Soil salinity is a major problem in canal command areas which affects the fertility of the land. The village Ugar Budruk in Athani taluk of Belgaum district in Karnataka faced a major challenge of soil salinity and waterlogging since 25-30 years. Approximately 70 per cent of cultivable area of the village was affected by soil salinity and the land which was highly productive once, was partially cultivated or left barren for many years. With the effort of progressive farmers of the village about 925 ha saline land has been reclaimed through installation of subsurface drainage technology. The per hectare cost of land reclamation was estimated to Rs. 52000. The post reclamation study implied that about 77 per cent of the land was non-saline. The mean soil salinity was reduced from 6.6 to 2.52 dS/m during post-SSD showing 163 per cent reduction in soil salinity. The improved land productivity contributed to a significant increase in crop yield due to increase in farmers income to a maximum extent. The pre-SSD benefit-cost ratio of 0.56 and 0.51 were increased to 1.24 and 1.19 during post-SSD, respectively for planted and ratoon sugarcane production. The increase in benefit-cost ratio for planted and ratoon sugarcane production were about 120 and 134 per cent respectively. Though the installation of saline soil reclamation technology requires high cost, the effectiveness of the technology made the Karnataka farmers to install the technology on their own cost.
