The study locations were chosen within the central Euphrates regions, which include the provinces of (Babylon, Diwaniyah, Karbala, Najaf, and Muthanna), which lie between longitudes 31.2926 to 32.9055 north and latitudes 44.0332 to 45.3845 east by UTM system, and 15 pedons  were detected, Three pedons in each province, two for cultivated soils and One because five regions and three pedons for each region pedons for abandoned soil. Fertility traits results showed that the available nitrogen value ranged from 50.11 -15.51 mg kg^-1,As for available phosphorous in the soil, it ranged between 27.22-7.76 mg kg^-1, and the values ​​of available potassium ranged between 162.4 - 80.37 mg kg^-1. These available nutrients in the soil showed a difference between little, medium and high. The highest variance was the available nitrogen, followed by the available phosphorous and available potassium. As for the effect of agricultural use and location on soil traits, the results showed that the bi-interaction between the type of use and location had a significant effect.
