A six-year ICAR study — one of the largest soil carbon assessments ever conducted — found declining organic carbon across India's arable land. The most affected states, Haryana, Punjab, western Uttar Pradesh, are the same ones where India's agricultural CBG plants are concentrated.
Every CBG plant produces fermented organic manure — a digestate that rebuilds soil organic carbon. The ICAR study of 254,236 soil samples across 620 Indian districts found that soil organic carbon is declining across large parts of the country. Digestate is one of the few scalable ways to reverse it.
