NE Iowa | Your Mg is not that high in my opinion. My base sats are in the 31-35% range so I'd gladly trade you. Your #1 priority needs to be getting the P levels up. You also need to be apply S, Manganese, and boron. Manganese sulfate will be your cheapest source of manganese and will blend with your P. Also add 1-2# of actual B to your P application. There are 10% and 14% dry boron products that are relatively inexpensive. | |
