A study was carried out to estimate the extent of rubber area with high status of soil organic carbon (SOC) and soil depth greater than one meter to calculate the net savings by skipping chemical fertilizers in such holdings in the traditional rubber growing regions of Kerala and Kanyakumari district of Tamil Nadu using geo-spatial approach. Satellite-derived rubber plantation maps, SOC and soil depth maps were used for the present analysis. Thematic layers of SOC and soil depth were taken from the data base of Rubber Soil Information System (RubSIS) developed recently by Rubber Research Institute of India. The extent of rubber area with high soil OC status having a depth of more than one meter were delineated using spatial overlay analysis. Regions qualifying for this dual criteria were considered to estimate the net savings, including fertilizer cost and labour charges. Results indicated that in 1,61,911 ha of mature rubber area in Kerala and Kanyakumari district of Tamil Nadu, fertilizer application can be skipped for short periods which accounted for a net annual saving of Rs. 87 crores per year. District-wise interpretation revealed that net annual savings was the highest in Kottayam district (Rs. 27.4 crore per year) and in all other districts net annual savings would be below Rs. 10 crores per year. Geo-spatial analysis was helpful in identifying mature rubber area where fertilizers can be skipped for short periods which could reduce the cultivation cost and avoid unnecessay pollution.
