Interspersed Salt-Affected and Unaffected Dryland Soils of the Lower Rio Grande Valley: I. Chemical, Physical, and Mineralogical Characteristics

Abstract

The effects of soluble salts on soil productivity are global. Recent reports present information about saline soils in Spain (1), Iraq (2, 7), Canada (6), Egypt (16), and the United States (8, 10, 15, 19). Although in some areas much has been done towards reclaiming saline soils (5, 9, 17, 19), in other areas plagued by salinity problems (1, 6, 7), little or no progress is eviden
