Development of catchment sensitive farming will require calculations of the overall nitrogen and phosphorous load for farmland and river catchments. We therefore recommend that DEFRA commission a periodic (five yearly) appraisal of catchment-wide nutrient flows across each of the major river catchments in England.

We therefore recommend that DEFRA commission a periodic (five yearly) appraisal of catchment-wide nutrient flows across each of the major river catchments in England. Such appraisals should then be used by local authorities and planning authorities to inform decisions on new housing developments and intensive livestock units, taking into account the cumulative impact of such developments on river catchments.
