Development and Test of Potassium Management Algorithms for Corn


Start Date: 2013

Principal Investigator: Ron Potok

Organization: Solum, The Mosaic Company, IPNI

Status: Complete

Background Information:

This project explored algorithms for potassium (K) management in corn, using a variety of measurement-based parameters. Since potassium availability and transport to the plant are impacted by so many variables, this study focused on measuring as many known factors as possible.


The goal of this research was a better understanding of the interaction between yield and soil K on Minnesota farms, ultimately leading to the development of algorithms for potassium management.

 Key Findings:

This potassium project was only funded for one year and was terminated when Solum company was sold. The goals of this research are still a concern in developing better potassium recommendations. These objectives are being researched in other AFREC funded projects.
