Residual plant nutrient study

Larry Liepold

I practice strip-till in corn and soybeans. Also practice no-till in soybeans where fertility is not a limiting factor. It is my objective to eliminate the fall strip-till operation for the following years soybean crop by applying the phosphorous & potassium at side dress of the com crop. My objective is to intensively sample soil, tissue and water to determine what the corn crop “stole” from the soybean crop.
