Abstract
Being part of the Pre-Carpathian Region, Pre-Gorganian Carpathians are situated between the Svicha River in the northwest and the Lychka River in the southeast. Taking into account the analysis of soil maps, the computer program ArcGis 10,0 and own field researches were determined the areas of the main types of soils within the studied territory and the indicators of their agricultural usage. The agricultural usage of the lands of the Pre-Gorganian Pre-Carpathian Region is 47,5%, and the plowing of agricultural lands is 53,8 %. Under perennial plantations, hayfields and pastures were occupied 1,4 %, 3,4 %, and 11,2 % of agricultural territories. The distribution of soils within the Pre-Gorganian Pre-Carpathian Region is due to high altitude zonation. The change in absolute and relative heights from the Dniester River to the Carpathians is the dominant factor that determines the distribution of soils. Alterations of the hypsometric levels define the parameters of climate changes, the level of groundwater occurrence and types of plant formations, which together determine the morphological features and physical and chemical properties of the soils of the Pre-Gorganian Pre-Carpathian Region. The floodplain of the Dniester, Prut and their tributaries are alluvial-ray, alluvial and peat soils. On the first and second terraces are turf gley, meadow, meadow marsh, turf podzolized soils. The third and fourth terraces are covered with turf-podzolic surface-gleyed soils, which are background in the Prehistory of the Pre-Carpathian Region. In the fifth and sixth terraces, brown-ground-podzolic and sod-brown soils are common. The surface of the seventh terrace is occupied by brown mountain-forest soils, which are background for the mountains of the Carpathians.
