Composition of organo-mineral complexes migrating in soddy-podzolic soil (Umbric Albeluvisols Abruptic)
In laboratory column experiments carried out on soddy-podzolic soil reclaimed by industry wastes, the composition of organo-mineral complexes (OMC) migrating during the washing was studied. Carbon from OMC precipitated at pH 13, and ranged from 5.5 to 5.7%, regardless of the particle sizes of applie...

| description | In laboratory column experiments carried out on soddy-podzolic soil reclaimed by industry wastes, the composition of organo-mineral complexes (OMC) migrating during the washing was studied. Carbon from OMC precipitated at pH 13, and ranged from 5.5 to 5.7%, regardless of the particle sizes of applied ameliorant. The optical density (Есg ml-1) of OMC solution was 2.7 to 3.1, which is within the range typical forfulvic acids. The total amount of Ca, Mg, Sr washed out from the OMC depended on the size of the ameliorant particles, as well as the content and ratio of alkaline earth metals in it. The smaller the particle size was, the migration losses of Ca, Mg, Sr were higher. The presence of significant amounts of Mg in the ameliorant enhances unproductive loss of the bases. According to the ability to migrate in the OMC, the studied elements can be arranged in the following descending order: Mg> Ca> Sr. Unexpectedly new finding was that not all organic substances migrating in the profile of reclaimed soddy-podzolic soils can precipitate under the conditions of a strongly alkaline reaction of the medium. |
