Cover Crops
and Green Manures

Cover crops are defined as low-growing understory crops that often grow outside the main-crop growing period. Cover crops offer services to the cropping systems such as adding soil N, reducing soil erosion, increasing soil quality and suppressing weeds. Green manure crops are crops grown specifically to replenish the soil system, typically with N, but also P and other nutrients. In wet areas, green manure crops are often grown as cover crops, while in drier areas green manure crops are typically used during the summerfallow phase of the rotation.
