Abstract
Laboratory experiments were conducted on the effects of rice straw application and inorganic N fertilization on methane (CH4) production from a flooded Louisiana, USA, rice soil. A significant increase of CH4 production was observed following rice straw application. Methane production increased in proportion to the application rate. Urea fertilization also enhanced CH4. The increase in soil pH following urea hydrolysis may have stimulated CH4-generating bacteria by providing more optimal soil pH conditions or contributed to the drop in redox potential (Eh). The significant decrease in both the production rate and the total amount of CH4 by application of NH4NO3 was associated with increases and almost completely inhibited CH4 production. However, this inhibitory effect was short-termed. A direct inhibitory effect of sulfate on methanogenesis might have been more important.
