Porovnání biologických a chemických vlastností orných půd a půd pod trvalým travním porostem
Bystřická, Lucie
Diploma thesis is focused on assessment of soil chemical and biological properties of Haplic Cambisolin different types of land use (permanent grassland and arable soil, intensively used in agriculture). Field experiments are carried out at the Forage crops Research Station of Mendel University in Brno at locality Vatín. Selected soil parameters such as humus content and quality of humic substances, soil reaction, water extractable carbon content, amount of microbial biomass, and basal soil respiration and substrate inducted soil respiration were determined by commonly used standard methods. Measured data set during 2017 and 2018 was statistically evaluated using program StatisticaCZ12, software (StatSoft software Inc., Tulsa, Oklahoma, USA). Obtained results shown statistically significant differences between arable soil and permanent grassland in total organic carbon content, humic substances content,amount of microbial biomass, water extractable carbon content, basal soil respiration.

Obsah mikrobiálního uhlíku v půdě při různém způsobu obhospodařování
Hábová, Magdalena
Diploma thesis deals with stabile and labile organic carbon forms in soils. During 2009 - 2011 selected soil parameters in soil under different management were studying. Following parameters were chose - total organic carbon, labile carbon, and microbial carbon, content of humic substances, humic acids, fulvic acids, and basal soil respiration. Object of study was Luvic Chernozem (Unčovice), Haplic Cambisol (Vatín), and Haplic Luvisol (Lesonice). Soils were under classical tillage and minimum tillage system, and permanent grassland system. Obtained results showed that all studied soil types had satisfying content of total organic carbon and total nitrogen for soil microorganisms. The highest labile carbon content, microbial biomass and basal soil respiration was determined in permanent grassland soil.
