The work aims to present the soil covering outside the built-up area of Zăbrani commune. The studies were carried out over a period of 3 years, respectively the years 2021-2023. The commune of Zăbrani, in Arad County, occupies a total area of 11,778 ha. The soil cover is mostly represented by eutricambosols, luvosols and preluvosols. The largest area is represented by preluvosoil with over 74%, followed by luvosoil. Following the results obtained, it was found that the preluvosoil has a medium fertility, being characterized by the following properties: a fine texture, undifferentiated on the profile, the density has values between 2.67-2.72 g/m3; the apparent density, between 1.36 and 1.52 g/cm³, the total porosity has high values, of 50% and 43% at the level of the Bt layer, CC is between 23.72 and 24.74% and CT between 28.34 and 36.76. The soil has a husum content of 2.33% at the depth of 0-22 cm and decreases to 1.53% at greater depths. The nitrogen index is 2.15% at ad. 0-22 cm (mean values), the mobile K index between 207.5 ppm in the Ap horizon and 182.6 ppm in the Btyw horizon and the mobile P index is high, with values between 63.3 ppm and 117.3 ppm. Luvosoil is characterized by the following properties: the texture presents accentuated differentiations from one horizon to another, from clay-dust in El, medium in Bty and clay-clay in the rest, the reaction is weakly acidic on the surface, neutral in Bt and weakly alkaline in Cyw (5.29-8.09), the humus content is low and very low, 1.61 in El, respectively 0.72 in Bty and the degree of saturation in bases above 77%. Knowing these properties helps us to characterize the soils in general, to establish the crops that are suitable and to take improvement measures, where necessary.
