Abstract

The dependence of carbon mineralization and denitrification on soil chemical properties was studied in order to determine the spatial variability of these processes. Multiple regression models that describe 57% of the variation in denitrification and 97% of the variation in the organic carbon mineralization were developed. It was found that the simulation of potential denitrification activity is a more difficult problem than the simulation of C mineralization. Application of the orthogonal regression method proved thatthe fluxes of CO2 and N2O depend on the content of exchangeable cations inthe soil (12-17% of the variability); the effect of soil acidity and the organic matter content is shown to be more significant (74-75% of the variability).
