Some really great ideas here!
I plant common wheat and oats and try to get in a least 4 acres. Add a couple hundred pounds of fert. pre acre before planting. Pretty inexpensive to weight out the benefits. The oats serves as good browse up to a hard freeze. Not uncommon to count 14 to 21 deer in the oats some evenings. The wheat serves right into December until browsed down. Wheat also grows early in Spring for good food source. I recover cost buy combining the wheat, baling the straw and selling. Funny, I just realized I have a great thing going on here, LOL.
