On the land I hunt, we're in the process of making several small food plots--by small I mean 1/2 to 1 acre in size. We've got a brush mower for behind the 4 wheeler that knocks down pretty much everything, and then we put on some weed killer, let that sit, rake it off and then run the disc over it. We usually wait to plant until the forecast is looking like some good rains, because we too live about 1 hour away...so we can't be watering it all to easily.

Anyways, we've planted some turnips, clover, alphalpha, etc. and they seemed to do pretty well this last year. One thing we are going to try this year that you may want to look into is using Plotsaver. I read an article where someone tested that with great results, so why not try it!

Anyways, good luck with your food plot, but in my opinion, I would suggest making it either larger, or putting more of them around your land
