Abstract
Currently, within the framework of the program for the development of regions in Azerbaijan, it has become urgent to increase attention to the improvement of economic complexes, the protection of natural ecosystems. The solution of many national economic problems depends to a certain extent on the rational use of soil resources. Qualitative assessment of them is one of the foundations of the economic assessment of the land. The main task of the qualitative assessment of land is a comparative assessment of the degree of soil fertility and the conditions of the territory for the cultivation of various crops. The object of research is the territory of the Low-Shirvan cadastral region of Azerbaijan, a total area is 421290 hectares. To carry out the tasks of studying the soil cover, field soil studies were carried out in 2015–2018 in the study area, 53 soil cuts were put, and physical and chemical analyzes of the soil samples were carried out according to the generally accepted methods. The bonitet scale of the soils of the study area was compiled on the basis of the methods of I. I. Karmanov, D. S. Bulgakov and G. Sh. Mammadov. The main soils spread on the territory of the Low-Shirvan cadastral region are ordinary gray-meadow (18.4%); ordinary gray-brown (9.79%); alluvial meadow (8.12%); light gray-brown (8.02%); dark gray-meadow (6.69%); salines (6.05%), ordinary meadow-gray (4.97%), meadow-forest (3.97%); dark gray-brown (2.69%); marshy-meadow (2.05%); alluvial meadow-forest (1.50%); meadow gray-brown (1.22%); irrigated gray-brown (0.76%); light gray (0.47%); light meadow (0.32%) soils. After conducting a mathematical and statistical analysis of the internal diagnostic features of the soils that are widespread within the territory of the Low-Shirvan cadastral region, among them as evaluation criteria were chosen the supply of humus, nitrogen (ton/hectare) and a quantity of the absorbed bases (meq). After the evaluation work, it turned out that the most highly fertile soils of this territory were dark gray-brown soils, which we accepted as a standard - 100 points. Ordinary gray-brown and irrigated gray-brown soils turned out to be quite highly fertile, alluvial-meadow soils, which received only 50 points, turned out to be the least fertile soils of the territory.
