SALINE SOILS IN THE SOUTHERN PART OF THE ARARAT VALLEY: EXPERIENCE OF MAPPING BY LANDSAT-8 DATA
Journal Title: Наукові доповіді НУБіП України - Year 2018, Vol 4, Issue 4
Abstract
The distribution of saline soils in the southern part of the Ararat valley is considered in connection with the prospect of agriculture intensifying there. For an approximate assessment of the saline soils localization, satellite images of Landsat-8 with a resolution capacity of 30 m were used. Of the total area of the investigated territory, 111809 hectares, the plain part itself occupies about 75 thousand hectares, and the area of saline soils is 21503 ha. Consequently, within the plain part of the valley, suitable for agricultural use, saline soils, that require hydraulic engineering and (probably) chemical reclamation, occupy 28.7% of the area. Saline soils are least widespread in the western part of the plain, and most - in the central part at the foot of the Ararat Mount. In the eastern part, saline soils alternate with hydromorphic (overmoistened) soils.
