Wetlands can be defined as transitional ecotone ecosystems between terrestrial and aquatic conditions and are characterized by the waterlogged soils. Prevailing anaerobic conditions in wetland soils slow down or suspend decomposition processes of organic matter. These processes are connected with the production of soil biogenic methane (CH4) and carbon dioxide (CO2). CH4 is a product of organic decomposition under anaerobic conditions, while CO2 is a product of organic matter decomposition under aerobic conditions. Anaerobic conditions stabilized in profiles of wetland soils determine a crucial role of wetlands in the carbon cycle at both the local and the global scale. Wetlands sequestrate well carbon into the soil for a long period, and their soils contain about one-third of the global soil carbon stock. It is a bit of a paradox that ecosystems, which are responsible for creating huge carbon storage, are now under scrutiny in case of CH4 emissions into the atmosphere.
