NE SD | I just got back data from 4 fields of corn (waist high). Most elements were ok but all had low zinc and potassium. I put liquid zinc in my starter fertilizer in furrow and had strip tilled last fall, putting 60 units of potash down (100# of product). Is there a problem with availability or do I just need more? Seems like I should have enough on according to soil tests and removal rates of the crop. | |
