ENERGY INDICATORS OF BIOMASS INVERTEBRATE ANIMALS IN SOILS DRY-STEPPE ZONE OF AZERBAIJAN

Abstract

The study of the formation of the biomass of invertebrate animals inhabiting the drysteppe zone of Azerbaijan is an important and necessary criterion for determining their biocenotic role. The energy estimate of the biomass of invertebrate animals in gray-brown and blackearth soil is a bioenergetic indicator characterizing the participation of individual groups of pedobionts in the transformation of energy and the geochemical cycle of substances. Studies have shown that the total energy accumulated in the biomass of invertebrate animals in fused chernozems of the natural cenosis under grassy vegetation was 1197, 10 cal/m². On the agrocenosis of alfalfa, the energy indicators increase to 2915, 31 cal/m². In the biomass of invertebrate animals, gray-brown soils of the natural cenosis under the wormwood-ephemeral community, 3166.91 calories/ m² of energy were accumulated. On the agrocenosis of alfalfa, the energy index of invertebrate biomass is significantly increased to 6598, 30 cal / m² compared to the same price of the previous soil. Unlike gray-brown soils, the merged chernozem horizon negatively affects the qualitative composition of invertebrate animals and their energy indices.
