The decomposers are in the form of capsules made by extracting fungi strains that help the paddy straw to
decompose at a much faster rate than usual.
The decomposer improves the fertility and productivity of the soil as the stubble works as manure and
compost for the crops and lesser fertilizer consumption is required in the future.
It is an efficient and effective, cheaper, doable and practical technique to stop stubble burning.
It is an eco-friendly and environmentally useful technology and will contribute to achieve Swachh Bharat
It hastens the rate of decomposition of various Agriculture waste
Pusa decomposer helps to prepare compost in pits, heaps and windrows as well as in the field for
degradation of agriculture residue.
How to use:
The process of forming the solution would take a total of 12 days. Firstly, 150 gm of jaggery has to be
mixed in five litres of water and boiled, once the solution cools, 50 gm of gram flour has to be added it.
The capsules are then mixed into the solution and kept in a container with a broad surface area, and allowed
to grow for four days. A thick mat of fungal mycelia and spores will grow, after the first four days,
another five litres of water and 150 gm of jaggery are boiled, cooled and added to the first solution and
left for two days. This step is repeated another three times every two days, increasing the quantity of the
solution to 25 litres.
This 25-litre-solution is then added to 475 litres of water. The total 500 litres are sufficient only for one
hectare and is sprayed on the paddy straw/ agricultural waste after the harvest has been completed. The
spray could either be left on the straw or mixed with the soil using a rotavator, a machine used to prepare
the seed bed on farms. The fields can also be irrigated if the moisture is not sufficient. After this, the
surface is left for 25 days. In 25 days, the stubble/ waste will be completely decomposed by fungal action.
It will become very soft and then farmer can plough the field and it will be ready for sowing wheat or any
