The Environmental Impact of Phosphorus from the Agricultural Disposal of Sewage Sludge -Stage 2
Price: £150
Ref: 96/SL/02/3
ISBN: 1 84057 117 9
Progress is reported for the second year of the three year project. Laboratory analysis indicated that phosphorus available may be low for dewatered, composted or dried sludges. Field experiments indicated that phosphorus leachate and run- off from sludged plots was less than that from plots receiving inorganic fertiliser or livestock slurry. Further lysimeter work confirmed that phosphorus losses are negligible from land treated with sewage sludge. Most of the sludge phosphorus applied to land is retained in the topsoil and this may lead to surface run- off.

The Signficance of Sewage Sludge as a Source of Phosphorus Loss from Agricultural Land to Surface Waters : A Literature Review
95/SL/02/1 - ISBN: 1 84057 071 7Sludge 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... More...
