The paper presents the main properties of the mollic psamosols from the left bank of the Jiu River, starting from the climatic conditions, the lithology of the area, hydrography, hydrology, natural vegetation. The research included the documentation, field and laboratory stages. This type of soil has somewhat better relations with water and air, is richer in the colloidal complex, in humus and nutrients, for this reason it has somewhat higher fertility compared to other sandy soils. Based on these properties and the natural conditions in the area, bonitation grades can be assigned and classes of favorability can be established for different crops. It should be taken into account that in the climatic conditions of recent years in Oltenia, in order to improve the mollic psamosols, a series of measures must be taken, including: deep loosening, enrichment in humus and clay, application of organic and chemical fertilizers, but especially the completion of the moisture deficit through irrigation.
