The purpose of this study is to compare the use of potassium and sulfur products, applied through the wings of Precision Planting’s FurrowJet®, to determine their impact on yield and profitability.

2018 Indiana Soybean Potassium and Sulfur Study - Soybean after Soybean

Sulfur (S) has received some attention in recent years due to the Clean Air Act, which essentially removed “free S” from the atmosphere as result of emission reductions. Sulfur has many roles within the soybean plant including aiding in rapid root growth, developing chlorophyll, and facilitating nodulation and nitrogen fixation. Interestingly, this year we did observe extra lateral root growth towards the bands of applied Feast® Side-Kick®, however, this did not result in substantial yield gains over the potassium product Korrect™. Weather conditions this year were extremely favorable for the mineralization process, which likely supplied sufficient amounts of the sulfur needed throughout the growing season.
