	Machines for precision agriculture - preparation of teaching materials NĚMEC, Jiří The bachelor's thesis deals with technologies for determining the variability of land and vegetation. Attention is also paid to the issue of yield maps and navigation systems, the use of which in agriculture is constantly increasing. Detailed record
	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. Detailed record
	Vyhodnocení variabilní aplikace hnojiv senzorovým systémem Isaria Škrabal, Jakub This diploma thesis concerns the evaluation of a four-year sensor testing of the Fritzmeier ISARIA system. In a literature review is described nitrogen variable fertili-sation, the diagnostics of nutritious plant condition. The sensor system ISARIA is also described including vegetative index and individual modes settings. In a practical part is described four years testing of the Fritzmeier ISARIA system in a company Salix Morava a. s. in Zdounky region. In results there are listed parameters like yield, the quantity of applicated nitrogen, the effectivity of nitrogen application the quality of production and revenues. The results shows significant economic and environmental effects resulting from variable nitrogen application. The results are also statistically evaluated for enabling to be a part of a conclusion. It can be seen form the results, that a significant, impact for an economic contribution of a variable nitrogen application is affected by a field, year, cultivar, but also by settings of a sensor system.
