Porovnání precizního a konvenčního zemědělství na daném pozemku
POSPÍCHAL, Tomáš
The bacherol's thesis examines the difference between conventional and precision agriculture in tillage and their impact on work efficiency. It focuses tillage methods, guidance systems, conventional and precision agriculture. The practical part of the work compares the impact of conventional and precision agriculture on fuel comsumption, area performance, prime and secondary time on given plot divided into two parts.

Porovnání vybrané sklízecí mlátičky v konvenčním zemědělství a v precizním zemědělství.
VALENTA, Pavel
The diploma thesis on the comparison of the harvest of cereals using the combine harvester in the quality of work is based on the technical literature review, which describes the individual parts of the combine harvester from the harvesting adapters to the threshing device. The methodology of this diploma thesis describes the procedure by which the results and values for the comparison of the Class Lexion 770 TT combine when working in manual control and GPS control (Global Positioning System). Measured, calculated and compared values obtained according to the 2019 methodology. Harvesting of grain crops using the combine harvester is compared in terms of harvest efficiency, harvest losses, machine throughput, performance balance and fuel consumption. The thesis also includes basic economic operating costs.

Porovnání vybraných secích strojů v konvenčním a precizním zemědělství
KRÁSNÝ, Lukáš
This thesis is divided into two main parts. The theoretical part, which contains a brief introduction to sowing, a description of the seed drills that are used for data acquisition, an explanation of the GPS (Global Positioning System) and how these devices work.The second part is the practical part, which deals with the comparison of performance and economic parameters of operation of two selected machines used for seeding, where one is guided by GPS and the other manually.

Mapování pohybu zemědělské techniky s využitím a bez využití GPS
HAŠKOVEC, Luboš
In the thesis the GPS technology is described and functionality of the system is explained. The power and the economic parameters of selected agricultural sets are compared. In theoretic part of the thesis the technology of a global navigaton systems, fundamental principles of its working and its agricultural utilization are described. In practical part of the thesis two control systems via GPS navigation and manual control, respectively, are compared. Measurement was provide on the John Deere 8320R wheeled tractor in agregation with the Strom Terraland TN 3000 H chisel plow in tillage and on the John Deere 8420 wheeled tractor in agregation with the Lemken Solitare 9 seeder in sowing, respectively.

Návrh moderních technologií pro vybraný zemědělský podnik
LÍVANEC, Lukáš
The diplom thesis shows the trend of modern agriculture. Describes precision agriculture its advantages and benefits. It also focuses on elements of precision agriculture, such as global navigation systems, variable applications, dose control by measuring the content of substances in a given commodity, software solutions for field and machine management and the principle and function of machines for the application of plant protection substances. In the main point, he analyzes the machinery of the Chyšky Agricultural Cooperative, where he selects the weakest link and proposes a new suitable technology for the existing one, then evaluates everything economically.

Možnosti využití online senzorových systémů pro variabilní aplikaci dusíkatých hnojiv
Škrabal, Jakub
This bachelor thesis describes the possibility of using spectral measurement of nitrogen fertilizers in variable application especially on winter wheat. The theoretical part describes the fashion and the principle of spectral measurement and the essence of nitrogen in field´s crop nutrition. This part also lists sensors available in the market. In a practical part of the thesis there is a description of operational experiment in which the Isaria sensor from Fritzmeier company was tested. This sensor has been tested for two years on winter wheat. In a argumentative part of the thesis there is a comparison of the results from this two experimental years and the evaluation of each variant of the sensors setting. The focus was specially on the following indicators: quantity of applied nitrogen, the utilisation´s efficiency of nitrogen on production unit and the content of nitrogen´s substance in grain and yield. Moreover there are mentioned the economic effects of the difference in uniform and variable dosage of the nitrogen fertilizers.

Mapování heterogenity půdních podmínek v precizním zemědělství
Oudová, Barbora
Precision agriculture is an agronomic approach that aims to optimize inputs into agricultural production to achieve balanced, qualitatively and quantitatively the best possible yields, while minimizing the financial costs and maintain or improve the environment. The basic premise of this approach is the knowledge of soil conditions of land used for agricultural production. This information can be found in agronomic records, soil maps or results of agrochemical testing. Indirect methods of soil heterogeneity mapping based on the principle of sensor measurements and remote sensing are also available. Indirect methods for determining the physical-chemical properties of soil are generally user-friendly, cheaper, faster, and have a higher density of measurement points than the sampling of soils. Comparison of direct and indirect methods showed that indirect methods provide a detailed picture of soil variability. However, interpretation of results is affected by many other factors, which are based in the principle of soil het-erogeneity itself.

Vyhodnocení heterogenity výnosu plodin a ověření senzorového systému pro variabilní aplikaci hnojiv
Mezera, Jiří
In the theoretical part of this thesis there is summarized basic knowledge about precision agriculture, soil condition monitoring, mapping yield and state of vegetation. The practical part deals with evaluation of yield heterogeneity, creating yield maps, and verification of Isaria online sensor system for variable application of nitrogen fertilizers. The methodology of the work was based on the collection of data from the Isaria sensor system and the yield data from combine harvesters on the land of Zdounky center of SALIX MORAVA a.s. during 2016. The available documents were processed using tools in geographic information systems and then statistically compared to each other, including the underlying maps of the yield potential and satellite data of remote sensing. The significance of dependencies of the above mentioned factors was evaluated by correlation analysis and linear regression. The results show that the varying degrees of dependence were found between variables.

Využití bezpilotního průzkumu v precizním zemědělství
Horniaček, Igor
Thesis deals with the use of unmanned imaging in precision agriculture. Explains what a precision farming is, describes remote sensing, a history of drones, the causes of soil variability, evaluation of the condition of crops, how we can monitor and process the matter in understandable form of output for a farmer. The own work explores the concrete evaluation of the results from the semi-operational field trials and evaluates the use of unmanned land monitoring systems.
