CO2-evolution and carbon sequestration in field experiments with different soil tillage practices
Original language description
Changes in frequency and intensity of soil tillage modify soil properties in the soil profile. Field trials with three tillage practices - conventional tillage (CT), reduced tillage (RT) and no-tillage (NT) practices are carried out in Prague ? Ruzyne since 1995. Lower organic carbon contents (Corg) was found under CT in comparison with the Corg found in RT and NT. The CO2 ?fluxes from soils are related to the intensity of their cultivation as consequence of the higher mineralization of the soil organicmatter. The ploughing increased the CO2-fluxes from soils in the field experiment. The results show lower CO2-C fluxes from soils in RT and NT in comparison with CT. The summer ploughing before sowing of oil seed rape can intensify the mineralization processes in soils and in consequence increase the evolution of CO2-C from conventionally worked soils. In addition, soil temperature and humidity affect the CO2-C fluxes from soils under CT, RT and NT practices differently.
