The biomass production for enegetic use from permanent grasslands and influence of ferment fertilisation on permanent grasslands
HAŠKOVCOVÁ, Michaela
Permanent grassland in agricultural landscapes represents an important position in terms of biodiversity. Becoming a habitat of endangered plant species, they are rich in flowering plants and also provide wintering territories to many animals. The aim of this study is to assess the biomass production of grassland for energy recovery, describe ways to use herbaceous biomass and impact of digestate on species composition and productivity of grassland. The experiment was conducted on the land in the village Dmýštice, located in the county of Písek. The site of fertilization by digestate is located near the village of Novosedly, county Strakonice. On these lands there were monitored ecological conditions of grasslands, dates and intensity of their use, botanical composition, species diversity and biomass production. Furthermore, this thesis uses methods of preservation of harvested biomass and comparing fertilized and unfertilized plots. The obtained data were used to calculate the Simpson index species diversity, nutrient and water mode positions. The values were statistically processed.

The influence of ecological conditions on permanent grassland and optimalisation of pratotechnic practises in Borkovice area
DUŠÁK, Radim
This dissertation thesis researches the impact of ecological conditions on the permanent graminaceous cover not faraway from the peatland in the Borkovice region. These ecological conditions primarily mean water regime of the habitat. The nutritive regime and the fodder crop value are monitored in this thesis. These data were acquired with the help of the vegetation composition, using bio-indikative methods. Resulting values are described in the thesis, and their mutual relations are also stated there. In accordance to the ascertained results, proper pratotechnic measures were proposed. These measures try to harmonize the productive and non-productive functions.

The frost susceptibility of the soils and materials to subgrade of the pavements
Mašek, Jakub ; Zajíček, Jan (referee) ; Stehlík, Dušan (advisor)
This diploma thesis deals with the issue of the determination of the frost susceptibility of soils in the subgrades of road structures. The theoretical part compares the ways of testing the frost susceptibility in the Czech Republic and other selected countries of the European Union. Furthermore, it also deals with the development of the frost susceptibility index in the Czech Republic. The empirical part focuses on the laboratory testing of the frost susceptibility of the given sample of soil by the direct frost heave method. Moreover, it also deals with the simulation of penetration of frost by the subgrade and the possibility of shortening the length of the freezing during the direct testing the frost susceptibility.

VUMOP - 1501
Fabiánek, Tomáš ; Pivovarník, Marek ; Hanuš, Jan
The object of the hyperspectral campaign VUMOP 1501 was the application of remote sensing to research of soil erosion in agricultural. During scanning was used whole spectral range of FLIS – Flying Laboratory of Imaging Spectroscopy. Selection of locality and term for aircraft scanning was established according of subsequent application.

Polkovice 2015
Hanuš, Jan ; Fabiánek, Tomáš ; Pivovarník, Marek
The object of the hyperspectral campaign Polkovice 2015 was the aplication of remote sensing to research of water regime in agricultural crops. Selection of locality and term for aircraft scanning was established according of phenological phases and selected species of crops.

VUMOP – 1504
Fabiánek, Tomáš ; Pivovarník, Marek ; Hanuš, Jan
The object of the hyperspectral campaign VUMOP 1504 was collect a new data from areas with significant affection of soil erosion and verified of the methods from campaign VUMOP 2015. During scanning was used whole spectral range of FLIS – Flying Laboratory of Imaging Spectroscopy. Selection of locality and term for aircraft scanning was established according of phenological phases and selected species of crops.

Concept of the revitalization of Nature Reserve Kapličky peat bog and continual monitoring of water regime and vegetation
PAVELCOVÁ, Lenka
The "Rašeliniště Kapličky" Nature Reserve is situated in the eastern part of the Šumava Mts. The reserve contains different peatland vegetation types - ombrogenous and transition bog parts. The area was partly drained due to extensive mining, pasturing and forestry in the past There are variously old drainage canals now. My thesis contains (i) the evaluation of groundwater table fluctuation and its relationship to vegetation composition and the drainage intensity and (ii) the evaluation of plant species composition in differently drained parts of the peatbog. There was strong relationship between actual groundwater table and precipitation, especially in drained areas, the diversity and the occurrence of expansive species were also related to groundwater table. A map of dranaige network inside the peatbog (1 : 3 500) and vegetation map (1 : 4 000) in the ArcMap programme for GIS environment were constructed. In the most drained part of the area the revitalisation measure was proposed {--} installation of wooden dams for blocking of drainage system.
