NE Iowa | I'd try a little shot of beet lime to get your Calcium up from 60% to 63% but it will be tough to get it much higher than that with all the Mg. Your K% is over 3% so just apply removal rates of potash to keep it where it is at. Applying gypsum or large amounts of S to try and flush the Mg could also flush K with it. Live with the Mg and don't skimp on N. It seems like the higher the Mg the more N you need for corn but in your case OM at 4.5% with help mineralize more N from the soil. | |
