CHANGING THE PROPERTIES OF CULTIVATED LAND IS A REAL BASIS FOR THE FORMATION OF NEW ENVIRONMENTAL NICHESI.S. Belyuchenko and O.A. Melnik
Ecological niche, reflecting the function of a species or population of social mechanisms, characterizes a set of necessary factors. Each species performs a certain function, caused by its properties and needs for food resources, ways of reproduction, structural features, and limits of resistance to environmental conditions. When mixing lyophilic and lyophobic waste systems, they coagulate with the convergence of particles that retain their original shapes and sizes and are combined into dense aggregates. Unstabilized and unstable lyophobic waste systems change their dispersed composition towards strengthening the particles until complete separation of microphases. Stabilized lyophilic systems retain dispersability over a long period of time. Hydrophobic coagulations of various wastes are distinguished by the separation of a complex disperse system into gaseous, liquid and solid phases. Colloidal particles are structured in solution and form a variety of aggregates that fill the entire volume of solution. Good conditions for the development of individual species increase the productivity of the organic mass, which will subsequently be determined by physicochemical properties of soil medium, gaseous and hydrologic system. Introduction of complex compost in the surface soil expands environmental niches, improves the supply of plants with macro- and microelements, moisture, carbon dioxide, which increases the efficiency of leaf apparatus and root system and expands the development of new living organisms in cultivated land. Complex composts, new environmental niches formed with their help, strengthen soil buffering in relation to pollutants, organic substances, clay complexes, ion-exchange, reducing-oxidizing, acid-base and sorption properties.
