The Government of India established All India Soil Survey Organisation in 1956 with the Headquarters at the Indian Agricultural Research Institute with five Regional Soil Correlation Centres at Bangalore, Delhi, Kolkata, Jorhat and Udaipur. Later in 1958, this scheme was integrated with the Land Use Planning Scheme of the Central Soil Conservation Board primarily to carry out detailed soil surveys in the catchment areas of major River Valley projects, with setting-up the organisation, "All India Soil and Land Use Survey'.
