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.

Highlights and sustainability benefits

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.

About the Work

The process involves using microbial consortium for the composting process. The cost to be incurred is Rs. 2.5 lakhs per village having 1000 acres of cotton cultivated land for purchasing one chipper. If tree shaded place is not available, shed may be erected as per the required capacity. The cost of operation per unit size is Rs. 2960 per tonne of compost. The benefit cost ratio is 1.08. There will be a saving of Rs. 9000 per ha by replacing FYM (12 tonnes) with cotton stalk compost (5 tonnes).

About the Innovator

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.
