In the present paper, an analisys is made on the main soils found in the forest area of the plains of the Banat region, respectively within the range of Timișoara and Lunca Timișului forest districts. Onwards, some correlations were made between the soils and the forest sites, the natural fundamental forest types and finally the optimal forest compositions (aim compositions) from the forestry point of view. Geomorphology, geological conditions, soil and climate, generally determined by the geographical and altitudinal location of the study district, favored the development of a varied and valuable forest vegetation, corresponding to the existing vegetation floors. The lithological substrates have led to the formation, in the vast majority of the surface, of luvisols. The soils determined the existence of resorts of superior and medium quality. In some situations, as productivity limiting factors appear: the deficiency in useful mineral substances, the active acidity of the soil, the shortage of accessible water, the low temperatures in and around the soil, etc. Particularly important are the destabilizing factors that affect the trees as well as the limiting ones. In the vast majority of the territorial area under study, the natural regeneration of the main forest species in the area is done well and very well. In the studied territory are the forest species characteristic of the phytoclimatic floors in which it is located. The predominant oaks are found in the plain and low hills, on soils of the luvisol class, they are better adapted to these heavier seasonal conditions determined by the presence of relatively compact (high clay content) soils and poor rainfall regime. In the higher meadow areas the oak, ash and lime tree vegetate. First, some data was presented regarding the location of the territory, the study of the forest site, the methods of work. All these used as base the data from the forest management plans of the two forest districts.
