Biochar is anhydrous charcoal, a by-product produced during the gasification process, the characteristics of which depend on the ash properties of the biomass used.
It is a stable, compact and “durable” carbon and can store large amounts of greenhouse gases in the soil for centuries, potentially reducing or reducing the increase in greenhouse gas levels; at the same time its presence in soils can improve water quality, increase soil fertility and increase agricultural productivity.
For plants that require high potash content and increased pH, biochar can be used as a soil conditioner to improve crop yields. Biochar can also improve water quality, reduce greenhouse gas emissions from the soil, reduce nutrient leaching, reduce soil acidity and reduce irrigation and fertilization needs.
Research has also shown that biochar, under certain conditions, can cause plant systemic responses to fungal leaf diseases and improve plant responses to diseases caused by soil pathogens. The continued growth of this market (forecast for global growth of more than 15% per year over the next decade), in line with the continuing deterioration of cultivated soil due to systematic and industrialized agriculture, shows that there is an urgent need for products with similar benefits such as biochar. In addition, the increased demand for organic products enhances the attractiveness of biochar to new producers / farmers, whose promotion will be supported through information campaigns for farmers and will highlight the benefits of their production.
