Low environmental load technology for liquid livestock waste based on control of novel reactions mediated by microorganisms

This study explored feasibility of harnessing denitrifying methane-oxidizing bacteria in a forage rice field as a site where aerated liquid livestock waste is supplied as a fertilizer. A PCR primer to detect and quantify these bacteria was designed, elucidating their abundances and locations in various rice paddy soils. A new strategy based on water control and the degree of liquid livestock waste dose allowed noticeable reductions of greenhouse gases, i.e. methane and nitrous oxide, from a forage rice paddy field. Furthermore, a plausible mechanism of abrupt nitrous oxide production from a rice paddy field after water drainage was elucidated.
