The article describes the influence of licorice on hard-to-reclaim lands, in order to obtain valuable roots and improve soils. The creation of a salt regime of the soil on irrigated lands is achieved only through the implementation of a complex of reclamation and agrotechnical measures, and the most important is the cultivation of licorice. For a comprehensive study of the effect of licorice on soil properties, reference sections were laid in key areas up to the groundwater table, and areas with different durations of licorice cultivation were selected. The following types of work were carried out in the field: description of the soil and soil profile, moisture content of soils and soils, selection of soil samples. Under laboratory conditions, the composition of water-soluble salts was determined. When planting licorice from the first year, a decrease in salt content is observed, by the fourth year of growing licorice, the content of dense residue ranges from 0.735 to 0.890%, by the sixth year, the soil profile to the groundwater level (GWL) turned out to be slightly saline along the profile, the content of dense residue ranges from non-saline to moderately saline degree (0.270-1.200%). With an increase in the limitation period of cultivation in the soil under licorice, the content of the chlorine ion decreases. The degree of alkalinity is strongly influenced by the content of magnesium and sodium in the soil. According to the content of total alkalinity under cultures of different age of growing licorice, there are no special differences in the profile. With an increase in the prescription of licorice cultivation, the amount of toxic salts decreases.

Climate change affects soil salinization and is responsible for food production threats and unsustainable development. However, global salinization trend and its temporal response to climate remains unclear. Here we show global soil salinization changes from 2003 to 2022 at 500 m resolution estimated by a machine learning approach, remote sensing, climate, and geographical data. Globally, soil showed a stable trend with an average trend slope value of -0.00002 ± 0.000024 dS m-1. The trend shows a large variability across the globe depending on local water regimes, and soil salinization has intensified in semi-arid and humid areas. Soil salinization trends are influenced by soil hydro-thermal conditions. Reduced terrestrial water reserves intensify salinization, and soil moisture patterns drive salinization through a three-year lag time and a three-year accumulation effect. A soil salinity change equation was proposed describing vegetation, soil moisture, climate, and topography which can be used for guiding salinization trend evaluation. Our findings reveal the global soil salinization trend and its response to climate change, providing detailed guidance for improving soil quality under different climate and hydrological conditions.

At present, the yield of cotton depends on the applied agrotechnological measures, the timing of application, the norm and type of mineral or organic fertilizers, as well as on the natural fertility of the soil, the level of crops and a number of similar measures. Maintaining and improving soil fertility is essential for sustainable agriculture. Its agrochemical properties play an important role in soil fertility. Maintaining and improving soil fertility is essential for sustainable agriculture. Its agrochemical properties play an important role in soil fertility. Cotton nutrition, growth development, yield and product quality depend on the agrochemical properties of the soil and its nutrition regime. Organic fertilizers play an important role in improving soil fertility, especially its agrochemical properties. Organic fertilizers have a complex effect on the soil and have a positive effect on the growth, development and productivity of agricultural crops, including cotton. The main substance that determines soil fertility is humus. The higher the quantity and quality of humus, the higher the yield. However, according to most scientists, the amount of humus in the soil has decreased significantly over the past 30-40 years. Organic fertilizer in fact is an effective influencing factor that improves the quality of the crop. Therefore, it is important to maintain and increase soil fertility, taking into account the properties of organic fertilizers in the soil.
