CAN YOU USE DEF (DIESEL EXHAUST FLUID) AS FOOD PLOT FERTILIZER???? In this video I go over the analysis of DEF and tell you how much is needed to put a LB of nitrogen down. All food plots whether corn, soybeans, alfalfa, clover, turnips, radishes, cereal rye, winter wheat and oats all require fertilizer in order to grow and give whitetails quality nutrition needed to grow larger racks. is using DEF a viable option???
