The aim of this study was to examine the effect of four different organic substance additions to the soil (hazelnut husk compost and farmyard, pigeon, poultry and sheep manures) on CO2 emission from the soil and the relations of CO2 emission with soil moisture, H2O emission and soil temperature during the wetting-drying cycle of the soil. The results showed that the highest CO2 emissions was in pigeon manure treatment (0.805 g m-2 h-1), and followed by hazelnut husk compost (0.658 g m-2 h-1) and poultry (0.541 g m-2 h-1), farmyard (0.476 g m-2 h-1) and sheep manure (0.424 g m-2 h-1) treatments and soil as control treatment (0.300 g m-2 h-1), respectively. Soil moisture increased, and H2O emission and soil temperature decreased in all organic substance treatments compared to the control (soil), thus the CO2 emission had positive linear relationship with soil moisture and negative linear relationships with H2O emission and soil temperature. Therefore, it could be concluded that it can be more protective opinion for global warming risk applying organic substances (sheep, farmyard and poultry manures respectively) with both low organic matter and nitrogen content to the soil by managing soil moisture to decrease CO2 emission.
