Weed suppression of most all annual winter and summer weeds. Very good for water infiltration and soil building Reduced dust and sunburn. Continuous year round habitat for generalist predators for mite control. Extra nitrogen use up to 30 or 40 units annually. In thick clover sods gophers can become a problem if not controlled.
Permanent clover is very difficult to control with herbicides on the berms.
An annual planting of vetch, peas, bell beans, and often oats for orchards that are disced. When incorporated and irrigated a good stand of green manure will usually release over 100 units of nitrogen to the prunes through the growing season. Nitrogen fixation with legumes. Water infiltration especially when grains are added to the mixture. Abundant generalist predators in the spring.
