2021 Orthman Research Yield Book


Soybean Fertility Trial The purpose of this trial was to demonstrate the value of fertility when raising soybeans. More farmers are utilizing fertilizer for soybeans but still some do not understand the value of fertilizing soybeans. On April 13, 2021, the ground going to soybeans was strip tilled with 49 gallons per acre of a blended liquid fertilizer. That blend provided 61.3 pounds N, 126.75 pounds P2O5, 43.51 pounds S, and 4.51 pounds Zn. This program was designed to be aggressive to help us with some very low P and Zn soil test values. In one area of the farm we did not apply the liquid in the strip-till operation.
