The Response of CO2 Flux to Soil Warming, Manure Application and Soil Salinity
Abstract
In this research effect of different soil types (normal and saline), farmyard manure norms (2 ton/ha - 4 ton/ha), manure application techniques (surface and subsurface) and soil temperature levels (20-25°C, 25-30°C, 30-35°C, 35-40°C, 40-45°C and 45-50°C) were examined of the soil CO2 flux on the pots at the laboratory conditions. According to obtained results, soil type (ST), manure norm (MN), manure application technique (MAT) and soil temperature (T) values changed CO2 flux. CO2 flux value of saline soil condition smaller than the normal soil condition. As an expected result, increased the manure amount increased the CO2 flux from soil to atmosphere. However, CO2 flux on the condition that subsurface manure application was less than surface manure application. CO2 flux values at the high soil temperatures were more than low soil temperature conditions. According to the interaction (T*ST, T*MN and T*MAT) results were not statistically significant. Soil CO2 flux were affected by gradually increasing of temperature.
