Abstract

It is established that the humic acids (HA) of tundra soils contain three fractions with a different molecular weight: ≥600, 62–83 and 2,6–5,3 kDa; fulvic acids (FA) — one fraction — 1,5–4,4 kDa. The maintenance of a low molecular weight fraction of HA considerably exceeds a share of medium and high molecular weight fractions. Reclamation of tundra surface-gley soils leads to decrease of a share of high molecular weight and to increase of a share of low molecular weight fraction as a part of HA. Correlative dependences between the contents of HA molecular weight fractions with parameters of HA are established. Refs 16. Figs 1. Tables 3.
