Design of the manure spreader
Pacher, Ján ; Molva, Martin (referee) ; Kašpárek, Jaroslav (advisor)
The diploma thesis deals with the structural design of a solid manure spreader and the subsequent strength control of self-supporting construction. The introduction of the work consists of a research analysis of current design solutions of spreaders on the market with similar parameters as in the assignment. Subsequent chapters deal with the conceptual design of the spreader, preparation of the calculation model, suitable replacement of the components and evaluation of the strength analysis itself. The diploma thesis is accompanied by partial drawing documentation. The work was created in cooperation with ZDT Nové Veselí.

Dozer of non-homogeneous materials
Henzl, Lukáš ; Hloska, Jiří (referee) ; Malášek, Jiří (advisor)
This thesis describes the design of the hydraulic dozer of inhomogeneous materials, especially for ploughing of manure from the stables of corridors, with the possibility of dozer changes in working widths as needed. This machine will be attached to the telescopic handler Manitou MLT 845 – 120 LSU. Another part of the thesis is the technical report about similar machinery and the justification of designed concept of the pusher block. The thesis presents important technical calculations and an overview of possible inhomogeneous materials that could be ploughed by the plow blade. The thesis includes drawings of weldment of the centre of blade and drawing of the whole composition of plow blade.

Vliv aplikace různých hnojiv na vybrané půdní vlastnosti
Navrkal, Stanislav
The diploma thesis is focused on monitoring the influence of the application of different fertilizers depending on the vegetation cover on selected physical, physico-chemical and chemical properties of the soil. The experiment took place on the site of the Forage Research Station in Vatín. The experiment was based on a combination of mineral fertilizer, digestate, manure and vegetation covers, permanent grass cover, sowing procedure, monoculture of corn. From each variant in the years 2018, 2020 and 2022, undisturbed samples were taken from a depth of 15 cm to determine the reduced volumetric weight, porosity, maximum capillary capacity, minimum air capacity and disturbed samples up to 30 cm from which the soil reacts and the content of accessible nutrients for plants were determined soil. On the basis of determined values and their trends were found that the digestate does not have any negative effects on soil properties. Nevertheless, the positive effects are, that it should have as representative organic fertilizers were not confirmed.

Zaplevelení kukuřice a hnojení organickými hnojivy
Robenek, Jakub
In the spring of 2023, field trials were set up on the school farming enterprise Nový Jičín plot to assess weed infestation the application of slurry, farmyard manure, digestate and separate. Liquid fertilisers (slurry, digestate) were applied at a rate of 50 m3, solid fertilisers (manure, separate) were applied at a rate of 50 t/ha. After the application of the selected fertilisers, they were incorporated, followed by tillage and sowing of maize (Zea mays). During the 6th leaf stage of maize, the current weed infestation was evaluated, followed by the application of herbicide, which successfully suppressed the weeds present. The results of the weed infestation showed differences between the fertilization treatments, with the highest weed infestation determined for the manure-fertilized treatment, followed by the digestate, slurry, and separate treatments. On the basis of statistical processing, the following weeds were identified as the most abundant weeds in the manure: red dead-nettle, common field-speedwell, common orache, common amarant, common fumitory, cockspur grass, curled dock, field pansy. The following weeds were present in the slurry: small-flowered cranesbill, cleavers, petty spurge, coltsfoot. The variant fertilised with digestate contained mainly weed species: wild radish, yellow charlock, shepherd’s-purse, field pennycress, field bindweed, rape, fat-hen, creeping thistle. In the part fertilised with separates, the following were mainly represented: field horsetail, mammoth red clover, common chickweed, dandelion, hoary cress, knotgrass, ribwort plantain. The last experimental variant was left without fertilisation, serving as a control. The identified weed species were also used for pH, N, P and salinity analysis as bioindicators. Weed species were divided according to the methodological guidelines into several groups representing certain criteria. During the comparison of the weed species criteria with the theoretical properties and character of the selected fertilizers, a conclusion was established in which the weed indications for each variant could be considered identical to the properties and character of the fertilizers.
