The aim of this study is to determine Soil quality standards that can be used to develop a better soil quality index that can be relied upon for future evaluation.Three different methods which varied criteria were used to choose soil quality index for some soils of the middle Euphrates plain. (parent material, slope, texture, gravel and stones, drainage condition and soil depth ) used a criteria to explain morphological soil quality index . physical soil quality used a criteria (structure, texture and consist) ; while chemical quality used (EC, lime, Ph and % organic matter) and, Results showed physical soil quality index varied between (0.47-0.79) with rang 0.32 ; and the series varied within class at rang 0.11. Morphology soil quality index varied between (1.29- 1.61) at rang 0.32 and soil series varied at 0.16. Soil chemical quality index varied at rang 1.20-1.59 and the soil series varied at rang 0.10 within class. Soil series distributed between high quality to low quality.
