Tissue results from week 1. I don’t have the soil test results back yet for these samples. This is v3-v4 corn. The first one is from a good spot in the fields the second is from a bad spot based on visual appearance and yield history. Good spot was visually taller and the leaves were bigger. The higher P reading in this spot was the key to that increase growth imo. No infurrow starter was applied to this field. The only liquid was in the 2x2 and I’m not 100% sure what that was yet. I need to double check with the grower on that. My question is on the calcium. In the “bad” area the calcium is quite a bit higher. I’ve seen this be the case before in soybeans where my poorer yielding spots had much higher calcium (above 1) than my better yielding spots. I’ll note that these 2 corn samples were on soils with an exchange around 20 and the soybeans that i mentioned were on sands with an exchange of 5-7. Any thoughts as to why higher calcium is occurring on the “poorer” spots compared to the better and if that’s causing a problem?
