Agrochemical characteristics of light-gray-brown salt characteristic soils of the Kura part of Azerbaijan

Various methods of agrotechnical and reclamation measures related to soil salinization in the Kura-Araz lowland are considered. The focus is on deep plowing, which breaks the capillary channels of the soil, reduces evaporation and prevents further salinization. The need for proper soil cultivation before sowing and adaptation of sowing norms in saline areas to ensure optimal plant growth is highlighted. An integrated approach to improving soil fertility is described, including the application of organic and mineral fertilizers, as well as haymaking in the periods between irrigations. Particular emphasis is placed on the use of gypsum as a means to reduce absorbed sodium and improve soil structure, especially in areas with high salinity levels. The dosage of gypsum varies depending on the degree of soil salinity and can range from 5 to 15 t/ha. The authors emphasize that adequate water management and avoidance of over-irrigation are critical to preventing soil salinization.
