Potential of biomass resources in CZE and costs of its energy utilisation - II
Štěrba, Martin ; Pavlas, Martin (referee) ; Máša, Vítězslav (advisor)
In recent years, we are more and more confronted with the concepts of bio-energy, biomass or biofuels. In conjunction with the increasing pressure on the use of these commodities thein demand is increased. Crops for the purpose of energy production may be an important renewable source of energy and are the primary topic of the work submitted. Introductory chapter provides distribution, characteristics, list of representatives of crops and ways of energy utilisation the crops. Is folloved by an introduction to the legislation dealing with energy crops. The market for biofuels is still in its infancy, and therefore the work submitted presents only general view of the current status of the production and use in the Czech Republic and potential prospects. Interesting is also the position of farmers and the issue of competitiveness. These areas are collectively analyzed in the final chapters.

Fast-growing trees as a renewable energy source
Žvaková, Veronika ; Půčková, Helena (referee) ; Kotlík, Josef (advisor)
This bachelor thesis is focused on biomass as a renewable energy sources. The main topic is fast growing trees and their effects on biological diversity, the local ecosystem and landscape ecology. Literature survey was conducted regarding using this kind of biomass in the Czech Republic. Thesis reviews technological methods of cultivation and treatment of fast growing trees.

Ekonomický přínos pěstování japonských topolů pro rodinný rozpočet
Umlášková, Pavla
This bachelor thesis deals with the issue of Japanese poplar as a representative of fast growing species. The first part describes characteristics of the clones grown in our region and production in the world as well as in the Czech Republic. In the second part is elaborated the technology of production from selection of land to its destruction. The following part contains evaluation of recorded costs of wood production and estimation of future expenses that have not yet been paid for. The thesis includes also estimation of the plantation yield and suggested variants of house heating with using the results obtained. In the final part there are mentioned methods for use of harvested wood mass.

Hodnocení vlivu prostředí na produkční parametry plantáží rychle rostoucích dřevin
Šťastný, Hubert
This thesis deals with the cultivation of fast growing trees, mainly the Japanese poplar, as the most widespread species cultivated in our territory. The first part of the thesis describes the history of fast growing timbers, followed by presentation of individual species of poplars. Furthermore, the individual methods of cultivation technologies are analyzed, from the selection of suitable habitat to the final reclamation of the plantation. The final part of the literary review describes the non-production functions of plantations, including possible negative impacts of growing fast growing timbers. The practical part of the thesis describes a private plantation of Japanese poplar clones located in the cadastral area of Žabčice. The measurements were made on a particular plantation. From the obtained data an estimate of the future plantation yield for individual clones was performed by power regression. The final part of the thesis discusses the data obtained mainly from the economic point of view.

Vybrané ekonomické aspekty pěstování rychle rostoucích dřevin
Smílková, Aneta
My bachelor thesis deals with the issue of growing fast-growing trees. At the beginning of the work there are suitable trees and possible ways of their cultivation. The work continues by focusing on sprouts plantation. All agrotechnical interventions are described here, from foundation to disposal, and the use of harvested wood. The work also outlines energy parameters, production parameters and yield potential. The work is focused especially on the economics of cultivation with the indication of the costs of individual agrotechnical interventions during the existence of the plantation. In the final part of my bachelor thesis I presented a model example for sprouts plantations of fast-growing trees. From an economic point of view, possible ways of harvest are compared.

Rychle rostoucí dřeviny - ekonomické srovnání výmladkových a množitelských plantáží
Kovářová, Kateřina
This bachelor thesis is aimed to economic comparison of short rotation coppice and propagation plantations. In the first part of thesis is description of main kinds of fast growing trees suitable for growing on plantations. The second part is aimed to describe the way of growing from the esta-blishing care and liquidation of plantation. The model plantations are chosen according to staple product of coppice plantation cultivated for production of wood chips or fire-wood, and the propagation plantation. Use of wood mass from fast growing trees is influenced of the way of growing plantation. Thesis is mainly focused on economic comparation of model plantation. For particular types of plantation, economic return is evaluated in order to find out which kind of plantation is for planter more profitable. As a result of this bachelor thesis is recommendation for plantation choice, based on exter-nal market conditions.

Technologie pěstování rychle rostoucích dřevin
Vodák, Matěj
This bachelor thesis focuses on the cultivated types of short rotation coppice and the mechanisation used for their cultivation. The work describes in detail the species of poplar and willow that are located in the Czech Republic and around the world. The work also briefly mentions the clones of this short rotation coppice that are cultivated exclusively for energetic purposes. The second part describes the way of growing short rotation coppice and the technology used starting with the preparation of the soil for plantations and ending with the liquidation itself. The technical instruments and procedures used in the individual phases of the plantation are closely described. The third part of the work is the attempt (experiment) to build a group of mobile energetic instruments and use them together with the technical instruments on the plantations of the short rotation coppice.

Procházka, Vít
This bachelor thesis deals with the issue of fast-growing wood plantations with particular focus on Japanese poplars grown in the Czech Republic. The first part of the thesis presents an overview of various tree species that can be grown in the Czech Republic. It also includes factors influencing new emergence and growth of these plantations. The following section describes ways of growing these woods, or choosing suitable places for their planting. The second part of the thesis is devoted to productive, energetic, or economic (yield) parameters of these fast-growing woods. The last part of the thesis focuses on influential factors of plantations in specific areas.
