| Summary: | The objective of the article was to determine the effectiveness of lime of different origin for chemical amelioration of soils and examine its impact on soil functions such as productivity, habitat, regulation of water quality, and the protective buffer biogeocenotic screen. Limy ameliorants were applied in small local field experiment on Luvic Chernozem, and experiment with lysimeter columns was carried out on Albic Luvisol. The number of the main groups of microflora and enzymatic activity of soil was determined in soil samples taken for the analysis from the root zone. Research concerning the influence of natural and industrial origin ameliorants on soil as habitat showed the correlation of sugar beets productivity with soil biogenic. The increase of biomultiplicity of soil microbiota after addition of a cement dust and negative influence of red sludge on soil as habitat for living organisms was observed. Research involving the influence of ameliorants on soil by lime as the protective buffer biogeocenotic screen was carried out using lysimeter columns. It was stated that the addition of limy ameliorants reduces mobility of heavy metals.
