Abstract

Three soil profiles from different date palm orchards in Al-Hassa were described and sampled by horizons. Some chemical and physical properties of the samples were determined. The three profiles were classified in the Entisol order of the Americal Taxonomy and are considered to be Orthents. All of the profiles had light texture in the topsoil and heavier texture in the substratum. The soils were calcareous and had low contents of organic matter, available P and DTPA soluble Fe. The contents of Cu, Mn And Zn were higher than the critical levels below which deficiencies are to be expected.
