Abstract The emissions of two greenhouse gases (GHG), carbon dioxide (CO2) and nitrous oxide (N2O), from six substrates with different carbonaceous content were compared in short and long-term incubation experiments. Three
natural soils and three artificial chars were mixed with carbon (C) poor soil (Cambisol) to simulate real conditions
after application of char to farmland. The natural soils were a Cambisol, an Anthrosol and a Histosol with C contents of 1.3%, 4.4% and 13.2%, respectively. The three chars produced through thermal conversion of wood chips
by hydrothermal carbonisation (HTC), fluidized bed gasification and pyrolysis had C… More >
