Reclamation of saline clay soils in the Tina Plain, Egypt

Trials designed to evaluate the most appropriate procedures for leaching hy per-saline clays covered by a salt crust within the Tina Plain, Sinai, Egyp t are described. These involved either continuous or intermittent pending o f water on the surface, commencing with brackish water, later followed by s imulated irrigation water. The results confirm that the soil salinity can b e dramatically reduced, but for greatest effect requires the removal of the surface salt crust at the outset.
