Biochar, a product manufactured through a technology with negative emissions obtained through the valorisation and superior use of agro-wastes, proves to have multiple uses (agriculture, environment, industry). The use in agriculture as an amendment or in the composition of some fertilizers that improve their nutrient supply properties contributes to the decrease of farmers' dependence on chemical fertilizers and the reduction of their application doses. This technology of using biochar supports farmers by combating soil degradation, increasing carbon content, simultaneously decreasing leached nutrients (especially nitrogen) and greenhouse gases, and decreasing the content of contaminants in agricultural products through the retention effect in the biochar structure of pesticides and heavy metals, which affect the production and quality of crops. At the same time, biochar represented a means of combating climate change, improving the physico-chemical properties of the soil and offering benefits to agricultural crops.
