Importance of bio-char in climate change mitigation and stress crop production

The major limiting factors effecting crop productivity are climate change and abiotic stress mainly drought. Abiotic stress persistently checks the crop selection, crop production worldwide and reduces yield, under extreme conditions it leads to entire crop failure. Under these adverse conditions a shift from traditional agricultural practices like on-farm burning of crop residues to new technologies which can reduce green house gas (GHG) emissions and stress effect on crop production is mandatory. Bio-char incorporation into soil is the probable justification for alleviating drought and GHG emissions. The porous nature of bio-char helps in improving the water holding capacity of soil, thus reducing the effect of drought on crop production. Bio-char incorporation not only alleviates stress but also improves physical, physico-chemical and chemical properties of soil. It is a trending technology which is economical, eco friendly and feasible to farmers for getting stable production under stress conditions and is suitable to any adverse conditions.
