of arable or grassland, a number of livestock, and associated inorganic fertiliser
and managed organic manure inputs (Table 3). Pollutant losses from each model
farm were calculated for combinations of soil texture (clay loam or sandy loam) and
climate conditions (net soil drainage 170–620 mm) to represent the range of baseline
pollutant losses across England and Wales.
Table 2:
An example of mapping of mitigation methods (not an exhaustive
list presented here) against potential policy options for invoking

potential to implement this mitigation method. The extent to which
the method is implemented was not considered
