Biochar is charcoal used as a soil amendment for both carbon sequestration and soil health benefits. Biochar is a stable solid, rich in carbon , and can endure in soil for thousands of years. Biochar is under investigation as a viable approach for carbon sequestration , [1] as it has the potential to help mitigate global warming and climate change. Independently, biochar can increase soil fertility of acidic soils low pH soils , increase agricultural productivity, and provide protection against some foliar and soil-borne diseases. Pre-Columbian Amazonians are believed to have used biochar to enhance soil productivity. These communities produced biochar by smoldering agricultural waste i. Biochar is a high-carbon, fine-grained residue that is currently produced through modern pyrolysis processes; it is the direct thermal decomposition of biomass in the absence of oxygen preventing combustion , which produces a mixture of solids the biochar proper , liquid bio-oil , and gas syngas products.

European Journal of Soil Science0. Archived from the original on 13 September Nature Communications. Al corresponding to 0, 66 6.

Biochar is a carbon rich charcoal that is formed by the pyrolysis thermal decomposition of organic biomass or agricultural residues which is used as soil amendment Xiao et al. Biochar is primarily composed of stable aromatic carbon ring structures Al-Wabel et al. ECI Digital Archives. The physical and chemical properties of biochars as determined by feedstocks and technologies are crucial for the application of biochars in the industry and environment.

International Biochar Initiative; Victor: Influence of heating temperature and holding time on biochars aplications from rubber wood sawdust via slow pyrolysis. Harsh, Nehal I. The combined spectroscopy-microscopy approach revealed the accumulation of aromatic-carbon in discrete spots in the solid-phase of microaggregates and its co-localization with clay minerals for soil amended with raw residue or biochar.

Hockaday, M. Monoj Bardalai, D. Retrieved 22 August As suggested by various researcher and research group the surplus crop residue could be used for alternative activities including biochar making instead of burning in the fiel.

Bioresource Technology

The following information was supplied regarding data availability:. All average data and standard deviation values are included in the article. Raw data are available in Data S1. Biochar, the product of biomass pyrolysis, has been explored as a soil amendment and carbon capture vessel. Recent literature has aligned biochar as a novel sorbent for a host of environmental contaminants. Through the variation of pyrolysis conditions, biochars can be engineered to have qualities desirable in sorbents whilst maintaining their agronomic benefits.
