SOIL INVERTEBRATES AS BIOINDICATORS OF ANTHROPOGENIC IMPACTS ON THE DIFFERENT FUNCTIONAL GROUPS IN THE IRRIGATION AND RAINFED AREAS OF SOUTHEAST OF KAZAKHSTAN

Abstract

The work is based on the study of influence of anthropogenic impacts on soil biological activity in comparison with its main indicators, which allowed to establish the soil fauna correlative connection with major traditional indicators of soil fertility, and significantly enhances their ecological importance in the assessment of agricultural techniques in agricultural production. In Kazakhstan such researches have a fragmented character, soil animals and their effects on soil properties have been studied poorly. The reason for the relatively poor knowledge of soil animals is not only the complexity of the conditions for the existence of organisms in the soil, but also the difficulty of observation and study of the soil fauna due to the opacity and density of habitat. And, despite the importance of soil fauna in the soil-forming process, in Kazakhstan it is still poorly understood, especially in the agro-technical influences in irrigation and rainfcd areas of south-eastern Kazakhstan. Lack of information on the biological activity in this area, the underestimation of the role of soil invertebrates and their value in the formation and reproduction of soil fertility, lack of methods of biodiagnostics and indication of soil identified the relevance and need for systemic research in this direction.
