Structural and Functional Composition of Humic Acids Isolated from Soils of Natural and Urbanized Territories of the European Far North and the Arctic

The structural and functional composition of humic acids in natural urbanized areas the European Far North Arctic has been studied using modern physical chemical research methods. It is shown that content fulvic for most soils higher than acids; soils, process humus formation humate (replantozem, pelozem humus-peat soil), humate-fulvate (turf soil, culturozem urbanozem) fulvate type (gleezem lithozem); macromolecules himatomelanic are predominantly aliphatic nature, with a high proportion aromatic fragments, FA have an structure. In addition, located more Northern regions characterized by oxygen-containing groups compared to preparations South peat)
