The current condition of soil organic matter in Stropnicko selected sites
BOROVKA, Jan
The main objective of this thesis was to determine the current status of soil organic matter (SOM) in the Stropnice River basin based on the collected soil samples. SOM is a major source of carbon in the soil. The amount of soil organic carbon (SOC) in the samples was measured using the FORMACSHT TOC / TN analyser, as well as the additional module PRIMACSMCS (fa Skalar - CARBON Instruments Ltd.). The values measured in 2014 were compared according to the land use (woodland, grassland, arable land) and the depth of sampling (A: 0-15 cm, B: 15 - 30 cm, C: 30 - 45 cm). Furthermore, these values were compared with values from 2001 and 2007. The highest SOC concentration was found in the upper layers of forest soils, grassland soils showed lower SOC content, whereas the arable land showed the lowest amount of SOC. Over the time, depletion of SOC is evident for all categories of land use.
