Abstract

The CO2 and CH4 as the most important carbon based GREENHOUSE GASses have negative effects on the environment. They have close relationship with soil carbon cycle. For reducing the atmospheric concentration of these gasses, it is possible to fix them into the soil in the form of organic carbon. CO2 is the most abundant GREENHOUSE GAS in the atmosphere and its concentration has increased up to 30% after industrial revolution (Houghton et al 1996). Releasing the CO2 from the biosphere includes soil emissions and cutting and burning the forests. Methane is one of the GREENHOUSE GASses with 21 time's green house effect greater than CO2. 20% of global warming in recent years is due to the increase of the atmospheric methane. Reduction is most important process in the soil producing methane that caused by microbial decomposition of organic matter in anaerobic conditions (Bowman, 1990). The increase of CH4 is because of the increase in the rice planting, which is the source of more than 50% of atmospheric CH4 (Ehhalt and Smith, 1978). Methanogenes (bacteria that produce CH4) are anaerobic; therefore, soil moisture condition and irrigation method (rice paddy fields in contrast with alternative irrigated field of wheat) have straight effects on producing methane and emissions from soil. Wheat and rice are two major cereals in Iran that the major difference between them is the time of planting and water efficiency. High irrigating (in rice agriculture) is an effective agent to change carbon condition in soil (Rees et al. 2005).
