Could you elaborate on how low is too low? Many micro-nutrients I see in our soil samples show 0.2 to 0.6 ppm on CU or B and 4-9ppm on Mn and Fe. Despite being low this seems to be plenty per the removal rates of any crop we throw on our farm. Is there a balance that's needed, like the Z-P relationship?
Mn is testing at 5ppm MW labs on cec 40, 92% Ca soil. Tissue test however in corn is showing sufficient for the 10 samples pulled, once each week. Should I fix Mn in this case, or work on something else. For example K is below 2% and Mg is 5% on this field. Both are defficient in tissue samples. Thanks
