metadata.value: The establishment of a network of monitoring sites (term in Russian—«carbon polygons») for
  monitoring climatic processes as well as the emission and deposition of carbon compounds in various
  ecosystems is one of the priority tasks in the field of climate and biosphere conservation in the world.
  This paper presents the results of the study of the soil sections of the «Ladoga» carbon monitoring
  site. Folic Podzol (Arenic) and Fibric Histosol were considered. These soils are widely represented
  in the southern taiga subzone and can be used as benchmark monitoring soil sections. As a result of
  the analysis of chemical parameters, it was revealed that Fibric Histosol and Folic Podzol (Arenic) are
  characterized by an acidic reaction of pH, pronounced podsolization, and peat accumulation. Fibric
  Histosol stores a significant amount of soil organic matter (SOM) up to 42.95 kgC/m2. In the analysis
  of the molecular composition of humic acids (HAs) extracted from the studied soils, it was found
  that HAs from Fibric Histosol were characterized by a relatively high content of aromatic structural
  fragments (27–41%), while in Folic Podzol (Arenic), aliphatic structural fragments prevailed (up to 70%).
  The increase of aromatic structural fragments in the HAs composition indicates the stabilization and
  conservation of SOM. The creation of a monitoring network will make it possible to identify the main
  trends of SOMaccumulation, determine the conditions under which accumulation occurs, and calculate
  its contribution to climate change on the planet.
