The purpose of this study is to evaluate various starter fertilizers, applied in-furrow, and their effects on yield and profitability.

2017 Minnesota AgRevival Corn Starter Fertilizer Study

Of the four products tested in this study, OptiStart/Climb is the only product containing sulfur (S). We know S helps in the utilization of nitrogen and helps in protein synthesis. This could explain the yield advantage of 7.6 Bu./A. over the control. OptiStart/Climb also provided a 4 Bu./A. increase over the next in-furrow product. It appears that using a starter containing S at this location helped in 2017.
