Biochar is a valuable product that is produced through the pyrolysis heating of organic matter. The properties of biochar are strongly influenced by the temperature used during the production process, the length of time the material is exposed to that temperature, and the production vessel used. High production temperatures result in more porous biochar particles that have a proportionally greater surface area, Cation Exchange Capacity (CEC), and a higher pH. The physical and chemical properties of biochar products also vary widely due to differences in the production processes and the plant species used. The application of biochar can have a positive impact on crop yield and nutrient availability, particularly in tropical acidic soils due to their low fertility. Biochar can be matched to the soil or substrate and crop requirements to achieve the desired results. Additionally, the cost of biochar amendment to a field soil or container substrate can provide additional value by reducing crop production costs and providing long-term environmental benefits. Biochar is a sustainable and cost-effective product that can provide many benefits for agricultural and environmental purposes.
