Summary. The territory of Azerbaijan Republic is 8641.500 hectares, of which 4227.000 hectares of the total area are utilized in agriculture. The total sown area is 1454.000 hectares. The main reason is the underestimation of the natural resources of dry and arid subtropical areas. Determination of boundaries and internal territorial units of the subtropical climate is carried out in two ways. The particular subtropical zone’s boundary is set at -12°C and the transition zone’s boundary is set at -16°C by using the average annual absolute minimum air temperature. According to D.I.Shashko, an isoline with annual humidity index of Md = 0.25 is taken as the boundary of the arid zone. The upper boundary of arid zone corresponds to the boundary of the forest zone in the mountainous area and the lower boundary corresponds to the forest-steppe zone. The boundaries of arid areas within the subtropical zone are covered by Md=0.25. It should also be noted that the -12°C isothermal line is not justifying itself when defining subtropical boundaries. In the territory of Azerbaijan there are regions where at -12°C the sum of active temperature is less than 3800°C, sometimes 3400°C. The agroclimatic zoning of arid subtropics of the Azerbaijan Republic was conducted, resulting in 1 country, 4 provinces, 3 subprovinces, 19 regions.

Keywords: subtropic, arid, agroclimate, climate, zoning
