Evaluation the Suitability of Irrigation Water in Karma Island for Agriculture

Abstract To evaluating the suitability of surface and groundwater which used in agriculture Karma Island Anbar Governorate, eight wells depending on topographical variation area as well water (Euphrates River) were selected. The samples collected during winter summer seasons at period 2021-2022. tests included some chemical measurements water, its classification, assessment for agricultural purposes quality according to Baber classification. results showed significant difference between sources date sampling terms studied indicators, rates electrical conductivity ranged 1.20-12.05 dSm-1 values degree reaction general was tend towards equality (6.9-7.3). reason spatial temporal this indicators refer geological rocks from these ground waters pass through. As salinity is concerned, all within sever category, indicated magnitude use agriculture, because proportion exceeds limits characteristic, while resources light moderate category. In do not exceed recommended index manual. content calcium, sodium, chloride sulfate, outside usual range magnesium concentrations permissible limit, bicarbonate slight permeability no objection agriculture. Classified, class C4, sodium hazards, irrigation sites W1, W2, W3, W4, W5 low S1, W6, W7, W8 W9 class. S2. According geochemical properties basis Cations, it became clear that there sovereignty Na+ Ca+2, anions, chloride-sulfur water.
