Organic carbon is transformed into CO2 by various interventions applied to the soil and diffuse to the atmosphere. The manures
which used unconscious under available soil moisture and temperature condition makes the soil microorganism activity increased.
This causes CO2 emission increase as well by oxidation of organic matter. In this study, it was aimed to evaluate different amounts
of sheep (20, 40 and 60 t ha-1) and poultry (15, 30 and 45 t ha-1
) manure under different wetting-drying cycles (irrigation intervals
of 3, 6 and 9-days) in terms of CO2 emission and to understand the relationship of soil temperature and soil moisture with CO2
emission. The study was conducted according to arranged in a complete randomized block design with three replications as a pot
study in greenhouse conditions. The frequent irrigation and using high amount of manure increased CO2 emissions. Although the
same amount of organic matter was provided to the soil in different amounts of sheep and poultry manures, CO2 emission was
higher in sheep manure. Soil temperature increased by irrigation at infrequent intervals and high amount of manure. Moisture
retention in the soil increased by using high amount of manure. The linear relationship of soil temperature (R2=0.922) and soil
moisture (R2=0.895) with CO2 emission was found to be quite significant (P<0.01). As a result of the study, using low amount of
poultry manure (15 or 30 t ha-1) instead of sheep manure and irrigation at infrequent intervals (9-days) can be suggested as
precautions to decrease CO2 emissions.
