Abstract
This research was conducted with the purpose of studying some specific properties of irrigation water quality for artesian self-propelled wells in Wadi Shati region in southern Libya, and assessing the quality of chemical water properties and their suitability for irrigation. This study included 10 artesian self-propelled wells where the results showed that all the chemical properties of irrigation water were within the permissible limits of the Food and Agriculture Organization of the United Nations and the American Salinity Laboratory standards. except for potassium (K) that exceeded the permissible limits, where the results showed that the (K) concentration is between 0.51-0.59 meq/L, and the values of electrical conductivity ranged between 917-1035 s/m³µ, while the total dissolved salts were between 587-662 mg/L, also the exponent values The pH is between 6.9-7.7, while the sodium (Na) concentration is between 2.48-3.09 meq/L, and the calcium (Ca) results ranged between 0.6-0.9 meq/L, and the chloride concentration ranged between 4.37 and 4.90 meq/L, and these sulphate concentrations were between 1-2.54 meq/L, while the bicarbonate concentration ranged between 1.25-1.51 meq/L, The results of the basic indicators in irrigation water indicated that the percentage of sodium ranged between 49-59%, and the rate of sodium adsorption ranged between 2.45-3.45 meq/L, and the modified sodium adsorption ratio was 3.13-4.07 meq/L and the magnesium (Mg) risk ratio 43-67%, Thereby the water studied was classified as highly salty and low in sodium risk.
