How to Sample Cover Crop Biomass

What are you getting out of your cover crop? Knowing how much of each cover crop species is growing in your field is the first step in answering that question.

In this step-by-step video, University of Delaware Extension Weed Scientist Mark VanGessel explains how to collect, dry and measure a sample of cover crop biomass from a field. These measurements can help growers estimate how much weed suppression or nutrients they can expect from a cover crop.
