In 2019, it was very wet from planting through harvest. Tissue and soil N tests at V5, V10 and R1 revealed we had moved a lot of nitrogen from the upper foot of soil especially from fall and preplant applications. That was also true for sidedress applications in sandy soils without stabilizer. We recommended an additional applica
