Resistance of solonetzic soils to rocket and space activity impact in central Kazakhstan.
Introduction. This paper provides the results of a comparative analysis of physicochemical and biological characteristics of soil cover at the fall places of the first stage of “Proton" Launch vehicle (LV) in the area of Yu-2 (Central Kazakhstan). In particular, we considered the ecological stability of brown solonetzic soils in combination with Solonetz soil, to chemical pollution and variability of soil microflora to mechanical stresses during the fall of the separated parts of space launch vehicles (SLV SP). Materials and Methods. We have chosen those Kazakhstan's territories that are used by the Baikonur Cosmodrome as an impact areas of separating parts of space launch vehicles (SLV SP …
Biotechnology of the Recultivation of Technogenically Disturbed Landscapes in the South and East of Kazakhstan (биотехнология рекультивации техногенно – нарушенных ландшафтов наюге и востоке казахстана)
Reclamation of technogenically disturbed lands requires several procedures and assignments. In the South of Kazakhstan during the field development of phosphate deposits, pastoral type lands were disturbed. Reclamation works were done in two stages - technical and biological. The technical stage included the dump planning, loamy ground delivery for bottom lining, layer-bylayer covering and stabilisation. The biological stage included planting of phyto-meliorants, biochar and carbamide insertion under crops. In the city of Ridder, around the mining processing industry, the black humus soil was exposed to aggressive emission of zinc plant. The soil is currently degraded and devoid of vegetati…
