metadata.name: dc.description.abstract
metadata.value: Evaluation of humus accumulation and humification rates was conducted on
  soils affected by surface and crown fires during 2010 forest fires near Tolyatti
  (Samara region, Russia). Three key soil plots were studied for estimating SOM
  quality changes under the forest fire effect. Total carbon and nitrogen content,
  as well as Сhumic acids/Cfulvic acids (Cha/Cfa) ratios, were estimated to evaluate the dynamics
  of soil recovery. Humic acid powders were extracted from soils and analyzed
  by elemental composition and 13C-NMR spectroscopy to assess changes
  in structure and composition. The data indicate that the burning of a forest
  floor and humic horizon led to humus losses and decreases in total carbon
  stocks and content. As a result of the fires, the content of humic acids in the
  pyrogenic horizon increased. Greater increases in the degree of organic matter
  humification were observed for surface fires than for crown fires. Fire also
  lead to the formation of humic acids with an increased proportion of aromatic
  compounds than in control soils, which indicates the degradation of carboxylic
  and aliphatic groups of molecules under the burning effect. This corresponds
  well with the decrease of the proportion of hydrogen when comparing the elemental
  composition of burned soil with that of mature soil.
