APPLICATION OF MODIFIED HUMIC COMPOUNDS FOR RESTORATION OF DESERTIFICATION IN MANGISTAUS REGION

Abstract

In this article considered agrochemical experiments of modified humic preparations in the field conditions which carried out in the Mangistau region (Senek, Ushtagan, Tushchykadyk) on the black saxaul and zhuzgen crops. It is established that their use allows obtaining a high yield of saxaul seedlings of black and zhuzgen in nurseries. It has been revealed that the application of modified humic preparations contributes to the formation of a more branched and powerful root system, to an increase in the coefficient of soil moisture use by plants, to regulate the yield of nutrients and to improve the mineral nutrition of plants, to shorten the periods of their vegetation (by 10-15 days), to enhance the protective action of plants adverse factors. The survival rate of black saxaul and zhuzgen saplings transplanted from the nursery to mobile sand (over 2000 pieces each) was 94-98% and 67-72% in control variant in the absence of irrigation. The tests carried out over three years have shown that the application of modified composite humic preparations leads to an increase in the areas occupied by saxaul and zhuzgen (total forest area is more than 250 ha), stopping mobile barkhans and fixing sand.
