Abstract
The objectives of this work were as follows:
• To critically review information in existing literature and data. This would help to develop an improved understanding of the factors contributing to pollution by P and N.
• To identify regional opportunities for spreading slurry
• To estimate the regional opportunities for storing slurry
These objectives were pursued in the following way. The first target was addressed by literature review, by an in-depth review of the Fertiliser Use Survey (Coulter et al., 2002) and by a revised statistical analysis of nutrient loss data from former trials at Johnstown Castle. For objective 2, a mapping exercise, using detailed rainfall data, indicated the climate risk element of slurry spreading. A similar approach was adopted for the third objective where climate and other data were used to plot maps of slurry storage requirement.
