Role of biochar on soil fertility improvement and greenhouse gases sequestration

Abstract

Biochar is mostly porous, stable C rich, formed at high temperature, highly serpent and nutrient rich material. The objective of this work was to understand the role of biochar on soil fertility improvement and greenhouse gases sequestration. Biochar application can improve soil fertility by manipulating soil properties that is soil porosity, soil water holding capacity, soil aggregation soil reaction (pH), soil organic carbon these soil physicochemical properties improved and the soil becomes safe nutrient rich to support plant growth. In addition biochar application increases the activities and population rhizobia species in the soil. Emissions of greenhouse gases were suppressed by application of biochar in agricultural fields. Soil contaminant effectively adsorbed, suppressed biodegradation and leaching of contaminants in to ground water. The efficiency of biochar’s depends on feedstock type, pyrolysis temperature. Biochar is the most eco-friendly technology that should be used for soil fertility improvement and reduced the emission of greenhouse gases.
