RE: Help with food plots
I would not call myself an expert, but here is a few things to consider. If the plot is in grass now, discing will not kill it. In fact, I had not had good luck with plowing a grass field and putting a legume in it without grass coming back. Spray with roundup after grass greens up a bit should help alot. I would give the roundup at least a day to work before you disc it as well. Someone else here may know more about that. If the field has been in some type of grain, with little or no grass, roundup may not be needed unless you have some sort of weed problem like hen' sbit.
Soil testing is important. Lime and fertilize according to recommendation.
Clover is a very dense small seed that will go into ground quite easily. I have had good luck by working the soil, and then planting before a rain. If you want to work it in, be careful not to get it in too deep. Use an inoculant with the clover.
good luck
