Abstract
The distinguishing characteristic of saline soils contains sufficient neutral soluble salts to adversely affect the growth of most of the crop plants. Saline soils are those which have an electrical conductivity of more than 4 dS/m at 25 °C. Different ways of saline soil reclamation practices were followed to alleviate the saline soil problem and the practices encompasses namely, scraping, flushing and leaching, agronomic practices, crop rotation, selected crop cultivation, different irrigation practices, drainage of soil, gypsum application and biological methods of saline soil removal by applying manures, green manures and bulky organic manures, etc.
