THE INFLUENCE OF FERTILIZATION SYSTEMS ON CO2 EMISSIONS FROM CHERNOZEM TYPICAL

Abstract

The article is devoted to influence of fertilization systems on emission of carbon dioxide from chernozem typical. Systems of fertilizers are a significant factor that affects CO₂ emission from the soil. Organic fertilizers have a special importance for the maintenance of soil quality in connection with that they are a necessary component of the forming and maintaining its status of humus, as well as control of microbiological processes. The aim of investigation was to determine the characteristics of the intensity of CO₂ emissions in the application of different fertilizer systems considering the seasonal dynamics, and estimates the annual loss of emission soil carbon. The observations showed that fluctuations in the emission activity during the vegetation period were more significant, and it is associated with changes in temperature and soil moisture. Overall, the investigations are showing the difference between the intensity of CO₂ emissions under different systems of soil fertilizer, with the predominant influence of organo-mineral system.
