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.

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 Tool for Preventing the Impacts of Climate Change
Humešová, Tereza ; Syrovátka, Oldřich (advisor) ; Weger, Jan (referee)
This work was created as a response to the drought in the summer of 2015, which revealed the risks associated with a lack of moisture in the soil due to inadequate management landscape. The main objective is to select areas in the chosen territory where it would be desirable to implement measures that would lead to stabilization of drainage conditions, and support the landscape and territorial system of ecological stability (biodiversity).In addition to creating the appropriate landscape features and the introduction of environmentally friendly agricultural crops eligible planting fast-growing trees (FGT), which on agricultural land, for the interest of stabilizing of drainage conditions, in many ways irreplaceable alternate functions of the forest.This culture is therefore paid special attention; Work has focused on the estimation of the possible production of wood and possibility of its eventual use.The study is prepared as a possible basis for practical solutions to complex land arrangements in the cadastral areas. It was found that the FGT would be advisable to cultivate an area of up to 2461 ha.
The influence of genotype , habitats and agricultural technologies for producing energy wood phytomass selected
CHRT, Vladimír
This diploma thesis deals with the cultivation of fast-growing wood and concentrates on the influence of particular factors like e.g. location, agrotechnology and fertilizers, which have a crucial impact on the phytomass production. Moreover, the thesis evaluates the economic efficiency of this type of sustainable energy ressource, which can be a source of local business. Introductory theoretical chapters describe essentials rules of the cultivation of fast-growing wood. Furthermore the thesis presents general information in this field and proposes suitable wood clones. In addition, the thesis outlines the process of choice and preparation of the agricultural parcel, the usage of various fertilizes, herbicides and agrotechnology. The applied core characterises the business case itself. The primary research compares financial investment and its return of two examined agricultural parcels under the prerequisit of suitable choice of location and agrotechnology. A trail phase depictes the cultivation of fast-gworing wood and discuss presumptions for succesfull business. This thesis is mainly based on primary research. The acquired data are further analyzed and the final chapter attempts to outline the results and suggest measures.
Attitudes Management of large Farms to Produce fast-growing trees
Zelenková, Aneta ; Syrovátka, Oldřich (advisor) ; Duchek, Stanislav (referee)
The aim of this thesis was to ascertain the attitudes of management of selected large farms operating in the South Region in the production of fast-growing trees on-the-agricultural land and attitudes to the concept of greening. To fulfill the goals of this thesis were used questionnaires - a structured questionnaire sent by e-mail after prior phone contact. The research covered 18% of cultivated agricultural land throughout the South Region. They were classified according to the jurisdiction of the district. It was found overwhelming preponderance of negative attitudes towards the production of SRC and reasons for this opinion. Production is dedicated to one of the thirty producers. The concept of greening is considered inconsistent. Positive attitude toward greening occupy a particularly company with combined agricultural production, negative attitude then producers od crop production.
Studies resources for local heating in Sezimovo Ústí
Ledvinková, Markéta ; Syrovátka, Oldřich (advisor) ; Vetýšková, Lenka (referee)
The theme of bachelor's thesis is " The study of resources for local heating in Sezimovo Ústí." The target of thesis is determinate the present structure of heat sources which are used by inhabitants in the city of Sezimovo Ústí, citizens satisfaction with local heating and air situation which occur with each winter season.

Vyhodnocení plantáže RRD založené na zemědělské půdě v majetku Lesů města Brna, a.s.
Stuchlý, Ondřej
The work deals with the analysis of production and economic parameters of plantation short rotation coppice LMB in LS Deblín. Production plantation was assessed after 7 and 8 years since its inception through a network of inventory plots and stencil poplar. Surveys to be wood volume (m3) and the total biomass (o.d.t). Plantation economy was measured as the difference between revenues and costs. The survey was also regenerative experiment to assess the influence of the width of the cuts on the growth of poplar saplings. Total volume production of tree plantations for 2012 was set at 46,95 +/-9,7 m3. Total volume production of tree plantations for 2013 was set at 63,41 m3 +/-10,5 m3. Total dry weight biomass for 2012 amounted to 23,31 t/ha ie 3,33 t/ha/year. The following year, the total biomass dry weight was for 8,42 t/ha greater. The average production was also greater, it reached 3,97 o.d.t/ha/year. The total cost of the plantation in the first rotation reached 79 022 CZK. The cost of timber harvesting in 2012 amounted to 7 485 CZK. The total yield of the plantation in 2012 was 72 906 CZK. The profit in 2012 amounted to -6 116 CZK . Total revenue for 2013 amounted to 99 249 CZK. The profit in 2013 amounted to 20 227 CZK. Next experiment shows vigorous sprouting capacity. Wider cuts (3 lines) is generally larger than the cuts closer (2 lines). It was also found that the wider lines is greater proportion of sprouts in the greatest height class (+2 m).
Effective use of phytomass in the protected area of the National Park Podyjí
FORMANOVÁ, Petra
The objective of the thesis is to evaluate the possibility of the effective use of waste and phytomass specifically grown for energy purposes in the protected area of National Park Podyjí. The task was to characterize the source of phytomass in this environmentally sensitive area. The data were collected by studying documents, visits to enterprises and institutions, and personal consultations with business and other stakeholders. The result of this work is a brief assessment of the production potential and the factors influencing its development. Due to the nature of the territory, to suggest measures for efficient use of land for the production of energy phytomass with regard to the attitudes of farmers and the authority of nature and landscape.
