Abstract

The aim - to assess water protection zones for installation and management measures the relative efficiency. The use of the different management measures for the protection of bands, the relative cost effectiveness of the detention of nitrogen ranges from 46 to 203 Lt/ kg, retaining phosphorus - from 305 to 902 Lt/kg (maximum - with the existing forest plantations). Phosphorus delay, the installation of grass buffer strips as well as more efficient (that is, 1 kg of phosphorus deter grass strip installation and handling cost less than shrubs or trees, seating and maintenance). Equipping and managing of water protective zones and zones provide not only environmental but also economic benefits. It is appropriate to choose in particular the following bodies of water protection zones in the installation and management tools so that they perform their intended functions - to reduce water pollution biogenic materials to the permitted levels, but in economic terms - to break the link as cheaply as possible
