Abstract
This research aims to evaluate and the efficiency of the qualitative characteristics of the water and the extent of its suitability for agricultural purposes in the south of Wasit Governorate, which suffers from the scarcity of surface water. The study adopted a descriptive analysis method, where (7) samples of Al-Mabaz were collected in (East Al-Graf, West Al-Graf, Al-Mazak, Hawar, Wasit District, Al-Muwafaqiya District, Al-Husseiniya) and analyzed compared with the American standards allowed for irrigation and its organization (FAO). It showed the most important crops capable of withstanding the salinity of water, including barley, alfalfa, cotton, as well as palm trees. As for the effect of solids, their height leads to osmotic stress, and the percentage was in the mazak, Hawar, Al-Hussina and Al-Muwafiya, agriculture can be done with their water only, either calcium, all values were higher than the upper limit, only the dialogue and the Husseini mals were within the upper Sunday, either magnesium, all the ratios were within the ideal limit, according to the FAO. Either the sodium values ranged from (350) mg/l as a value in the mazak perforator and (768) mg/l, and sodium was high from the upper limit, so it is allowed to cultivate specific crops. The differences in the values of sulfates, as the highest value of sulfates in the East Al-Graf perforate was worth (2365) mg/l and the lowest value in a dialogue perforator (1208) mg/l, and the percentage of sulfates rose to double the normal limit. Either potassium, all the most suitable for agriculture, according to the organization (FAO). All the concentrations of the water of the study area are within the safe range and less than the maximum limit of the tubidity of more than (50) mg/l within the standards of the organized (FAO).
