Euroharp - Quantification of Nitrogen and Phosphorus Losses from Diffuse Anthropogenic Sources, and Natural Background Losses

The two objectives were:

To describe procedures for the quantification and harmonised reporting of total phosphorus (P) and total nitrogen (N) losses from anthropogenic diffuse sources into primary surface water recipients
 

To describe procedures for the quantification and harmonised reporting of natural background losses of total phosphorus (P) and total nitrogen (N) into primary surface water recipients.
