Microbial solutions for cotton stalk composting - Innovation @ E2Expo
Updated : December 2020
Cotton stalk burning, while it is a must, has its own challenges and composting is difficult owing to their woody nature. Conventional cotton waste composting takes about 3 to 6 months depending on the process conditions.
In this regard, ICAR-Central Institute of Research for Cotton Technology has developed a microbial consortium technique to accelerate the composting process. The new solution takes about 45 days for wet stalks and 60 days for dry stalks.
With the new solution, the compost has a higher NPK value, thus enhancing the soil health. It also reduces the need for chemical fertilizers and prevents burning of cotton stalks in the field, thus creating a positive environmental impact. On the economics, use of cotton stalk compost results in significant savings owing to the requirement of less quantity compared to conventional compost.
ICAR-Central Institute for Research on Cotton Technology (ICAR-CIRCOT) is one of the premier constituent institutes of the Indian Council of Agricultural Research (ICAR), under the Department of Agricultural Research and Education (DARE), Ministry of Agriculture, Government of India.
Its objective is to assist cotton breeders in the development of new strains by evaluating various fibre quality parameters and carrying out research on their spinning potential.
