This paper gives an overview of 50 selected long-term fertilisation experiments all of which are older than 30 years in Germany and Eastern Europe. Examples of evaluation are given. From the combined results from 13 long-term field experiments, the range of optimum mineral

,Elektronische Fermi-Flüssigkeit,the former case, we assume that the measurements we make are the best representation of nature, and that model structure should follow. While this may simplify model testing, it may not yield a particularly useful description of SOM dynamics. There is no question that most of our knowledge about SOM

Such methods provide an immediate qualitative description of the differences, highlighting trends, different types of errors and distribution patterns of simulated and measured values. However, model evaluations or comparisons should idea
