Optimal Utilization of Phosphorus, Potassium and Sulfur Fertilization in Corn-Soybean Rotations


Start Date: 2011

Principal Investigator: Daniel Kaiser

Organization: University of Minnesota, Department of Soil, Water and Climate

Status: Complete

Background Information:

Making sure appropriate nutrients are applied in cropping rotations is key to maximizing both yield and profit potential. Past research has shown yield benefits for phosphorus (P), potassium (K) and sulfur (S) applied to corn and potentially to soybeans.


This study examines the effect of the application of these nutrients on corn and the following soybean crop to determine if higher nutrient levels and specific combinations of nutrients are necessary to obtain optimum yields.
