Nagpur: The government is planning an organic revolution for the country, and the ICAR-National Bureau of Soil Survey and Land Use Planning (NBSS&LUP) has come to its aid by identifying areas holding high potential for the same.
After completing scientific research that started in 2011, the bureau along with ICAR-Indian Institute of Soil Science, Bhopal, and Food and Agricultural Organisation (FAO) has prepared a geo-spatial digital map showing organic carbon stock in the soils of all states.
During the research, two lakh soil samples from all over the country were collected and analysed for determining the content of organic carbon. “Organic farming will give best results in areas having high quantity of organic carbon, which is a rich source of nutrients. In conventional farming, urea, nitrogen, phosphorous, insecticides and pesticides are used. But in organic farming, only natural manure is used and thus soils with adequate nutrients as evidenced by high organic carbon content are likely to produce high yield,” said Surendra Kumar Singh, director of ICAR-NBSS&LUP.
The map shows that parts of Kerala, Karnataka, Goa and Maharashtra, also falling under the Western Ghats, possess rich organic carbon and are ideal for organic farming. In northern India, Himachal Pradesh, Chandigarh, Uttarakhand and parts of Jammu and Kashmir are the best zones to support organic farming. On the other hand, states like Punjab, Haryana, Uttar Pradesh and West Bengal have low potential for organic farming due to “intensive cultivation”. Singh said, “In case of intensive farming, nutrients are mined from soils without adequate replenishment. This results in the depletion of organic carbon.”
