grass, debri, and then get a 30 gallon lawn roller to cultipack, or just broadcast before a good rain.

You can get Ed Spinnazzolas book, Food Plots 1-2-3, from the QDMA association, and there is a good bit of info in it concerning no-till plantings.
