Hodnocení erodibility vybraných hlavních půdních jednotek (BPEJ) s využitím ke specifikaci faktoru erodovatelnosti v rámci RUSLE

The soil erosion is one of the most important factor which brings about modification of landscape. Presently, there is more than half of the agricultural land resources endangered in the Czech Republic, in particular by the water erosion. The aim of this thesis is to evaluate susceptibility of selected soil units to the water erosion by force of erodibility factor (K-factor) which is one of the input parameter of Revised Universal Soil Loss Equation (RUSLE). Seven types of soil appearing at agricultural land at the South surroundings of town Brno were selected for the pedological exploration and following determining of the K-factor. On the basis of K-factor figures a map depicting variability of the area from view diversity of susceptibility to the water erosion was made. Soil slaking is closely connected to the soil erosion which characterize the soil from the view of crumbling of soil aggregates and inlay of the soil surface. The susceptibility of the selected soil types to destruction of the soil structure was assessed in this thesis. Further, the task of comparison between present attributes of the soil and the data of Complex exploration agricultural land, which were the base of evaluating dynamic of the development of soil environment, is dealt
