Boracium form availability and ratio in the soils with different boracic salinization degree in the Om-Irtysh interfluve

The research results of the boracium form availability and ratio in the meadow chernozemic soil with normal level of its availability and sodium soil with strong boracic salinization are considered. Substantial differences between them in terms of availability of gross, water-soluble, mobile, acid-soluble boracium are determined. The data on the readily soluble boracium particle availability in soils that is specifically adsorbed, fixed with the oxides of iron, aluminum, manganese and organic matter are given.
