How the CH4 balance and the total GHG balance are changing if agricultural peat lands are transformed into wetland nature

Peat oxidation in agricultural peatlands can be reduced if those peatlands are being restored by raising the water table and by reducing agricultural intensity. These measures alter the carbon cycle and probably turn greenhouse gas sources into sinks. However, large uncertainty exist of such measures on the methane (CH4) balance and on the contribution of CH4 in the total greenhouse gas balance. Therefore, a landscape scale experiment has started in 2005 in which three peat areas are sampled for CO2 and CH4 and in which agricultural intensity ranges from high to low. The poster shows the resul... Mehr ...
