SC NE | I prefer MESZ to MAP. Each pebble of MESZ has phos, sulfur and zinc in it. When you blend MAP, AMS and zinc, your spread won't necessarily be as uniform as you won't have near as many sulfur and zinc pebbles to spread over the same acres. Every MESZ pebble has a little sulfur and zinc in them so the fertilizer is spread more uniform... in theory.
I've never used 40 rock, but what I've heard it is the lower quality version of MESZ. | |
