Vliv vodní eroze na kvalitu půdní organické hmoty ornic černozemí Hustopečska
Konrádová, Pavlína
This bachelor thesis deals with the effects of water erosion on the quality of soil organic matter of chernozems of Hustopeče area. Samples were taken in September 2012 on five different plots and they were Horní Bojanovice, Hustopeče, Krumvíř 1, Krumvíř 2 and Němčičky and the content of humic substances, whose contents and the ratio is the main criteria for assessing the quality of the soil organic matter. Samples were taken on sloping plots in the top, middle and the bottom of the slope. The average value of the ratio HA: FA for the upper part of the slope is 0.73, the middle part of the slope 0.67 and the lower part of the slope 0.97. The average value of the entire slope of the Hustopeče plot was 0.77, Krumvíř I 0.75, Krumvíř II 1.19, Němčičky 0.67 and Horní Bojanovice 0.57. The limit value ratio HK: FK is 1. Thus land with a value greater than 1 is, according to the publication Pedobiologie a mikrobiologie selected chapters from the L. Růžek a K. Voříškek, soil with the highest quality of soil organic matter. This value was then measured at only one plot and that was on Krumvíř II, we can therefore say that, soil organic matter is the best here. Those with the lesser quality then decreese below 0.5. Based on statistical metod of single-factor analysis, the influence of water erosion on to the change of the quality of soil organic matter is inconclusive

Kvalita humusu půd vybrané části Českomoravské vrchoviny
Pinteš, Lukáš
This bachelor thesis is focused on humus quality. They were samples taken from a chosen part of Českomoravská vrchovina, specifically from the Velkomeziříčský bioregion (16 locations). The samples were taken from Nové Město na Moravě and also northerly of the motorway D1 between Jihalva and Velké Meziříčí. The quality of humus was determined by the method Kononová-Bělčikova, which is based on fractionation of two, for humus typical substances, humic and fulvic acid. The thesis briefly introduces the soils as a whole and the causes of its origin. Furthermore, the work is focused on the organic fraction and its origin, meaning, composition and quality determination of humus. There are also characteristics of the area of interest, accompanied with some maps, processing soils samples, its evaluation and comparison of results with the neighbouring locations and literature.
