Redox measurements were used to study whether different mitigation options affect methane emission and production by altering the electrochemical environment in rice paddy soil. These mitigation options include field drainage, use of different cultivars, and changing soil texture. Results indicate that the redox potential (Eh) is an accurate indicator of whether or not methane is produced. Also, the timing of methane production and emission was found to be dependent upon the reduction of iron and subsequent increase of the ferrous ion concentration. Field drainage is a mitigation option that successfully lowers methane emission rates by increasing the Eh. By studying the other mitigation options, it was found that once sufficiently negative Eh values are reached, different non-redox parameters control the actual amount of methane emitted.
