DISTRIBUTION OF PHOSPHORUS FORMS IN CHILEAN SOILS AND SEWAGE SLUDGE BY CHEMICAL FRACTIONATION AND 31P-NMR

The disposal of sewage sludge from domestic wastewater treatment plants is a growing problem worldwide. Because of the total P content and other characteristics, it is highly probable that in Chile important amounts of the sewage sludge will be disposed of on agricultural lands. The distribution of...
