Dude, have you even got your stand built yet?
I usually plant a fall and winter plot consisting of wheat, oats, rye, austrian winter peas, rape seed and clover and never do any plowing. You can probably find a "seed blend" with fertilizer at your local feed store. I paid about $16 for a 50# bag that plants about 1 acre. Clear what you can but, getting to bare dirt is not neccessary but, the closer the better! Just broadcast the seeds before a rain and let her rip! It's a little early and dry right now. I would wait to the end of August or the beginning of September! Oh, and yes, I would add a few salt blocks to tha grocery list and get them out just as fast as I could!
All of the seeds mentioned above are annual except for the clover. You should get between 4 to 6 years out of that. More that likely, it will be red clover but, some feed stores have it mixed. I have been checking into purple prarie clover but, have never planted it yet. It has a higher nutrional value than red and white. The rape seed and austrian winter peas tops the list in the mix for nutrional value with the oats coming in a close 3rd. However, I had a problem with the wheat choking out some of the daylight on the rest of the plants, especially the austrian peas and rape. I may omit the wheat this year, if possible!?!
Good Luck!
