Description
In the geochemical laboratory, individual chemical parameters of the soil samples are investigated. Element determination is done using ICP-OES. Among other things, there are determined:
1) the pH values with the glass electrode,
2) the lime content with the Scheibler apparatus,
3) the conductivity of the soil,
4) the cation exchange capacity (abbreviation: KAK, T-value), and
5) the mass of the organic fraction of a sample by measuring the ignition loss in the muffle furnace.
