1.The competent authority shall ensure that maps showing the percentage of grassland farms, percentage of livestock and percentage of agricultural land covered by individual derogation in each county, as well as maps on local land use are drawn up and updated every year.
2.Monitoring shall be carried out on soil, surface water and groundwater in order to provide data on nitrogen and phosphorus concentrations in soil water, on mineral nitrogen in the soil profile and nitrate concentrations in groundwater and surface water, both under derogation and non-derogation conditions. Monitoring shall be carried out at farm field scale and in agricultural monitoring catchments. The monitoring sites shall include the main soil types, levels of intensity, fertilisation practices and crops.
3.A reinforced water monitoring shall be conducted in agricultural catchments located in proximity to most vulnerable water bodies.
4.Surveys on local land use, crop rotations and agricultural practices shall be carried out on farms benefiting from individual derogations. Collected information and data from nutrient analysis as referred to in Article 5(6) and monitoring as referred to in paragraph 2 of this Article shall be used for model-based calculations of the magnitude of nitrate and phosphorus losses from farms benefiting from a derogation.
