Cover crops are one of the most important practices that farmers can use to improve their soils and the sustainability of their production system. Knowing how much biomass there is in a field is a critical piece of information for cover crop management. Part 1 of this circular provides a step-by-step guide to taking a sample that will be representative of your field. Part 2 provides additional steps for preparing a fresh cover crop sample to send to the Agricultural and Environmental Services Laboratory so it can be analyzed to determine nitrogen availability to the following crop. Equation examples and data sheets are also provided in order to help users calculate necessary information for submission using the given formulas.
