This article presents the results of a reconnaissance survey of agricultural lands of LLP «Kazger» in the Birzhan sal district of the Akmola region to determine the lowest terrain levels and identify locations where drainage meltwater accumulates. A chemical analysis of drainage meltwater was carried out to determine oxygen conditions, organoleptic indicators, water mineralisation, the content of biogenic substances, heavy metals, and toxicants. According to organoleptic indicators, total mineralization, total hardness, pH of the environment, content of SО42−, NО3−, Сl−, СО32−, Са2+, Мg2+, ∑Na + K, Pb2+, Sr2+, Astotal all tested samples correspond to class 1 water quality, i.e. water from reservoirs of «very good quality». According to the COD and BOD5 indicators, all water bodies are characterised as «highly polluted», corresponding to pollution class 5. The CODdichr, BOD5 indicators indicate severe pollution of water bodies with organic substances. Pollution of all water bodies with ions is observed: НСО3−, Ptotal, Al3+, Zn2+, Hgtotal, ∑Fe2+, Fe3+. The most polluted is reservoir № 1. For the contour-strip organization of agricultural lands using the Potapenko-Lukin-Zverev method in combination with technologies for accumulating drainage melt water, recommendations are given on the species composition of mixed, drought-resistant, salt-tolerant forest crops.

摘要

This article presents the results of a reconnaissance survey of agricultural lands of LLP «Kazger» in the Birzhan sal district of the Akmola region to determine the lowest terrain levels and identify locations where drainage meltwater accumulates. A chemical analysis of drainage meltwater was carried out to determine oxygen conditions, organoleptic indicators, water mineralisation, the content of biogenic substances, heavy metals, and toxicants. According to organoleptic indicators, total mineralization, total hardness, pH of the environment, content of SО42−, NО3−, Сl−, СО32−, Са2+, Мg2+, ∑Na + K, Pb2+, Sr2+, Astotal all tested samples correspond to class 1 water quality, i.e. water from reservoirs of «very good quality». According to the COD and BOD5 indicators, all water bodies are characterised as «highly polluted», corresponding to pollution class 5. The CODdichr, BOD5 indicators indicate severe pollution of water bodies with organic substances. Pollution of all water bodies with ions is observed: НСО3−, Ptotal, Al3+, Zn2+, Hgtotal, ∑Fe2+, Fe3+. The most polluted is reservoir № 1. For the contour-strip organization of agricultural lands using the Potapenko-Lukin-Zverev method in combination with technologies for accumulating drainage melt water, recommendations are given on the species composition of mixed, drought-resistant, salt-tolerant forest crops.
