“…Gafurova and Juliev [ 14 ] studied various agro-ecotechnologies to combat crop production challenges in the Aral Sea regions and found that long-term licorice cultivation enriches the soil with organic matter and increases water-resistant aggregates by 70–80%, reduces bulk density up to 1.3–1.4 g/cm 3 and its roots penetrate to a depth of 3.5–4 m, lowers the saline groundwater. Moreover, symbiotic root-nodulating bacteria fix nitrogen from the air and enrich the soil by increasing total N, P and exchangeable K contents.…”

Along with pharmacological applications due to bioactive elements such as flavonoids and glycyrrhizin, licorice has positive influences on the rehabilitation, rejuvenation, and management of salt-affected degraded lands in arid regions. These features made this plant widely appreciated worldwide when climate change is showing detrimental impacts for crop production and food security. However, a growing demand followed by irrational harvesting of wild licorice plants has led to substantial dwindling of its natural habitat. There is an increasing need to protect the plant biodiversity since sustainability can be a problem with wild harvesting. Therefore, it is important to investigate cultivation technologies of licorice under harsh environments, while this plant can adapt to a wide range of climates. Thus, in this review, we studied, analyzed and summarized the literature on licorice cultivation methods counteracting the most common environmental stresses in the Aral Sea region. Particularly, the current knowledge was rationalized regarding on cultivation technologies for alleviating salt stress thereby improving crop production. We also highlighted that future research directions on licorice breeding and genomics that might facilitate to produce more resilient and sustainable licorice genotypes to renovate agricultural productivity under disastrous ecology and climate change of the arid regions. Whereas this area possesses all prerequisite conditions needed for successful cultivation of the alternative cash crop.

“…Soil is a complex substrate and it is quite difficult to accurately determine the factors that regulate microbiological processes in it. Determination of biological processes that have a significant impact on the content of individual nutrients in the soil is an important task, the solution of which leads to an increase in soil fertility [1][2][3]. There is practically no process in the soil in which the microflora would not take part.…”

“…Studies on the importance of biological activity in the formation of soil fertility elements, their morphogenetic, agrochemical, physical, physicochemical properties of degraded soils were also carried out in Uzbekistan by a number of scientists [1,2,10,12,13,15,[18][19][20]. However, studies on the study of the biological activity of the soils of the Jizzakh steppe and the effect of salinity and gypsum content on their current state, based on a comprehensive study, taking into account the peculiar conditions of the region, were not carried out to the proper extent.…”

In the study of soil fertility, biological factors, especially the microbiological activity of soils, have recently attracted increasing attention. Agronomically important groups of microorganisms that participate in the nitrogen and carbon cycle play an important role in soil fertility. By the number of these organisms, it is possible to indicate the state of the soil and characterize the direction of the processes occurring in it. In this regard, it seemed to us necessary to carry out a quantitative account of the main physiological groups of microorganisms involved in the transformations of nitrogen- and carbon-containing substances. The studied area is included in the semi-desert serozem zone with its characteristic geomorphology, climate and vegetation cover. Agrochemical, agrophysical, physical and chemical properties and the sum of integral indicators of the ecological and biological state of soils, it makes it possible to determine the level of impact of their ecological and genetic properties, as well as natural and environmental factors on soil fertility and land degradation.

The problem of soil protection from erosion is relevant for many countries in the arid zone of the world, including the territory of Uzbekistan. In the republic, the main arrays of crops are located on rainfed lands, where the crop is created only due to moisture in precipitation. The amount of porosity (duty cycle) of soils is determined mainly by specific and bulk mass, mechanical composition, and humus content. Porosity of soils decreases from unwashed soils to washed away and down the profile. In the arable horizons of unwashed rainfed soils, it is 52%, washed out - 47.49%. Deeper in the profile, in horizons transitional to soil, due to a sharp increase in density and a decrease in the humus content in all soils, regardless of erosion, Porosity sharply drops to 48-50%. Thus, with a small bulk mass, the overall porosity of rainfed typical serozems is generally satisfactory, since it provides good soil aeration and the use of precipitation, only on highly washed away soils the porosity decreases markedly and the absorption of precipitation is slightly worsened.
