In this paper the status of sodic-saline soils of the Ararat Plain of Armenia is considered and classification of these soils is presented. In a country with limited soil resources the saline-sodic problem is very important. It is shown that former methods of their amelioration can not be used at the present time. Different soil amendments and methods of their utilization are considered. The possibility of applying dilute water solutions of magnesium chloride is discussed. The advisability of using this amendment is conditioned by the fact that this material is a byproduct arising from the processing of magnesium rich ultramafic rocks. A complex for processing of such rocks in Armenia and metallurgical plant for obtaining different metals and their compounds will be operational in the near future.
