Dynamika vybraných chemických vlastností povrchových horizontů Velkomeziříčska
Musilová, Martina
This thesis is focused on the potencial (pH/KCl) and the actual (pH/H2O) soil reaction fluctuation and with humus content in 15 different areas in the region of Velkomeziříčsko. There were taken some samples to assess the pH and humus content for three times in the autumn during the years 2011, 2012 and 2013 as damaged from the surface mineral horizon. My work is also consisted with the basic information about the soil reaction, content of humus in the soil, it's determination and the methods of the measurement evaluating and rating. By measuring was found that the average content of humus of the interest area is around 3,7 %. These values correspond to strongly humic soils. The highest content of humus was recorded at forest sites. The average value of actual soil reaction is 6,7 for the field and meadow and 4,2 for the forest. The average value of potencial soil reaction is 5,5 for the field and meadow and 3,3 for the forest. According to the one-factor-analysis of variance there isn't any influence on the date but there is some influence on the location in the statistics of taking the samples to study the change of pH/H2O and pH/KCl. According to the one-factor-analysis of variance there isn't any influence on the date and on the location in the statistics of taking the samples to study the change of humus content.
