Introduction
The Replacement Cost Method (RCM) General Idea and Problems at Application
Chemical Processes in the River Modelling Changes in the Nitrogen Retention
Valuation of the Nitrogen-Retention Practical Problems using the RCM
Ingo Bräuer • Institute of Agricultural Economics • University of Göttingen
AimsAims
1. Development of a user-friendly procedure to evaluate the ecosystem function N-retention to promote the use of RCM
2. Discussion of the choice of technical substitutes
