- Аннотация: Gray forest soils are one of the typical agricultural soils in European part of Russia, but their role as a sink for atmospheric methane is poorly documented. We have investigated variability of CH4 uptake process of agricultural gray forest soils, Moscow region, Russia, at different time scales (monthly, daily, hourly). Additionally some belowground factors impacting soil CH4 consumption were tested for their short- and longterm effect. It was found that the gray forest soil was the sink for atmospheric methane and average annual net rate of methane oxidation for 3 years was calculated as 20 mcg C-CH4 m h . The large fluctuations were 2 1 evaluated in response to the daily cycle and were found to be strongly influenced by air temp erature. Nitrogen and manure fertilization resulted in short-term (3-4 weeks) shift from CH4 uptake to CH4 emission, which was determined by transformation of labile fractions of soil organic matter.
