Аннотация:In experiments on leached chernozem, gray forest, and soddy-podzolic soils, correlation and regression relationships between soil production of C-CO2 and parameters that characterize mineralization-immobilization transformations of nitrogen were determined. The changes in the amount of C-CO2 released from the soil after the application of 15N labeled fertilizer did not correlate with the extra nitrogen, calculated by a traditional method; however, they characterize reliably the value of the net soil nitrogen mineralization. The production of C-CO2 by soil reflects rather objectively the full cycle of mineralization and immobilization of nitrogen, but not separate processes involved in this cycle.
