Following research in 1995-1999, soil map in the scale 1 : 10 000 was produced. The aim of research was to specify soil structure of the Belianske Tatry Mts, as well as to study soil interactions with substrate, relief, plant communities and influence of man. The most significant factor effecting soil structure are calcareous and silicate-calcareous rocks. They caused formation of Rendzic Leptosols and Calcaric Cambisols in 43% of area and eliminated vertical soil zonation. The least various soil condition were in northwestern, northern and southwestern parts of the mountains, where Cambisols prevail, which are the most extended soils in Belianske Tatry Mts (about 33.5%). The relief affects soil properties by decline, locality and geometrical forms. Shallow soils can be found in the terminal sites, on the steep slopes and on the convex relief forms. The soils of middle slope parts and concave forms are deeper (to 0.6 m), whereas down slope parts and foots have deep soils with lower skeleton content. The climate and vegetation affect soil structure especially by decarbonization of the surface layer, so despite of calcareous rocks, some more acid soil may be formed. Although 57% of investigated soils have origin in calcareous, or calcareous-silicate parent rock, only 36% of soils have neutral reaction. Anthropogeneous influence can be seen also in exceeded bulk of arsenic (As) and cadmium (Cd). The tourism causes especially water erosion, which less deep and humic soils are subduing to. Shallow and stony soils with low content of fine earth are rather immune
