Webum, saline soils generally are flocculat- ed. Their tillage properties and per- meability to water therefore are equal to or higher than those of similar non- saline soils. The abnormally high salt concentration of the soil solution of saline soils, however, reduces the rate at which plants absorb water; conse-quently growth is retarded.
