The present research consists of a comparative study of three land assessment systems Land Capability Classification (LCC), s STORIE and an assessment system adopted by the National Institute of Soils, Irrigation and Drainage (INSID) in applying them to two ecologically different regions, namely: the High Plains (Sidi Bel Abbes) and a steppe region (Djelfa). According to the results obtained by the three systems, there is a similarity between the evaluation results of the three systems in comparison with the Sidi Bel Abbès region. The INSID rating system gave lower results compared to the other two systems, this is due to other soil properties that are only taken into consideration by INSID, such as the total lime content which is quite high for most cartographic units, the correlation between LCC – INSID is very highly significant p<0.001). Likewise, this relationship is significant between INSID - STORIE and highly significant (p<0.05) for LCC - STORIE. In order for the INSID system to be suitable for the contexts of Algeria and North Africa, some recommendations have been made. The reduction in the number of certain soil variables that are subject to evaluation, particularly those concerning interrelated properties. As is the case with pH and total limestone, if a soil has a high level of limestone it will have an impact on its pH at a certain limit.
