The term 'cover crops' implies that these plants are used primarily as soil covers. However, as legumes, they perform many beneficial functions for the soil, the oil palm and rubber trees as well as the environment.
Benefits of Growing Cover Crops:

Serve as a living carpet of perennial crops
Control weed dominance
Lessen disease and insect carry over
