This is a tough question to answer fully, and I understand where you are going. It would be great if we could plant a top end food plot, and make money off it, at least enough to cover the expense. You have a couple options, but most will only provide an attractant, or less than ideal year round nutrition plot.

That being said, Alfalfa or a red clover/grass mix is probably the most easy to sell, as hay or silage to a farmer. Just make sure you have a buyer lined up prior to planting, some farmers will not use red clover, etc. White clovers do not normally grow very tall, and its tough to convince a farmer its worthwile to harvest, it can be done, I've done it - but they would rather do alfalfa or red clover in my area.

Corn is also an option, and Ph only has to be 5.5-6.0 to grow well. Again, you may need to spray, and again have a farmer lined up to pick it (I assume you do not have a picker, maybe not a planter). There is good resale for picked corn in most areas.

Remember that when you plant a crop where someone else will harvest it, they must be assured that rocks are picked, and the ground level for their expensive equipment. The first time a neighbor farmer mows your hay, and takes out a blade with a big rock, you'll be all done.

Oats, Rye or wheat - are poor at selling, since they are so cheap to plant, and require a combine to harvest. Same goes for soybeans in most areas.

As you can tell, I assume you do not have much farm equipment. If you do, say have a baler, and haybine, then you are all set. Just get a buyer lined up.

Good luck
