Zalibekov Z.G., Musayev M.A., Asgerova D.B. GLOBAL SIGNIFICANCE OF TEMPORAL-FUNCTIONING PROPERTIES OF ARID SOILS AT VARIOUS DESERTIFICATION STAGES // Arid Ecosystems. 2025. Vol. 31. № 2 (103). P. 33-44. | PDF

Numerous researches of the processes of desertification and aridization in arid lands and continental deserts have established the basis for differentiating seasonal (temporal) changes that facilitate the replacement of arid soil characteristics and corresponding ecosystem components with elements of a humid regime. Sharp seasonal changes in soil and vegetation moisture are associated with differences in the atmospheric moisture availability during different periods of the year.

The natural stage of processes that help eliminate soil moisture deficits during the autumn-winter and winter-spring in the arid zone of semi-desert and steppe complexes intensifies the drying of soil profiles, enriching the roots layer with moisture in a way that is common for humid regions. The period of plants utilizing the accumulated moisture is 60-70 days, during which the ratio of air temperature and soil moisture is determined within the range optimal for plant growth and development. Identification of a period with an optimal heat/moisture ratio and of certain duration under desertification, including the highest stage of desertification, provides a reason for the development of a technology that differs from the generally accepted zonal technology and takes into account the conditions characteristic of a semi-desert climatic regime (Akimtsev, 1957; Biarslanov et al., 2021).
