In this paper we describe these potential problems, and identify the main sources of error when interpreting SOM data from long-term experiments.

Why evaluate soil organic matter models?n SOM content, composition or dynamics can have far reaching impacts. Some changes occur slowly over periods of decades so long-term experiments are necessary to measure them. Models are the only practical means of making projections at places other than the sites of long-term experiments.
