I wanted to spread fertilizer (46-0-0) on my food plots that are already established. The food plots are about 3-5 inches high, and I believe its time to put more fertilizer on it. How do I spread the fertilizer without crushing the plants? If I use my atv with the spreader, I will crush the established plants. If I use a hand spreader, when I walk on the food plot I will smash the plants. How do I spread this 46-0-0 fertilizer without damaging the plants?
