Cover Crop Termination

Spraying - Timing of herbicide application is critical for contact and systemic chemicals . Only spray when plants are actively growing ( usually late morning through early afternoon ) and temperatures are warm . Always consult the label and discuss your chemical applications with your local co-op or chemical expert .
Tillage / Mowing - Allow cover crops to develop as much as possible to grow the most biomass , build soil and fix Nitrogen . Generally the closer to reproductive maturity the better depending on the situation .
Grazing - With very few exceptions , almost all cover crops and cover crop mixes can be grazed and provide excellent forage . Proper management is critical to ensure correct time of grazing , utilization rate and grazing height .
