The Environmental Impact of Phosphorus from the Agricultural Disposal of Sewage Sludge -Stage 2

<< previous page 
Price: £150  

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.
