Physico Chemical

In 12 astatic pools, each of which was characterised by the dominance of phytocenoses of one of three plant associations, investigations were performed on the physico-chemical properties of the water and bottom sediments, in order to establish the relations between the habitat conditions and vegetation. The criterion of the degree of saltiness of the bottom sediments and the specific conductivity of water in these water bodies allows to order them according to their decreasing fertility as follows: 1) water bodies with dominant phytocenoses of the association <em>Equisetetum limosi</em>, 2) with <em>Caricetum elatae</em>, 3) with <em>Typhetum latifoliae</em>. The type of vegetation indicates also connections with other properties of the water (hardness, oxidability, pH, chloride content) and of the bottom sediment (organic matter content, chlorides, magnesium and various forms of nitrogen). Correlation between the chemical composition of the water and depostis has only been demonstrated in the case of chlorides.

Effective Use

The ways of processing large-tonnage coal mining waste – oxidized coal into technical and agricultural products – are presented based on the rational and efficient use of some modified physico-chemical properties of original coal materials. Studied ways of rational use of oxidized coal in agriculture, based on effective use of coal derived humic acids: as an additive of its crushed fractions on the fields for growing grain and tuberous plants, as well as for the production of humic preparations (fertilizes, biological active additives based on humic acids for arable farming and animal husbandry). Proposed new methods of reclamation of disturbed lands with the help of microbiological destructors of oxidized coal.
