RE: what kind of food plot??
Many questions would have to be answered first. Are you speaking of a plot that will be planted soon as used as a Fall hunting plot? Do you have the areas already cleared? Have you taken a soil sample to see what amount of lime and fertilizer you'll need to assure that the soil will not bind it's nutrients? All this is critical in developing a successful plot.
Also, this would probably gather more feedback if placed in the Whitetail Management forums below.
