Hodnocení technicko-ekonomických parametrů traktorových souprav na zpracování půdy.Janů, Radek January 2019 (has links)
The Master’s thesis presents contemporary methods of soil cultivation. Emphasis is placed both on conventional soil tillage and minimum tillage practices. Different methods of tillage are systematically classified and characterized, and machines for individual methods of soil cultivation are introduced. The second part contains the methodology of field measurement of Fendt 924 Vario, John Deere 6215R Plus, and Pöttinger Servo Plus 6.50 plow, Pöttinger Synkro 3020 plow, Pöttinger Synkro 6020 NOVA, and Pöttinger Terradisc 6001 T. It follows from the measured values that higher performance was achieved with the plow stubble cultivator, while lower fuel consumption for the cultivation of 1 ha of land was achieved during plowing.

Vyhodnocení ohroženosti pozemků vybraného katastrálního území vodní erozíZámečník, Tomáš January 2014 (has links)
This thesis is focused on evaluation of vulnerability of land cadastral area Rovečné water erosion and proposing specific erosion control measures. The intensity of the water erosion was determined by calculating the Universal Soil Loss Equation according Wischmeier and Smith. The calculation of the universal equation and determine the long-term average soil loss by erosion prior to the proposal and the proposal of its own anti-erosion measures was realized through the ArcGIS. Calculating factors universal equation was found that 213.80 ha (26.10% area) occurs very strong erosion, that has been proposed measures completely eliminated. The 156.34 ha (19.08%) there is a strong erosion, on 82.16 ha (10.03%) there is medium erosion and on 366.90 ha (44.79%) is a slight erosion. The proposed anti-erosion measures were mainly the introduction of the minimization tillage the cultivation of crops. For a comprehensive erosion control of area where was persisting increased erosion was designed protective grassing.

Vliv odlišných technologií zpracování půdy na plevele v polních plodináchZemánek, Václav January 2015 (has links)
The thesis is focused on technology of tillage and its effect on weed infestation of spring barley. The observations were done in years 2012, 2013 a 2014 on fields in Zabcice owned by Mendel University in Brno. The three different technologies of tillage were observed. The detected results were processed by CCA (Canonical Correspondence Analysis). During the traditional tillage were observed the less weed infestation, there were mainly species like a Silene noctiflora, Cirsium arvense, Fallopia convolvulus and Capsella bursa -- pastoris. The largest weed infestation was observed during minimalistic tillage. There were mainly species Thlaspi arvense, Amaranthus sp., Chenopodium ficifolium and Polygonum aviculare. The tillage with direct sowing encounters mainly species Taraxacum Ruderalia, Convolvulus arvensis, Plantago major and Echinochloa crus -- galli. It is obvious from the results that the weed infestation is influenced by the technology of tillage and the weather of that year.

Vliv vybraných agrotechnických faktorů na stav půdní organické hmoty při dlouhodobém pěstování jarního ječmeneŠanderová, Pavla January 2016 (has links)
The aim of the thesis is to make an evaluation of the impact of agro-technical factors (tillage, crop rotation), in the total amount of oxidizable carbon Cox (%) on a long-term grown spring barley. Measurements were carried out in 2014 and 2015, excluding these years from long series of observations. It is a stationary experiment in sugar beet growing region which runs continuously since 1989. The experiment has been established by Mendel University in Brno - Ivanovice in Hana on the cultivated land owned by Crop Research Institute, v. v. i. In Prague - Ruzyně. The observations were made in two rotations with 33.3% and 66.6% share of cereals. There were compared four variants of the tillage and samples were taken from three depths. The Cox monitored impacts were statistically demonstrated in all the variables (crop rotation, tillage and sampling depth). There was also found higher concentration of Cox in the crop rotation with 66.6% cereals representation. While tillage monitoring, the highest amount of Cox was seen by use of tillage equipment in the extent of 0,10 metres. On the other hand, the lowest amount of Cox was found by direct seeding into a soil. Also, it was found that the amount of Cox decreases with depth of sampling in both monitored years.

Uplatnění technologií diferencovaného zpracování půdy při pěstování kukuřiceMytyska, Václav January 2017 (has links)
The theoretical section of this thesis addresses corn characteristics and growing. Subsequently, it describes particular tillage technologies dividing them into conventional mouldboard ploughing technology, minimum tillage and introduces strip-till technology as a separate chapter. The major part describes the founding and evaluation of a 2016 field trial for study of different tillage technologies in terms of impact on silage corn growth quality, yield and physical characteristics of soil. The trial was based on five different technologies in two terms - strip tillage, ploughing and minimum tillage with two distinct tools at three depths. For trial evaluation, following parameters were observed: plant count, weight and height, dry matter content and yield and soil penetrometer resistance. The trial outcomes are commented and compared with trial results of other authors.

Využití hloubkového kypřiče při pěstování obilovin a řepky olejnéMICHEK, Aleš January 2019 (has links)
The diploma thesis deals with the comparison of two technologies for soil cultivation in winter rape and winter wheat growing in 2017 and 2018. The first technology is a conventional technology, or classic using plowing and the second one is a minimization technology, where plowing is replaced by loosening. The work is focused on the comparison of fuel consumption, investment and operating costs, exploitative indicators and machine work quality. Furthermore, the thesis is focused on the description of particular machines and the company of primary agricultural production, where the machine is used.

Vliv minimalizační technologie zpracování půdy na regulaci plevelů v porostech obilnin / Effect of tillage minimalization technology to control weeds in cereal cropsSTEJSKAL, Martin January 2013 (has links)
This diplom thesis deals with the evaluation of quality machines work for soil cultivation used in minimalization soil cultivation technology and weed control in cereal crops. The machines were evaluated for incorporation of harvest residues, uniformity of depth and size of lumps. It was further performed an economic evaluation of selected cost per operation soil cultivation. In order to monitor the development of weeds was based small-plot experiment, where was monitored representation of individual weed species and the effectiveness of selected herbicide.
