Rubber Research Institute of India (RRII), Rubber Board in collaboration with National Bureau of Soil Survey and Land Use Planning (NBSS & LUP), ICAR undertook a detailed survey of rubber growing soils of South India with an objective to bring the entire rubber area in the country within the ambit of soil test based fertilizer recommendation.

Soil samples were also collected using core samplers to determine the gravel content. Location coordinates of sites of soil samples were recorded by GPS. 

Soil samples were analysed following standard analytical protocols for soil pH, organic carbon and primary, secondary and micronutrients in the laboratories of RRII and NBSS & LUP and nutrient content in the fine earth fraction was mapped with geostatistical techniques, deriving a surface using the values from the measured locations to predict values for each location in the landscape by Kriging interpolation technique.

Browser and Mobile based fertilizer recommendation was developed based on interpolated soil fertility data in collaboration with Indian Institute of Information Technology and Management - Kerala (IIITM-K) overlaying different soil fertility parameters and soil depth following the guidelines of discriminatory fertilizer recommendation.
