The purpose of this study is to determine what effect different closing wheels have on plant emergence, yield and profitability in various planting conditions.

2018 Central Illinois Soybean Closing Wheel Study - Soil Conditions

In 2018, the soil conditions at the time of planting this study were not as marginal as we had hoped for, and good seed-to-soil contact and furrow closure were obtained with both treatments. Small differences were observed in both plant populations and yields across all treatments. Plant stands were slightly higher when using two Yetter Poly Twister closing wheels, which may have helped maintain the soil structure near the soil surface.
