This study was carried out in Erbil governorate, Iraq during 2020 to estimate the regression relations between the ionic strength of 354 water samples and their electrical conductivity then influence of correcting ion pairs and activity on this relation. Results indicated that electrical conductivity regards as an accurate measure of ionic strength...
The research was done in Erbil governorate, Iraqi Kurdistan Region in both times of sampling (June and October 2020) to determine a quality index of irrigation water (IWQI) for 354 water samples depending on (EC, SAR, CROSSo, MCAR, SP, RSC) parameters before and after correcting ion pairs and ion pairs plus activity. The results indicated the effec...

This study was conducted during 2020, The water samples were taken on June and October,2020 which were represent wet and dry season respectively from 22 springs in Erbil governorate. Some water chemical properties and heavy metals were determined at both wet and dry season, the studied spring waters were classified according to some systems or meth...
This investigation was conducted during January, 2018 to April, 2019 to investigate the role of correcting ion pairs and activity in decreasing the risk of saline water for irrigation. The groundwater of (31) wells in Makhmur district were depended in this study .The results indicated that amount of ions contributing in ion pairing was ranged betwe...
ABSTRACT
This study was conducted during 25/12/2013 to 20/5/2014 to study the effect of 15 water qualities (IWQI) on soil chemical properties, growth , yield and nutrient content of wheat, using Completely Randomized Design (CRD) with 4 replicates. The main results can be summarized as follow:
The electrical conductivity of the soil extract increas...
This study was conducted during the hydrological year of 2013, which included seasonal water chemical analysis for 53 wells in Erbil plain,classification and a pot experiment to study the effect of 15 water qualities on soil and wheat plant. Depending on Richards's classification (1954) the water for 30 wells located within (C 3 S 1) class, while t...
