Abstract
This article presents the results of research conducted in desert sandy soils. The study found that the humus content in the soil was moderate in the upper layer, very low and low in the nitrate form of nitrogen, the amount of mobile phosphorus was low in the surface layer of the soil, and very low in the 1 m layer, high and very high in exchangeable potassium.
Highlights
Today, 25% of the world's land is degraded, covering 3.6 billion hectares of land and directly affecting the livelihoods of 1.0 billion people. [1] The main part of degraded lands falls on desert pastures
One of the urgent problems is to develop scientifically based measures to increase the efficiency of desert pasture use, protection of soil cover from degradation processes and their prevention [2]
Several studies are nowadays being conducted in the world to improve the ecological condition of pastures with degraded and low-yielding sandy desert soils and to plant food crops in priority areas [1,2,3]: identification of changes in soil cover as a result of degradation in sandy desert soils; overcoming the negative impact of desert pastures on soils by studying the phytoindicators of degradation; development of technologies to reduce the process of degradation in sandy desert soils by planting promising varieties of desert forage plants, taking into account the properties of sandy desert soils
Summary
25% of the world's land is degraded, covering 3.6 billion hectares of land and directly affecting the livelihoods of 1.0 billion people. [1] The main part of degraded lands falls on desert pastures. One of the urgent problems is to develop scientifically based measures to increase the efficiency of desert pasture use, protection of soil cover from degradation processes and their prevention [2]. Several studies are nowadays being conducted in the world to improve the ecological condition of pastures with degraded and low-yielding sandy desert soils and to plant food crops in priority areas [1,2,3]: identification of changes in soil cover as a result of degradation in sandy desert soils; overcoming the negative impact of desert pastures on soils by studying the phytoindicators of degradation; development of technologies to reduce the process of degradation in sandy desert soils by planting promising varieties of desert forage plants, taking into account the properties of sandy desert soils. In addition to the fact that one of the desert and semi-desert plants has a wide area, the division of it as a polymorphic plant into rocky, sandy, loamy soil ecological types allows it to be cultivated in a variety of soil-climatic conditions [8]
