In 2019 Northern Ireland was successful in applying to the European Commission to renewal a Derogation from the Nitrates Directive permitting the land application of up to 250kg N per hectare per year from grazing livestock manure under certain conditions. This Derogation, for the period 2019 to 2022, is also implemented through the NAP Regulations.
