It seems that opinions of the Biologic products are mixed, at best. Scientific reasoning is probably going to be hard to come by and the ones touting Biologic are usually the ones selling it. We tried a couple of plots of Biologic a couple of years ago and the results were very poor, in fact we finally disc it in. Many on this forum have posted similar results while a few have had success. I don't know if you can plant any kind of food plots that will be prefered over good agriculture crops.
