Modelling C Turnover through the Microbial Biomass in Soil

Abstract

A simulation model was developed to describe the transformations of C and N in the soil. The aim of this study was to validate the concept of fractionating organic residues into pools of different decomposability in order to describe the residue quality. All the data obtained were compiled in the mathematical model and the simulated data were compared with measured data of C- and N-mineralization and soil microbial biomass. According to the different standard deviation values, the simulation was termed "perfect", "adequate" or "poor" and in our experiment, all the curves of C-mineralization were "perfectly" fitted with the model used.
