6.1 Model calibration procedures

The model calibration/validation procedure is the most important stage in the modeling process. For systems handling nitrogen and carbon, it can be illustrated as shown in figure 10 .

This procedure is iterative, and it should not be forgotten that it is an integral part of the entire modeling project process. Model calibration may, for example, highlight missing (or misidentified) data, requiring a return to the data collection stage (see figure 8...
