TAILIEUCHUNG - Biochar a source of C sink and soil health - A review

Biochar, a charcoal produced from biomass, can sequester carbon in soil for hundreds to thousands of years. Biochar is created by heating organic material under conditions of limited or no oxygen. Soil organic matter needs to be maintained and further increased to keep soil healthy. Biochar is extremely porous which allows it to retain nutrients and water and improved soil aggregate stability. The quality of biochar as a soil ameliorant depends on the feedstock and on soil type, temperature, and humidity. Converting biomass to biochar offers an excellent method for waste management and using these byproducts for the improvement of soil quality and productivity. | 2018 7 4 3622-3631 EXCELLENT PUBLISHERS International Journal of Current Microbiology and Applied Sciences ISSN 2319-7706 Volume 7 Number 04 2018 Journal homepage http Review Article https Biochar A Source of C Sink and Soil Health-A Review Peeyush Sharma1 Vikas Abrol2 Neetu Sharma3 and Shrdha Anand4 division of Soil Science and Agricultural Chemistry SKUAST-J Chatha-180009 India 2ACRA Dhainsar SKUAST-J Chatha-180009 India 3Division of Agronomy SKUAST-J Chatha-180009 India 4GGM Science College Jammu-180001 India ABSTRACT Keywords Biochar Soil biological properties Carbon sequestration Crop productivity Article Info Accepted 28 March 2018 Available Online 10 April 2018 Biochar a charcoal produced from biomass can sequester carbon in soil for hundreds to thousands of years.

Introduction Biochar refer to the carbon-rich materials charcoal obtained from the thermo-chemical conversion of biomass in an oxygen- limited environment pyrolysis . Biochar was first found in the Central Amazon basin. Applying biochar to agricultural soils is considered to improve carbon sequestration and decreased greenhouse gas emissions from agriculture. Recently biochar has gotten attention of researchers because of its capacity to improve water-holding capacity and nutrient-holding ability of soil because of its porous structure high specific surface area and .
