An experiment was conducted in pots to evolve a suitable technique for reclamation of a sodic soil by using high-salt water dilution method in conjunction with usual amendments such as farmyard manure and gypsum. The total removal of sodium in the effluent was more with the treatment of farmyard manure plus gypsum and leaching with high-salt water as sufficient amount of Ca2+ was released (from gypsum) to replace Na+ from the soil complex. The dry-matter production of maize in sodic soil reclaimed in this manner was the highest besides higher reclamation efficiency as compared to all other treatments.
