This project involved 12 field experiments receiving biosolids from 1994. It was undertaken by a collaboration of WRc, ADAS, Integrated Approach to Crop Research (IACR-Rothamsted), Scottish Agricultural College (SAC-Auchincruive)
and Macaulay Land Use Research Institute (MLURI). In Phase II an intensive soil and crop sampling exercise is in progress to assess the long-term effects on soil fertility, including statistical analysis of the data and modelling of soil component
effects on soil microbial properties.
This project received funding from the Environment Agency, The Department of Transport and the Regions (DETR), The Ministry of Agriculture, Fisheries and Food (MAFF), the Scottish Executive Rural Affairs Department (SERAD), The UK Water Industry Research (UKWIR) and The National Assembly for Wales.
