The Signficance of Sewage Sludge as a Source of Phosphorus Loss from Agricultural Land to Surface Waters : A Literature Review
Sludge applications based on nitrogen requirements may lead to an accumulation of phosphorus in soil. There is a risk of consequential eutrophication in vulnerable areas. Although the immediate availability of phosphorus from sewage sludge may be low it is considered a useful source to crops in rotations. P loss in surface and sub- surface run- off from freshly sludged land is comparable or less than that from other fertilizers, typically less than 1% of phosphorus applied. The continued land application of sludge poses only a small threat to the environment.
