Description:
Wood ash has been used to alleviate nutrient deficiencies of peat forests and to combat acidification of forest soils. Ash may change the activities of soil microbes, including those producing or consuming greenhouse gases, such as methane (CH"4), nitrous oxide (N"2O) and carbon dioxide (CO"2). We studied the effects of wood ash (loose wood ash originating from pulp mill or power plants) on the fluxes of CH"4, N"2O and CO"2 in forests with mineral or peat soils in northern Finland. The ash doses were from 3 to 8tha^-^1. Gas fluxes were measured with a closed chamber method from five recently fertilized experiments for 1 year after application of ash and from five long-term trials 14-50 years after application. Wood ash did not affect N"2O gas fluxes. In the long-term experiments, wood ash increased the soil CO"2 production and the CH"4 uptake and lowered the CH"4 emissions.
