Saline soils can be reclaimed by the application of a large amount of good quality water. The soluble salts leach down with percolating water.
Sodic soils can be reclaimed by the application of gypsum through broadcasting. Mix gypsum thoroughly in the soil and then flush with water. The calcium in gypsum replaces the sodium ions which leach down through applied water and induce a great impact on the plant’s growth.
