Uplatnění meziplodin jako stabilizujícího prvku v protierozní ochraně v oblasti podhůří Šumavy / The application of the intercrop as a stabilizing element in the erosion control in the area of the foothills of Sumava.ŠLAPÁKOVÁ, Veronika January 2015 (has links)
The aim of this thesis is to evaluate the possibility of applying the intercrop in the erosion control crop rotation and their effect on the system of the sustainable agriculture and assess the suitability of utalizition of the intercrop as an element of the erosion control for the environmentally friendly farming on the arable ground. Erosion phenomena will be evaluated in the selected location and in the cadastral Borovany. The outcome will be the evaluation of the washes of the conventional crop rotation and of the process which uses the intercrop using the USLE method.

Protierozní ochrana svahů za využití vybraných geosyntetikPilařová, Pavla January 2014 (has links)
Perpetual development of mankind inevitably goes hand in hand with growing number of construction projects, mining and recultivation activities. Erosion control of newly established hillslopes and constructions is therefore essential. The thesis is focused on theoretical characterization of soil erosion and its impact on soil degradation, water management and potency of material damage. Furthermore the thesis describes the role of vegetation and erosion control products (both natural and synthetic) which are used for erosion protection of hillslopes. The main aim of the thesis is to deepen the expert data in the area of usage of permanent geomats (GMA) and their collaboration with grass cover in the range of erosion protection of hillslopes. The thesis includes laboratory and field experiments. The grass roots parameters (length, surface area, diameter, volume) were measured during the laboratory experiment and collected data were used for statistical analysis. The results of the laboratory experiment led to the acceptance of the hypothesis, that the presence of selected GMA in the soil profile does not have any impact on the growth and development of the root system of selected grass species (at a level of significance of alfa = 0,05). Four types of erosion control systems (ECS) were used for the field experiment plots (three ECS with GMA and one ECS without GMA). Soil erosion rates from each ECS were statisticaly compared. The results of the field experiments indicate, that the installation of the GMA into the soil profile does not improve the erosion control effect as expected and the main agent in the erosion control of newly established experimental plots was developing erosion control grass mixture.

Porovnání PK a KN držby pozemků a posouzení erozního ohrožení při postupném zvětšování ploch orné půdyKOVÁŘOVÁ, Kristýna January 2016 (has links)
The aim of this work is to clarificate water erosion issues, which were compared by study and analysis of history in a selected area. In the literature review of this study, evolution of agriculture based on land and political ownerships is described. The next things explained in this study are erosion, its causes, repercussions and ways how to fight erossion. The chosen area was cadastral territory Bavorovice. There were used historical maps from years 1827 and 1972, which were landed by cadastral workspace in České Budějovice. For the analysis, historical maps from years 1827 and 1972 were provided by cadastral office in České Budějovice. The maps were compared with a current state after finished KoPÚ. In those maps as well as in the actual cadastral map a few land fields were selected for calculation of average soil loss per year in solved time periods. For the calculation, (of average soil loss) universal equation for average soil loss from land by Wishmaier and Smith was used, which is used. This equation is used for KoPÚ projects as well. The results were evaluated and compared in conclusion of this study.

Vyhodnocení změny mikrotopografie svahu a půdního profilu v závislosti na zpracování půdy různými technologiemi / Assessment of changes in slope topography and soil depth redistribution in relation to different soil tillage technologiesUreš, Jan January 2016 (has links)
Water, wind, or tillage-induced soil erosion can significantly degrade soil quality and decrease crop yield from farm fields. Traditionally, the research in soil erosion is mostly focused on water or wind erosion. Recent studies over last two decades, however, point to the importance of tillage operations as a source of soil translocation on hilly agricultural land. Tillage disturbs the soil not only vertically but also horizontally by throwing soil in the tillage direction.
This study was designed to assess the soil translocation effect in topsoil before and after 5 tillage operations by using three different practices, namely mouldboard ploughing (A), chisel plough (B), and disc harrow (C) in the Chernozems region at the Sardice (South Moravia, the Czech Republic).
The influence of different tillage practices on the changes in depth of topsoil was assessed through description of 37 shallow pits - 10 pits was digged out before the tillage operations and then other 27 pits after five tillage operations. The results of the soil survey are based on the evaluation of the stratigraphy of the soil profile where the potential loss of topsoil was determined by a change in transition between the dark Ac horizon and yellow loess Ck horizon and by the type of the transition. Shift of topsoil after five performed operations is in the range of 9-15 cm at the top position of concave-convex slope and 4-14 cm at the top of concave slope. From the results of the experiment are also apparent significant shifts across to each tillage practice (C to A), which are, however, more or less caused by the shape of the slope.
By creating and comparing the DEM for the conducted experiment I managed to learn that the largest transport of soil particles was caused by mouldboard plough. Transport of soil particles was larger in the vertical direction than in the horizontal and moved in the range
of -5 to +13 cm. When undermining by a chisel plough was a significant horizontal shift of soil particles to the sides in the range of -5 to +5 cm. The method of shallow tillage with a disc harrow showed a change of the relief in the horizontal direction also in the range of -5 to +5 cm.

Optimální digitální model terénu pro erozní analýzy / Optimal digital terrain model for erosion analysisStředová, Kamila January 2017 (has links)
The thesis deals with the question of using available sources of elevation data for the evaluation of topographic factor in estimating the amount of water erosion in the area. Work compares the results with consideration to the origin of the data, the accuracy and resolution of the digital terrain model, which is interpolated from the source data. The calculation of topographic factor in ArcGIS will be confronted with the results of the Universal Soil Loss Equation (USLE). The frequency of compliance will tell us which data source and digital terrain model resolution is the most suitable for determining the topographic factor.

Analýza výskytu vysokých koncentrací celkového fosforu v malých zemědělských subpovodích / Analysis of high concentrations of total phosphorus incidence in small agricultural subcatchmentsDUŠEK, Jiří January 2017 (has links)
This thesis focuses on analysis of the peak values of phosphorus concentration in small agriculturally used subcatchments. The cycle of phosphorus in nature, in water and issue of the eutrophication is described in this thesis as well as basic characteristics of three monitored subcatchments. The concentration of phosphorus, flow rate and precipitation was measured in these three monitored subcatchments. Peak values of phosphorus concentration and possible impact of rainfall-runoff occurrences on these peak values are as well analyzed in this thesis. This research uses statistical methods. The final part of this thesis assesses the impact of rainfall-runoff occurrences on the peak values of phosphorus concentration. Other possible factors which could cause these peak values are also discussed.
