The objective of WP 4:
- to assess the environmental and economic impacts of using the new manure data, as provided by the methods developed in WP2 and WP3, on farms,
- to develop and harmonise nutrient bookkeeping methods using the new manure data, and
- to assess the impacts of implementing the new manure data in policy instruments.
The ultimate aim of WP4 is to develop a more equal and comparable basis for manure utilisation and its regulation throughout the BSR via tested use of the new manure data.
