Poly-Species Phytocenoses for Ecosystem Restoration of Degraded Soil Covers

Agroecological studies are based on the concept that, by understanding ecological processes, it is possible to manage agroecosystems for more sustainable production of biomass and, thus, protection natural resources. Many in field agroecology show that some farming methods can improve soil quality and restore increasing plant biodiversity. Functional characteristics plants assessment ecosystem processes services be used management agroecosystems. The paper discusses ways pastures with low biological productivity arid steppe Northern Kazakhstan (Kostanay region). Grass-and-legume mixtures were selected, according climatic conditions this region, increase pastures. authors also describe meteorological region question 2021. data agrochemical analysis which grass mixture was grown differed slightly from soils other sites often even inferior them indicators affected productivity, namely, humus, phosphorus, potassium content. In experiment, highest shown grass-and-legume consisting crested wheatgrass-alfalfa-awn less brome (27.8 c/ha green mass 12.6 dry matter). Thus, information obtained during study, concluded Kazakhstan, necessary select have nutritional value adapted region. algorithm predictive simulation model dynamics graminoid community presented a general form. Problems related remediation covers discussed.
