Interactions among anaerobic and aerobic N mineralization, nitrification and selected soil properties

Nitrogen mineralization and nitrification are important soil quality parame ters. The aim of our research was to determine the dependence of the microb ial parameters which characterize N mineralization and nitrification on sel ected physical and chemical soil properties. The results from soil monitori ng representing the major soil types of the Czech Republic show, that N min eralization measured under aerobic and anaerobic conditions was checked by the concentration of organic matter (N-tot, C-org). Aerobic N mineralizatio n decreased with increasing cation exchange capacity. The values of cation exchange capacity and pH influenced the level of nitrification in our resea rch.
