Approaches to determine the nutrient retention ...

There are some good ideas and approaches around the world to naturally control the nutrient pollution of water bodies. In financing the projects or in marketing the nutrient retention, it is important to be aware of the difficulties by quantification of retention rates and the fact that many different interest groups are involved. In order to minimize the problem of measurability and the many interest groups, it is recommended to start pilot projects for sub-basins. In this context, potentials for nutrient retention including success control and monetary effort should be tested and analysed.
