The process of productivity in the community of common fescue-lerh wormwood (Artemisia lerchiana, Festuca valesiaca)

Abstract

The article presents the results of the study in accordance with the internationally accepted biological program of productivity, intensity of productivity-destructive processes and biological cycle of nitrogen and ash elements in the plant-soil system in the community of common Fescue-Lerh Wormwood (Artemisia lechiana, Festuca valesiaca). The studied area is located in the northeastern part of the Ural plateau in the Shelek district of Western Kazakhstan in a slightly undulating temperate dry-steppe zone with a slope to the valley of the Elek River in the Konchubai gully with dark chestnut carbonate-saline soils. The communities in the studied area are very important in pasture and forage farming. But under the influence of recent anthropogenic factors, vegetation and soil cover in plant communities are undergoing changes, the diversity of plant species is decreasing, biological productivity is decreasing, the circulation of chemical elements is changing, and plants of forage importance are being replaced by weevils. The community of common Fescue-Lerh Wormwood is characterized by moderate desertification, moderate digression. This community has decreased to 70% of the species diversity, and plants of forage importance have declined and have been slowly replaced by plants that are poor in feed. As a result of the effective use of this community can be restored.
