Length of Incubation Time Affects the Parameter Values of the Double Exponential Model of Nitrogen Mineralization
- M. L. Cabrera and
- D. E. Kissel
The double exponential model has been used to describe nitrogen N mineralization in disturbed soil samples, allowing the separation of two N pools that mineralize according to first-order kinetics. We fitted the model to data from various incubation times to study the effect of incubation time on the parameter values of the model. In general, as the incubation time increased, the apparent size of the two N pools increased, whereas their rate constants of mineralization decreased. These results call for caution when comparing parameter values obtained with different incubation times.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
