Abstract

Even though organic wastes have been used as sources of nutrient elements for many centuries, a rational basis for their use has never been developed. Recommended rates have been based on experience and research planned without the ability to match application rates to the needs of crop plants, and with little information on the rate of biological decay of the organic materials.
