Abstract: Ten soil profiles were selected to represent the main geomorphic units in the western side of the Nile Delta in order to evaluate their physical and chemical properties of these soils to be classified, land capability for cultivation as well as land suitability for growing crops were carried out. According to the Taxonomic system (2010), the soils could be classified into three orders (Vertisols; Aridisols and Entisols) and five sub orders (Aquerts, Torrerts, Calcids, Psamments and Orthens) and their degradation up to the salinity levels ( i.e. seven families). The current suitability of the studied soils could be categorized into two suitability classes [i.e. moderately (S2) and marginally suitable (S3)]. The studied soils are affected by many of limiting factors, i.e. texture, salinity and alkalinity and calcareoresness with variable intensity degrees. Land suitability for certain crops can be achieved by matching the ratings of land characteristics with the crop requirements in different suitability levels as proposed by Sys et al (1993). The obtained data of soil suitability for same selected crops (16 crops), which are presented for the studied the studied soils developed on the identified geomorphic units as land suitability guide tables, reveal that the current suitability classes of the studied soil profiles include all the suitable classes (S, S, S and N).
