Composition of organic-mineral complexes (OMC) migrating in the reclaimed sod-podzolic soils (Umbric Albeluvisol Abruptic)

Composition of organic-mineral complexes (OMC) migrating in the reclaimed sod-podzolic soils (Umbric Albeluvisol Abruptic)

The composition of organo-mineral complexes (OMC) migrating from the arable horizon limed by Umbric Albeluvisol Abruptic was studied. The carbon content in organic-mineral complexes (OMC) ranged from 5.5 to 5.7%. The optical density index (Esmg/ml) varied in the range of values from 2.7 to 3.1, char...
