Abstract EN

The results of applying some suggested systems for identification of soil series level under Iraqi pedological soils status, indicated the presence of some difficulties due to interaction between identified series which can belong to more than soil orders at the same time or one series can belong to more than one family.

This fact is due to not taken all common soil properties for the soils of the Mesopotamian plain.

The aim of this study is to fine a system allowing the systematic correlation between all soil classification levels with out any type of interaction between any soil taxon by using the most common soil properties as differentiation criteria between soil taxon Number of the most common and dominant soil properties were selected as differentiated criteria to classify soil series level for soils of the Mesopotamian plain.

The control section for the series level as suggested by US system and applied in Iraq, was followed in this study.

The control section was divided to three pats in order to avoid the stratification which is very common criteria in the soils of the Mesopotamian plain.

The differentiated properties for the family level which belong to one family and have a relation to soil management were used in this study.

These properties include: soil texture class, drainage class, cracking, soil structure, salt accumulations hard pans and buried status.

In order to have a good correlation between all the classification level, the symbol of the order level was used as a part of the series name
