Cover crops need to be terminated (killed) before or shortly after the cash crops are planted. If termination is incomplete, the cover crops act as weeds, robbing the cash crops of moisture, sunlight and important nutrients.
Although there are many benefits to selecting a cover crop species mix that is made for specific soil types and needs, in practice, cover crop species selection is driven by more practical considerations, including cost, availability, seeding date, seeding method and termination method.
