Abstract:
Biochar is a carbon product while the raw materials, like forest, animal compost, and plant residues, and is heated in a closed storage place under anaerobic process. It is distinguished from charcoal by its use as a soil amendment. As a soil amendment it offer several benefits, which include increased soil texture, soil carbon, nutrient retention, and cation exchange capacity, beside support to microbial diversity and it also suppress disease infestation on various crops. The overall process is known as pyrolysis. Biochar quality from different sources is determined by the potential carbon sequestration, CO2 reduction potential and physicochemical properties. During biochar production the most important considerable’s includes up to 90% on feedstock type and temperature levels are the main characters. For agricultural purpose Biochar contributed as moderately contemporary improvement, evolving in combination with soil managing, carbon confiscation or sequestration matters, and immobilization of contaminants. Also, several studies observed that biochar amended soil help proliferate plant growth promoting rhizobacteria/fungi. The environmental advantage of biochar can relieve climate change through soil fertility improvement; enhance its structure, water penetration and aeration as well as decreases synthetic fertilizer and pesticide utilization and greenhouse gases emission reduction. Areas with enough vegetative covers by the contribution of the above soil hydrological and environmental properties will have crucial role for the environmental safety of particular areas.
