The pre-mill germination test is conducted on seed that has not yet been fully processed and cleaned. Before planting, we remove the inert matter and foreign seeds, as well as the very small and immature seeds that would normally be removed in the cleaning process. The cleanout percentage is reported along with the germination test results. This is distinctly different from a standard germination test in which all of the pure seed units are planted, including the small immature seeds, even if it is apparent that they may not germinate.
The pre-mill cleanout can be customized to reflect seed size or other factors. Please specify if you have a specific criterion.
