- The reduction in greenhouse gas emissions from agriculture is of particular importance at present. In recent times, biochar addition to the soil was suggested as a means of mitigating greenhouse gases emissions from arable fields. More specifically, biochars with useful properties and those produced from easily available waste materials are still being sought. In the presented experiment, the CH4 absorption potential of four biochars incubated at 60 and 100% water holding capacity with the addition of 1% CH4 (v/v) was investigated for 28 days at 25oC. The potato stem and raspberry stem biochars showed much higher potentials for CH4 uptake than wood offcuts biochar and sunflower husk biochar. Potato stem and raspberry stem biochars incubated at 60% water holding capacity were characterized by a methane uptake rate of 8.01 ± 0.47 and 5.78 ± 0.17 mg CH4-C kg-1 d-1, respectively. The methane removal potentials of the other biochars were clearly lower. The advantage of the biochars from raspberry and potato stems over the wood offcuts biochar also results from their significantly lower production of carbon dioxide. Consequently, these materials have a high potential for agricultural use, in view of their impact on the greenhouse gas balance of the soil.
