ICAR - National Bureau of Soil Survey and Land Use Planning

  1. 1. S.K. SINGH Director ICAR-NBSS&LUP, NAGPUR ICAR-National Bureau of Soil Survey and Land Use Planning Amravati Road, Nagpur  NBSS&LUP- In the service of nation since 1976  Five regional canters: RC Kolkata, eastern region RC Jorhat, north eastern region RC Delhi, northern region RC Bangalore, southern region RC Udaipur, Western region
  2. 2. 2 Mandate  To conduct soil survey and mapping of the soils of the country to promote scientific and optimal land use programmes in collaboration with relevant institutions and agencies.  To conduct and promote research in the National Agricultural Research System in the areas of Pedology, Soil survey, Remote sensing applications, Land degradation, Land evaluation and Land use planning.  To impart training and education to create awareness on soil and land resources and their state of health.

  21. 21. Market based Land Use- The driver Lack of Land use based market Telangana, Andhra Pradesh and Tamilnadu- Maize area with support of poultry industry; cotton is being replaced Groundnut- Gujarat; Sugarcane- Maharashtra and U.P Bihar- Potential area for maize, lack of processing unit; farmers do not have interest Assigning the reasons for degradation

  23. 23.  Sustainable agriculture includes sustainable area with the area specific best management practices (BMP) covering soil conservation measures for water harvesting in the rain-fed areas, the best water management in the irrigated areas and nutrient management in site specific mode.  Sustainable area (SA) is an uniform piece of land, potentially suitable for a crop and cropping sequence in terms of soil, water and climate, presently available for the defined use. Scale: National, Regional, State, district, village and farm Conceptualizing Sustainable Agriculture
