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.

In a pursuance of a small-scale field experiment was to monitor the impact of extrarooted nutrition as one of the factors which influence the yield and technological quality of sugar beet. In the course of the vegetation was monitored for the growth and development of diabetes and the dynamics of change of its quality. On the basis of the observed results were evaluated by the following parameters - yield bulev, the yield shaw, sugar content, soluble ash, alpha-amino-nitrogen and MB factor. The highest yield of root was recorded after the application of fertilizers Yara Vita Bortrac (127 t/ha). At the time of harvest was the highest yield shaw determined after the application of the product Carbonbor On (39,6 t/ha). The highest sugar content was determined in the two years after the fertilization of the product Carbonbor. In the average of the two years has moved the content of soluble ash in the range of 0,68 - 0,75 %. The lowest was at the variants with the application of Yara Vita Brassitrel and highest in the variant, after the application of fertilizers Carbonbor K. The content of alpha-amino-nitrogen in different years differed, in the year 2012 amounted to the average of the value of 36,7 mg.100 g-1, and in 2013 was 26.3 mg.100 g-1. The highest value of the MB factor was determined for the variants with the application of fertilizers 3 Carbonbor K. Also there has been achieved a favorable value of 27. Most mature sugar beet has been harvested after the application of fertilizers Carbonbor.
