Hello xcell2, I have been making wildlife food plots for a long time now.
I am not a pro gardener, just a farmer. But making a deer plot is EZ. Disc or till the area that you have. You can get the soil tested if you like,but i never do, and i always have great results, after i disc or till i use some 10/10/10 fertilizer, then i plant my seeds,i use millet and soy beans and clover remember to put the clover out last and dont drag it in,it needs to be on the top ,all it needs is contact with the soil.
The other seeds need to be about 1/2" under the soil ,but it doesnt have to be perfect.
The turkeys love the millet and the deer eat when it when its small,but when beans come on they hit it all the time.Now in late fall you need to lime this area real good for the next planting season , because the lime will take about 5 to 6 mths to work.
So just disc or till ,fertilize,plant your seed,grow ,and lime in the fall. This works very good for me ,i use this mix for my hay feilds and i cant keep deer out of them ,thank the lord i love to hunt!!
if you more help just email me
take your kids hunting and you wont have to hunt your kids.
