Dioxide fluxes reelase from soil after application of different doses of biochar

Original language description

Climate change is a global problem and carbon sequestration is one of the possible ways to reduce it. After application of organic matter to the soil, most of the carbon is mineralized and released into the atmosphere where it becomes a part of the greenhouse gas. Biochar is also an organic matter but it contains carbon in a form that is mineralized slowly (hundreds to thousands years). In addition to these complex compounds, it also contains readily available carbon and also aromatic substances which may be toxic to soil biota. The experiment was aimed to compare the effect of different biochar doses on soil respiration activities. In our experiment, soil mineralization was determined using an alkaline sorbent (Soda lime) at different biochar doses (2, 10, 20, and 50 t/ha). The sorbent has the ability to bind carbon dioxide which can be subsequently determined in the laboratory. Measurements were carried out every 7 days for 4 weeks. In all variants, mineralization was increased compared to control. The highest release of carbon dioxide was measured in the variant with dose of biochar 20 t/ha. Mineralization was not directly proportional to the biochar dose as it varied across variants. The reason may be whether positive effect of biochar prevails in soil biota (increased soil moisture, readily available carbonaceous substances, etc.) and exceeds the level of inhibition by toxic substances or not.
