The heavy smog and pollution that covered the nation's capital Delhi over the past few months were partially blamed on crop stubble burning in farms in Punjab and Haryana, to which neither of the governments had any solution.

A School of Environmental Sciences professor at the renowned Jawaharlal Nehru University has come up with a beneficial solution to the problem of stubble burning, which would not only reduce pollution, but would also benefit the farmers.

According to Professor Dinesh Mohan, leftover crop stubble 'biomoss' can be converted into Biochar using a reactor. Biochar, a manmade charcoal material is composed of agricultural wastes and can be re-used in the fields for agricultural purposes, to provide essential nutrients to the soil.

"One of the contributors to pollution in Delhi is stubble burning. Farmers do not have a solution to deal with waste. After working on the situation we found a solution where we can convert stubble or biomass into Biochar which can be used in agriculture," Prof. Mohan said.

Professor Mohan highlighted that the cost of this conversion is very less and the reactor can be made easily in their fields using mud. He added that one thing to keep in mind while using the reactor, is the amount of oxygen available and the entire process would take 24 to 48 hours.

"Biochar is a useful product, which can stay in the soil for several years thus benefiting farmers in the long run. It will enhance nutrients in the soil, boost its water holding capacity and productivity. It is a low-cost technique," he said.
