This paper presents a description of the main soil types and sub-types outside Voiteni, Timis County, Romania. (8) To do so, we used data from our own observations during field work, data from previous studies, as well as data from the Voiteni town hall and from O.S.P.A. Timisoara. (10) On the studied territory, we identified poor, alkaline Gleyey chernozem; loamy, low-levigated chernozem; vertic, stagnogley preluvosol; and mollic, moist phreatic preluvosol. These soils are described depending on their physical and chemical features: texture, density, apparent density, total porosity, aeration porosity, reaction, humus content, carbonate content, and base saturation level, using the classical methods or different calculus formulas. (7) These soils are at the interference between the low plain from Jebel, Ciacova, Ghilad, and Banloc with the high plain corresponding to Lieblieng, Folea, and Gătaia, which produced an uneven relief with slopes of 1-5% from east to west and south-west. The mean altitude of the area tanged within 92 and 108 m. (1,4) Lithologically, the commune of Voiteni is characterised by a succession of strata of different age, thickness, and granulometric structure, depending on the meso- and micro-relief conditions. In general, both the subjacent rock and the parental one has a variable content of CaCO3, and some of them have a high content of natrium as soluble salts or natrium carbonate (sodium muds). This, together with ground water at low depth and intensely mineralised have contributed to the genesis, in the low plain, of saline and alkaline soil types and sub-types. (5) The depth of the ground water in the low plain area corresponding to depression areas ranges between 0.5 m and 3 to 4 m in the higher areas. This caused the formation of gley, stagnogley, and moist phreatic soil sub-types. (2,6)
