Summary Not Available – First paragraph follows:
Organic manures or cover crops in southern California citrus orchards have—to a large extent—been abandoned. Scarcity, increased costs, rapid disappearance of organic matter in many soils, and a lack of strong evidence as to its actual benefit to the tree, are among the factors that have limited their use.
