Hodnocení utuženosti půdy v kolejových řádcích za použití minimalizačních technologií
Daněk, Tomáš
This paper describes and quantifies the differences soil physical properties in rail lines in winter wheat and winter rape. Both crops were grown on adjacent land, which have the same BPEJ. Sampling was conducted once during the growing season and the second time just after the harvest of rape, and just before harvest wheat. In each term sampling, samples were taken at 3 repetitions for each plot. Samples were taken in the track in the space between the rails and the control was between sessions. Both crops are used to process the soil before sowing minimization. The differences are expected to land in one of the same crop, as well as differences between crops. Due to different agrotechnics rape and wheat, where the entrances to rape more mechanization, we expect more consolidation in the tramlines rape.

Měření vertikálního zatížení pod jednotlivými nápravami traktorů s připojenou nesenou technikou
ŠÁLENÝ, Miroslav
This bachelor thesis solves problems of vertical load under each tractor's axle with attached mounted agricultural technology. The aim of this work is to describe the impact of modern agricultural machinery and its impact on the agglomeration of agricultural land and the reasons for the penetration. Then it describes the methods that limit soil mitigation. In the practical part, several load measurements of tractors with agricultural support technology were carried out under the front and rear axles. Then the calculations reckoned the weight acting on one square centimeter. The results of the measurements were evaluated at the end of the work.

Utužení půdy jako důsledek činnosti zemědělské techniky
MASOPUST, Jan
This diploma work is dealing with the issue of compacted arable land made by agricultural equipment, in the Czech Republic. The first part of the thesis introduces factors that causes the compacted soil. Then, we are looking at the ways how to prevent the compaction or, on the contrary, how the undesired compaction can be removed or at least minimalized. This is analyzed in detail according to factors that may influence the process of the land compaction, such as the actual weight of the agricultural equipment kit combination, the choice of the correct tires and the economy of plant growing.

Program COMSOL Multiphysics jako prostředek pro simulace utužení půdy pojezdem zemědělské techniky
STANĚK, Jakub
This bachelor work is concerned with an applicability of the program COMSOL Multiphysics as a device for a simulation of a solidify of a land. The work is composed of four thematic units. In the first one the land is described shortly and its basic property. The second unit is about problems of a solidify of a land under the influence of a roller of farming machines and its results. The third part is pointed on the software its functions, additionals function and in the end on a short sequence of action, that is essential to do for making a model. On the last part the all process is described for creating of a multiphysical task with concrete numbers, that pretends loading of the land and its deformation due to a effect of weight of a farming machine.
