Abstract
The purpose. To determine influence of dung and composts on its basis on molecular allocation and electrophoretic movability of humic acids, extracted from degraded chernozem by means of biochemical methods of fractionation. Methods. Field, laboratory, mathematical-and-statistical. Results. Influence of dung and composts on its basis on molecular allocation on size and electrophoretic movability of moleculas of humic acids, extracted from degraded chernozem by method of penetrating gel-filtering and electrophoresis in polyacrylamide gel is determined. Conclusions. Importation of compost (dung + husk) promotes formation of resistant against molding humic acids due to augmentation of size and charge of humic moleculas and stabilization of GK in soil.

Key words: humus, degraded chernozem, compost, humic acids, gel-filtering, electrophoresis, dung.
