Fast recovery of atmospheric methane consumption in a Swedish forest soil after single-shot N-fertilization

Methane consumption was measured in samples from a Swedish forest soil once every autumn for 2 years after fertilization with 150 kg N ha(-1) as calcium ammonium-nitrate. Although fertilization initially depressed methane consumption, this effect tended to decline during the remainder of the first year, accompanied by the disappearance of inorganic N. After 2 years, the methane oxidation capacity was found to be substantially higher in the fertilized plots compared with the controls. The difference between years was pronounced, with very high rates registered 2 years after the start of the experiment. These high rates were probably due to a rapid growth of methanotrophic organisms in response to an unusually warm period preceding the date of sampling. (C) 2000 Elsevier Science B.V.
