The contents of SO4 of gypsum and magnetic susceptibility

The contents of SO4 of gypsum and magnetic susceptibility in the soils of the studied short-term chronosequences. The magnetic susceptibility (MS) of air-dried and sieved samples was measured in the laboratory using a unified procedure of measurement on the Kappabridge KLY-2, producer «Agico» (Brno, Chech Republic). The magnetometer belong to the Centre of Collective Use, Institute of Physical-Chemical and Biological Problems of Soil Science, Russian Academy of Sciences, and the mentioned analyse was performed there.
