The study dealt with the evaluation of the characteristics of groundwater for agricultural irrigation، for 23 wells in the Sabba Qusour area، northeast of Baghdad، which has an area of ​​(13.35 km 2)، and a population of more than eighty thousand people، through the use of eight classifications، according to international standards، there are seven wells، only four are valid. For irrigation، it represents only (30%) of the wells of the study area، while the sodium absorption rate (SAR) is within category (S1)، which is low-sodium water that can be used in any soil، except for only one well (W 12) within category (S2)، which is water Medium sodium، while the Phipps classification is eight wells within the C4 category، with a rate of 35%، which is water with very high salinity and is not suitable for irrigation except for crops with high tolerance to salinity، and the soil needs continuous tapping operations and great care، and eight other wells within the C5 category، with a rate of 35% not It is suitable for irrigation. As for the classification of Na% sodium، we find that 92% of the well water is within the good category، while the residual sodium carbonate coefficient RSC is within the safe category، while the permeability index PI is within the Class-II class (appropriate)، and according to Richard’s classification 64% is within the category Poor، 63% inadequate، according to the Wilcox rating.
