The study analyzes biochar application in soils for carbon sequestration, evaluating GHG fluxes such as CO2, CH4, and N2O, and the economic viability. The field experiment in Traismauer, Lower Austria, compares biochar-treated and non-treated soils to assess differences in soil GHG fluxes. This Diplomthesis aims to provide insights into the potential of biochar as a sustainable mitigation strategy for greenhouse gas emissions.

Project “Biochar for carbon sequestration in soils: Analysis of production, biological effects in the soil and economics” (Klima und Energiefonds des Bundes) The application of biochar to soils is a promising technology to mitigate the greenhouse gas (GHG) carbon dioxide (CO2) by increasing long-term soil carbon sequestration. To evaluate this practice as a sustainable, future mitigation strategy, the soil-atmosphere flux of CO2 but also of potent non-CO2 greenhouse gases such as methane (CH4) and nitrous oxide (N20) have to be considered. The Diplomthesis aims at evaluating GHG fluxes from biochar treated and non-treated soils in a field experiment. Our hypothesis is that biochar-treated and non-treated soils will show significant differences in soil GHG fluxes. DIPLOMA THESIS Field site:The field site is situated in Traismauer (Lower Austria). Biochar (softwood : hardwood = 4:1) was applied on 16.03.2011.
