Fig. 2. Temperature and moisture responses of the mineralization rate constants of the active (k_a) and slow (k_s) organic N pools. k_a and k_s were estimated by the double exponential model with fixed pool sizes that were obtained with the data at 35°C and 55% WHC using standard k_a (0.693) and k_s (o.054). The equations for insignificant moisture responses were not shown.
