Remarks on plants indicating soil characteristics

Abstract

Soil formation is a process of biological nature, because humus, the specific and fundamental soil component, is organic. Soil mapping required the knowledge of soil classification, climate, rock relief and plant species from canopy, which determined the soil formation and evolution. The flower habitat is the most important element from the point of view of soil mapping, because it allows getting practical and synthesis deductions of zonal, interzonal and azonal soil distribution. Frequently, in soil mapping, they specify only the genus of dominant plants (for instance, Festuca sp.and Carex sp.), without the species. For the classification of plants from the spontaneous flora, it is necessary to specify both the species of plants found in the studied habitat and their abundance and dominance. The paper presents only a few plant species belonging to the same genus, which developed on certain soil types with different characteristics.
