The purpose of the research is to study the soil cover of the Sanaa basin, identify patterns of distribution of soil differences depending on natural conditions as factors of soil formation, classify soils, determine the suitability of soils for agricultural use and establish the need for various land reclamation to prevent or eliminate the impact on the soil of negative natural or anthropogenic processes. The main method of research is conducting an area soil survey and setting up key experimental sites where morphological description of soil sections, determination of physical, water-physical and laboratory conditions was carried out.
