The influence of spring floods on the soil condition of Аkmola region

Abstract

The relevance of the research topic is due to the fact that the problem of floods in Akmola region is serious.
The effects of floods are damaging not only socio-economic but also environmental. Seasonal increases in
river levels and further flooding of the surrounding area affect the agrochemical condition of the soil, changing its structure, terrain and biocenosis. The problem is that, to date, no attention has been paid to the study of the environmental impact of floods, but only to the assessment of socio -economic damage, although long-term environmental damage cannot be underestimated either. One of the objectives of this study is to study the impact of recurrent floods on soil conditions that have been flooded in flood plains. Such soils are assessed for management decisions on the future use of these areas. The object of the study of this article are the lands in the floodplain of the Zhabai River, which is the right tributary of the Ishim River in Akmola region. The subject of the study is changes in soil due to floods. The aim of the scientific article is to assess the nature of the impact of floods on the state of the soil, and to develop recommendations for the further use of soils that have been flooded. Soil analyses were carried out in autumn, summer and spring over several years, and the chemical and morphological status of soils was analyzed in dynamics. It is shown how the condition of soils in the floodplain of the Zhabai River changed as a result of floods.
