- Abstract (EN)
- The aim of this thesis was the experimental evaluation of thermogravimetry (TG) to assess the status of organic matter supply in agricultural soils. TG is an innovative analytical method for recording thermal mass losses (TML) during heating of soil samples from room temperature to 950 °C. The determination of TML in 10 °C temperature increments (TG indicators) is a central method of TG data evaluation. There is a very close correlation between selected temperature ranges and classically determined soil properties (organic carbon, total nitrogen and clay content). The regression parameters of these relationships can be used to estimate soil properties and to assess the quality of SOM.
