Reclamation of soils contaminated by sodium chloride.

Abstract

Soil samples contaminated in the laboratory with a NaCl solution were leached with water after various amendments had been added. Percolation generally increased as more Ca-amendment was added to the contaminated A horizons, but rate of (surface-applied) amendment had no effect on the percolation through the B horizon cores. Gypsum mixed into the contaminated soil was much more effective than gypsum applied on the surface.-after Author
