Vliv vápnění a způsobu sklizně travních porostů na fyzikální a hydrofyzikální vlastnosti pseudogleje
Mikulenčák, Štěpán
This thesis evaluates impacts of liming, mulching and mowing grassland on soil physical and hydrophysical properties, in my case from pseudogley, which was at the site of experiment. There were used a soil samples for the analysis which were got from experiment site in years 2013, 2015 and 2016 everytime in October in depth 5-10 cm. There were analyzed the broken soil samples and these attributes were determined: organic carbon, active acidity and exchange acidity. From compact soil samples were determined different attributes, such as dry bulk density, total porosity, volume non-capillary porosity, water holding capacity, moisture and minimal air capacity. The results of the analyses were statistical evaluated and evaluation did not determine conclusive effect of liming treatment (1,8 t.ha-1 CaO) on most of the observed soil properties. Otherwise, mulching influenced most of the attributes in the positive way. Compare to mowing, the biggest inconvenience caused only the pH decreasing.

Péče o travní porosty v rámci soustavy Natura 2000
Výletová, Lenka
Bachelor thesis was conceived in its first part as a general literature review describing history, significance and characteristic of grasslands within the system Natura 2000. Not only pastures are considered as a grassland, but also continuous vegetation with domination of grasses intended for feeding purposes and technical use, which perform production and non-production function. Grazing cattle is an essential element of protected areas. In a second part of the thesis I focuses on Natura 2000, its origin, directives and goals description. In separate chapters is mentioned the care of grasslands within the system Natura 2000 and description and destruction methods of invasive species. The third part is about selected Sites of Community Importance in Hodonín district. I chose and described five sites into Natura 2000 system around my home. These sites are described geologically, pedologically and botanically. I focused on a significant and vulnerable species in this areas. I focused on the recommended care for selected areas in the last part.

Typological classification and categorization og grasslands in selected area and recommendation of sutable grassland management
KADLECOVÁ, Jana
The aim of this thesis was to create the botanic snap of the chosen locations, which were meadows, grasslands, pastures and also fallow grass areas, to determine the area coverage of three main agrobotanic species i.e. grass, herbs and clover, to process it with the statistcal software and determine the method and intensity of use and fertilization of individual locations and suggest the suitable prato-technical methods. The cenological structure of the locations has been observed and described using botanic snaps. The prato-technic method used were documented for each of the locations and evaluated the influence on the cenological structure. The research was performed in locations Vřeskovice, Čeletice, Městiště in the region Pilsen, former district of Klatovy. In each location the botanic snaps were taken from 3 areas of about 5 x 6 meters each. There were determined the area coverage of grass, herbs and clovers and calculated the mean indication value of humidity. Mean indication value of humidity is the parameter usable for determination of permanent grassland management and utilization. The data from the research was elaborated in software MS Excel. I recommend to manage the analyzed permanent grasslands as follows: 1. The meadow Vřeskovice behind the sewage cleaning station - additional sow of perennial rye grass, meadow clover and white clover. 2. The meadow Mstice - total recovery alternatively conservative prato-technic measures - manure fertilization for about 20t/ha and additional sow of meadow and white clover and grass - red fescue, blue grass and perennial ryegrass. 3. The meadow above the transformer station Vřeskovice - keep on current management od additional clovers sow. 4. The pasture Čeletice grazed by horses - keep on current management or additional sow of red fescue, tall fescue and timothy grass. 5. The meadow Městiště with combined utilization by cattle pasture and mowing - keep on current way of use. 6. The pasture Vřeskovice grazed by cattle - keep on current utilization or additional sow meadow and white clover. 7. The pasture Vřeskovice grazed by sheep - keep on the current utilization, in future after the reduction of dangerous knapweed to decrease the amount of pastured animals. 8. The fallow meadow Vřeskovice behind Petrovický neither mowed nor pastured - proposed mulching twice a year for about 1 or 2 years, then pasture or pasture of extensive cattle breed (Galloway) or sheep or periodical mowing once or twice a year. 9. The fallow meadow Vřeskovice trench at the farmhouse - leave as a fallow meadow improves the biodivesity, optionally to mow once or twice a year from estetical reasons.

The influence of pratotechnical way of use on species composition and characteristics of selected permanent grasslands
HAŠKOVCOVÁ, Petra
The aim of this work is to assess the influence of mowing and grazing with different frequency and fertilization on species composition, fodder value and bimas production. The experiment was carried out at the village of Hrazany, district of Písek in 2017. The ecological conditions of grasslands, terms and intensity of use, biomass production, botanical composition and species diversity were monitored on these parcels. The data obtained was used to calculate the Hill's Diversity Index, calculate the pasture load, and calculate the yield in dry matter. Non-fertilized plots reach the lowest yields. Most grasses are located on the soil fertilized with urine. The smallest disturbance and shortcomings appear on the pasture with the finch pasture. The values were statistically processed.

Dopad caespestechniky na kvalitu užitkových trávníků
Říha, Tomáš
Utility lawns are lawns that complete the human environment and that is why they need proper care. The objective of this study was to characterized the utility lawns and lawn care. Among the basic caespetechnique measures belong cutting, verticutting, aeration and fertilization. The lawn is necessary to cut as often that maximum 1/3 of the assimilation area would be removed. Verticutting removes lawn thatch of vegetation that prevents the access of water, air and nutrients to the root system. Pruning of the lawn is sufficient twice a year to a depth of 1.5 - 2 mm. Aeration aerates compacted vegetation substrate to a depth of 50 - 150 mm. For sandblasting is used a sharp silicious sand but it is also possible to use new materials such as a crumb rubber. It is necessary to divide the dose of fertilization into several terms to ensure the functionality of the lawn across whole vegetation season. Nitrogen fertilization encourages lawn density by having better offshoots of grasses. The plant tissues are stronger by supplying the required amounts of phosphorus and potassium and it also increases resistance to drought, cold temperatures and fungal diseases.

Monitoring of rolling greens methods and frequency impact on green speed on selected courses
Fichtl, Lukáš ; Kumhála, František (advisor) ; Chyba, Jan (referee)
This diploma thesis is focused on monitoring of golf green rolling methods and its frequency impact on green speed on selected courses. In the first part of this thesis issues relating to golf, global history of golf and history of golf in Czech Republic are analyzed, also are described golf green construction methods here. There is also described golf green rolling and the effects of rolling. The next part presents methodology of experiments and presents the results of these experiments. The analyzed data showed that the green speed did not decrease too much during the day. The results of another experiment showed that the different types of used rollers have just a little effect on a final green speed increase. In other words, the differences in green speed increasimg, caused by using of different green rollers, cannot be detected by any golf player.
