Notes on the reclamation of salt-affected soils is the Indus Plain of West Pakistan.

Abstract

About 5, 500, 000 acres of cultivated land in the area are, to varying degrees, damaged by salinity and alkalinity due to waterlogging and under-irrigation in an arid, climate. Most juvenile sedimentary soils of the Indus Plain are calcareous and some of the salt-affected soils, especially in the south, are easily reclaimed because of their high content of divalent cations. In the north, much of the soil is difficult to reclaim because of alkalinity. These latter soils have very low contents of divalent cations, Ca- and Mg carbonates being the only source. Rapid and efficient reclamation will necessitate use of soil amendments. (Abstract retrieved from CAB Abstracts by CABI’s permission)
