Biochar or biochar is a black, crystalline, porous, carbon-rich, odourless material used in home gardening and agriculture. It is produced by pyrolysis of biomass (e.g. wood, agricultural waste or other plant material) using a low-oxygen heat treatment process. This process converts the plant material into carbon, which is sequestered in a stable form and thus retained in a long-lasting state. Spread on the soil, it has an effect for 10 to 100 years, significantly improving soil quality in the long term.

Biochar has the unique ability to store microorganisms, microelements (e.g. Fe, Br, Cu, Ph, Mn, Mg), which contributes to increasing soil fertility and microbial activity. It can also retain large amounts of water in the soil due to its high porosity. In applications of 250-500 g/m² it helps to condition the soil. The effect of biochar is immediate and multiple when activated with wood vinegar.

Biochar also provides effective protection against plant pests and fungi. It stores microelements, improves the soil bacterial environment, improves soil water retention, helps soil aeration and reduces nitrous oxide and methane emissions. 1kg of Biochar sequesters 3.5kg of CO₂ in the soil, reducing carbon dioxide emissions. GEKKA Biochar and Biochar+ Plus are tested and ecologically certified multi-winning products. In 2019, the European Union also authorised the use of Biochar (bio-char) in industrial agriculture.
