This resource was developed to estimate the Equilibrium Moisture Content for a given crop and ambient conditions.
-
Given enough time, grain moisture will come to equilibrium with ambient conditions (temperature and relative
humidity). This is referred to as equilibrium moisture content (EMC) and can be used as an indicator of how
grain moisture will change in the field during late season harvest or when drying in a bin using natural air.
-
If EMC, based on ambient conditions, is lower than the grain moisture, drying will occur. If EMC is higher
than the current moisture, rewetting occurs (although much slower than drying).
Several models to predict EMC have been experimentally developed. In the calculators below, you can select a
specific model, or a composite that averages multiple models. Models may perform poorly for extreme values of
temperature or relative humidity. These calculators are a work in progress, please report any issues with
functionality or results to the authors.
