Utilisation of brick recycled materials for water retention in soils
Šmírová, Barbora ; Palovčík, Jakub (referee) ; Opravil, Tomáš (advisor)
This bachelor´s thesis deals with possible utilizations of brick recyclate as an element which cooperates in the field of water retention in the landscape, especially in agricultural soils. Brick recyclate has the same composition and properties as a classic burnt brick, and therefore is very wettable and porous. Above all, these properties are the key element to using brick recyclate as a water holding element in the soil. The aim of this thesis was to determine the ability of brick recyclate to retain water in the soil and then release it back into the soil. Various fractions of brick recyclate were tested experimentally. First experiments were performed with fine quartz sand, and then with two different real samples of soils.. The time for the evaporation of all the added water from the test mixture was assessed. For real samples of soils, experiments continued on the plants under defined laboratory conditions.

Truck-gardening in system of ecological agriculture
JURÁKOVÁ, Andrea
In the organic farming system is farmed more consistent with nature. Careful handling with the environment, biodiversity, quality care of the soil, preference of renewable resources and recycling of materials are supported. This agricultural system is able to produce high quality food. This bachelor thesis is a literary review. Its aim is to show the different principles in the cultivation of vegetables in organic agriculture. The first part of this thesis is focused on organic farming and it includes the definition of basic concepts, description of the targets and principles of organic farming and its development in the Czech Republic, the European Union and the world. The second part of this thesis contains basic information, which relate to the principle of growing vegetables, their protection, quality control, certification, labeling and storage of vegetables in the organic farming system.
