The aim of the diploma thesis entitled "Influence of maize cultivation technology on the amount of organic carbon in the soil and the quality of soil organic matter" was a comparison of quantity and quality non - humidified soil organic matter in various maize cultivation technologies. The work included not only literary research, but even field experiment, thus regular soil sampling, their processing and subsequent analysis. The theoretical part was focused on growing corn in the conditions of the Czech Republic, description, division and importance of soil organic matter, methods for determining its quality and quantity. The practical part dealt with the establishment of a field experiment of maize, soil sampling, their processing and analysis. The obtained values were used to determine the amount and quality of the primary soil organic matter, which was expressed by the rate constant of its oxidation. The obtained data were statistically evaluated in the program STATISTICA 12. The effects of sampling dates, weed control methods and fertilization variants on various soil characteristics were determined.
