What is biochar?<\/p>\n
Biochar is a fine-particle coal like substance that can be used as a soil amendment to improve soil health, it is high in organic carbon and also resistant to degradation. It is made through a controlled process called pyrolysis by burning of organic material from agricultural and forestry wastes
\nwhere the organic materials like leaf litter, dead plants or chips of wood are burned in a container with little oxygen. It is called as Black gold of Agriculture.<\/p>\n
Preparation of biochar:
\nPyrolysis: This is the most common method of biochar preparation. It is also known as thermal decomposition under oxygen free conditions. It involves heating of organic materials to the temperatures greater than 4000 C by electric heating or high temperature under inert atmosphere.
\nOther methods of biochar preparation include:
\n\uf0b7 Hydrothermal carbonization
\n\uf0b7 Microwave carbonization
\n\uf0b7 Flah carbonization
\n\uf0b7 Torrefaction
\nThere are various parameters present which influence the physiochemical properties of biochar like raw material, heating rate, reaction temperature, reaction atmosphere etc.<\/p>\n
What is the role of biochar in agriculture?<\/p>\n
\uf0b7 Application of biochar to the soil increases the nutrient availability and uptake of nutrient by the plants.
\n\uf0b7 Biochar plays a key role in carbon sequestration in the soil and also in returning the organic matter which is lost in biomass removal from agricultural or forestry systems through energy production.
\n\uf0b7 It has the capacity to improve the agronomic and environmental sustainability of biomass production systems.
\n\uf0b7 As the biochar is a porous material it helps in adsorbing and retaining huge amount of water. Thus, improves the water holding capacity of soil.
\n\uf0b7 Biochar application increases the soil ph.
\n\uf0b7 Different types of biochar are present based on the composition and material from which they are derived.
\n\uf0b7 It helps in improving the cation exchange capacity of soil.
\n\uf0b7 It reduces the leaching of nutrients.
\n\uf0b7 It stimulates the symbiotic nitrogen fixation in case of legumes.
\n\uf0b7 It supports soil microbial life and biodiversity.
\n\uf0b7 It enhances plant growth.
\n\uf0b7 It helps the plants to resist various pests and diseases.
\n\uf0b7 It provides soil enhancement that lasts a lifetime.<\/p>\n","protected":false},"excerpt":{"rendered":"
