Chemical and Mineralogical Properties of Kufra Sahara Soils

الملخص

Chemical, physical; and mineralogical properties of Sahara soils from the Kufra oasis in Libya are presented. The minerals present in the soils consist mainly of primary minerals. Sand size seperates make up 85-90% of the mass. The soils exhibit no profile development, and are classified according to the U.S.D.A. soil taxonomy as Torrip-samments.
Sand lenses which occur within the root zone and restrict water movement and root penetration are not cemented but are due to particle size segregation.
