PHOSPHORUS IN ORGANIC WASTE-SOIL SYSTEMS

Increases in the generation of organic wastes, in addition to decreases in natural resources, make it necessary to recycle these waste materials. In soils, the application of wastes as organic fertilizers, allows to reincorporate nutrients to the biogeochemical cycles. The application of wastes in a...
