Abstract
The article considers the issues of phytoreclamation of saline soils by cultivating licorice (Glycyrrhiza glabra) and its effect on their nutrient regime. The relevance of the research is that in the southern half of the Republic, saline soils have a tendency to steadily grow not only due to changes in soil formation factors, but also due to increased anthropogenic impact. Their development is achieved by a classic method, the essence of which is the leaching of salts from the soil and ground layer against the background of a drainage and collector network. The main disadvantage of the noted method is the use of a huge amount of water. In this regard, the purpose of the research was to determine the effects of licorice on the nutrient regime of saline soils of Southern Kazakhstan with different levels of salinity to develop a biological method of reclamation. The advantage of the latter over similar methods is that when growing licorice, a large volume of water is not spent, and due to the biological characteristics of the plant, it carries easily soluble salts with the above-ground mass, ensures a decrease in the level of groundwater and enriches the soil with organic matter.
Field experiments were conducted on the territories of three pilot farms in Southern Kazakhstan, which differ in the level of soil salinity. The studies showed that growing licorice in conditions of slightly, moderately and strongly saline soils does not affect the provision of soils with humus.
