Government priority in doubling of farm income of historically low yields in semiarid tracts of Karnatakais focused on enhancing the efficiency in crop productivity and natural resource use. Land resourceinventory is basically aimed at deriving comprehensive information on natural resources for designingmicro level land use planning and for enhancing land productivity and farm income. In view of this, anattempt was made to explore the economic viability of generating the soil survey information (1:12,500scale ) to minimize the cost of production thorough site specific nutrient management in Garakahallimicrowatershed, Karnataka State. The results showed that the per hectare cost of improved method ofsoil survey (using PAN+LISS III imagery) is ` 264 over conventional method of soil survey costing `337. Improved method of soil survey can minimize the cost up to 22 per cent in field survey. The economicviability of soil map was assessed by estimating fertilizer requirement with and without soil information.The impact in change in fertilizer application of finger millet production on the basis of soil informationcan reduce application of nitrogen by 5265 kg and phosphorus by 4661 kg and improvement of 1054quintal of yield with economic benefits of ` 8.43 lakhs in the watershed area of 527 ha. The study foundthat the benefits of soil survey in site specific fertilizer management in finger millet with the Benefit CostRatio 1:2.85 and the additional income due to soil management of ` 1600 per ha. The soil information isuseful in minimizing fertilizer cost and in enhancing farm income. The investment in soil survey andfertility management is economically viable at watershed level.
