UW–Madison Division of Extension Provides Corn Grain Moisture Conversion Chart for 2026

By Kevin Jarek

Approximately three million of the four million acres of corn grown in Wisconsin each year are harvested as grain. This can be either dry grain intended to be stored at 15% moisture or high-moisture shell corn (HMSC), which is used in many dairy and livestock rations across the state.

Extension developed an Equivalent Price per Ton for HMSC conversion chart for those farmers and ag professionals who wish to negotiate the value of corn above 15%. The Excel file uses current agricultural price for LP (liquid propane) gas and electricity ($KWH) as well as a standard shrink factor to determine a fair value for HMSC converted to a dry corn equivalent.
