Application of intercropping as a stabilizing element against erosion washes away
KUKAČKA, Vladislav
The thesis was focused on the application of theorethical knowledge about catch crops and their influence on water erosion in practice. Its task is to evaluate the effect of the inclusion of catch crops in crop rotation in light of occurance and extent of water erosion on the example of agricultural enterprise ZEPHYR Františkovy Lázně, s.r.o. The task is also assessment of the possible combinations of crops and catch crops and suggestion for their use in middlegrowth period. The universal equation for calculation of erosion wash by Wischmeier and Smith was used to evaluate and calculate an erosion parameters for a given locality. The result of this thesis is reduction of soil loss by 26 % on lands with catch crop usage as a stabilizing element, compared to the classic conservative rotation of crops.

Solution of soil protection from erosion in model catchment - Zvíkovský stream
ŘEHOUT, Jan
The theme of my graduation theses is a solution of the soil protection from erosion on the model catchment of the Zvíkovský stream. The aim of this work is canvass of the catchment Zvíkovský stream in the view of the pedology, hydrogeology, climatology and calculate the soil loss from the areas in consequence of the water erosion. I used the equation losses of the soils from the area according Wischmeier and Smith and the assesment of the transporting the sediment runoff according Williams and Berndt which was calculated with the help of the programme ERCN {--} the enumerations required for the suggestion of the precautions from erosion. The map basis of this work is the basic map of the Czech republic 1: 10 000 and the water utilization map of the Czech republic 1:50 000.

An Impact of Erosion on Soil Quality
HOSNEDL, Pavel
Nowadays, erosion is a global problem. This thesis is aimed at studiing the impact of erosion on the soil quality, especially at humus content in soil. Humus content and humus quality is usually used as a criterion for assessing a soil quality. The proposal of methodology for monitoring of humus content change in time and dependence of its content on land management and steepness of slope is a part of the thesis. This thesis is written as a literary summary of studies which have been done so far.
