Využití různých technologií zpracování půdy ke kukuřici v podmínkách zemědělského podniku
Daněk, Jan
The literature part of the bachelor thesis deals with soil characteristics, maize sowing and soil processing. In the soil processing chapter, the different soil processing technologies are divided and characterised. The bachelor thesis focuses on the comparison of four soil treatment methods - shallow loosening, deep loosening, medium loosening and plough-ing. A one-year semi-operational experiment was carried out on the land of Agrodružstvo Žimutice. The experiment was mainly focused on the comparison of yield from the differ-ent variants, but other parameters were also evaluated - number of plants per m2, grain moisture at harvest, protein and starch content, bulk density and HTZ. All data were ana-lysed from a one-year semi-operational experiment. The highest yields were obtained with shallow tillage and the lowest yields with deep tillage. However, the yields were not statistically conclusive. Statistical significance was observed for the qualitative parameters of protein content, bulk density and HTZ.

Vliv různých způsobů zpracování půdy na její zhutnění
Chlaň, Filip
The bachelor thesis investigates soil compaction and changes in soil physical properties in different tillage systems. The experiments were based on heavy soil in a potato production area. Three tillage methods were used, the first was ploughing, then shallow tillage and chiselling. For each variant, Kopecky physical cylinders were taken and the penetrometric resistance of the soil was measured on two dates, after tillage and after spring barley harvest. From the Kopecky physical rolls, the reduced bulk density, porosity, minimum air capacity and soil moisture content were determined. Soil resistivity in the soil profile was determined with a penetrometer. Spring barley was then sown in the experiments and its yield was measured to assess the effect of tillage and possible compaction on this parameter. The results show a positive effect of minimization technologies on compaction resistance, whereas tillage was more prone to compaction according to the results. In the first term of measurement, better values of physical properties were recorded for ploughing, but in the second term, ploughing deteriorated. The minimization technologies showed similar values in the first and second measurement. However, the results showed that neither variant showed significant soil compaction with deterioration of soil properties. Similarly, the yield was not different between the variants.

Porovnání různých způsobů zakládání porostů kukuřice seté
Dubový, Miloslav
Maize is one of the most produced crops globally. It has many uses in livestock farming, food production, and industry. With the recent decline in livestock production, the amount of maize in crop rotation has been reduced. However, the production increased again with the arrival of electricity-generating biogas plants. Since most of the land is not covered when cultivating maize in rows, soil erosion occurs. Minimum tillage and soil conservation technologies are used to prevent this side effect, especially on sloping land. The thesis deals with these issues, collects information on various methods of maize cultivation, and compares these technologies in a semi-operational experiment, both from an economic and technical point of view.

Možnosti uplatnění půdoochranných technologií zpracovaní půdy v zemědělském podniku
Leitgeb, Jiří
This bachelor's thesis deals with the evaluation of tillage technologies in an agricultural enterprise AGRO Ořechov, a.s. The work is divided into two parts. The theoretical part deals with the literature. The practical part of this thesis deals with the analysis of the current state of the tillage system in the agricultural enterprise, the possible ways of applying the establishment of field crops by conversation tillage technologies, comparing the suggested system with the existing system and evaluation of the suggested system. In the conclusion of the thesis are described the relevant recommendations.

Sledování utužení půdy na daném pozemku
VONDRÁČEK, Jan
In the thesis is discussed problem with soil compaction in the agriculture in the Czech Republic, causing of aspects of this phenomenon as well as a method suppressing this phenomenon and prevent its. In this work are also mentioned machinery and equipment and their possibilities editing to reduce the compression of the soil. There are also the results of field measurements, which were carried out during the season on land that has been processed by different technology in several of its parts and other measurements carried out occasionally in the Czech Republic to observe the state of soil compaction.

Porovnání výkoností a spotřeb pohonných hmot v přípravě půdy
KUKLA, Martin
In Bachelor thesis threre is analysis the princip of activity of individual types of machines, which are designed to tillage and their effective use. In the thesis there is a question, which preparation of soil is the most suitable in connection with time, which is needed for manage work, demands for fuel and the final yield of harvested crops. For measurement there were created two land on one field, so the soil properties was the same. It means that there is a minimmum of distortion of measurement results

The use of modern stubble plough with minimum tillage
BARTUŠEK, Marek
The aim of this thesis is to broaden knowledge about the possibilities of using modern stubble plough with minimum tillage in agricultural production. In order to evaluate the work of selected indicators stubble machines was based small ? plot experiments at selected station. The experiment was evaluated lumps, depth of tillage and crop residue incorporation of selected machines. Further economic evaluaiton was carried out operating costs of used machines. The use of machines were evaluated according to the results obtained reccomended in agricultural practice.

Evaluation of humus content and quality in different tillage systems
SVOBODOVÁ, Olga
Quantitative and qualitative Soil Organic Matter (SOM) properties were observed in the soil samples of a medium-term field experiment (Cambisol ? Studena, Czech Republic) and an exact field experi?ment (Chernozem ? Gross Enzersdorf, Austria) in the year 2005 considering different soil tillage systems (conventional and minimum tillage). Except the standard parameters, soil organic matter content and quality in particulate water stable aggregates size fractions was additional determinated for Cambisol. Cambisol showed more favourable values of both quantitative and qualitative SOM parameters in minimum tillage system compared to those in conventional tillage system. SOM quality in the water stable aggregates fractions was better in minimum tillage compared to conventional tillage. Cambisol also showed that SOM in aggregates fractions is much more quality compared to SOM in the original soil samples. Chernozem showed higher values of both quantitative and qualitative SOM parameters in conventional tillage compared to those in minimum tillage but the differences are not high. It can be said that Chernozem organic matter reaction to tillage technology changes is slower and of minor rate in comparison with that of Cambisol organic matter. The results of quantitative and qualitative parameters do not conform to the generally recognised values for the Chernozem soil type.
