The purpose of this study is to compare the use of potassium acetate, at various growth stages in a soybean-after-soybean rotation, and its impact on yield and profitability

2019 Southern Illinois Soybean Potassium Rate and Timing Study - Soybean-After-Soybean

2019 R4 DISEASE RATINGS (1-5, 1 IS LEAST DISEASE)

Planting late into wet conditions, followed by late-season drought, led to smaller root systems. the dry weather also limited potassium uptake, so supplementing it paid in 2019. University data indicates a correlation between applied potassium and lower disease ratings.
