Production of Biochar Using Top-Lit Updraft and Its Application in Horticulture

Biochar is a charcoal, rich in carbon, produced by typically burning organic residues of plants and animals to more than 250 °C in a low-oxygen environment. It could be efficiently produced by the various methods, but the top-lit updraft (TLUD) method is the most affordable at each farm level in agriculture. Several controlling factors determine the distinctive quality of biochar; however, the agricultural application of biochar is precisely beneficial if applied appropriately. It increases the water retention capability of the soil and cation exchange rates and holds the nutrient-holding capacity and reclamation of acidic soils. Moreover, biochar could also endure an efficient way to sequestrate carbon and a valuable agent for sustainable agriculture.
