Agrosoil zoning of the land fund of Karabakh of the Republic of Azerbaijan

Abstract

Agro-soil zoning of the land fund of Karabakh was carried out on the basis of taxonomic divisions (landscape-natural zone, agro-soil region and soil sub-district). When establishing taxonomic units, preference is given to the characteristics and properties of soils and territories acquired in the process of human economic activity. Soil subregions are identified as small taxonomic units that determine the agricultural value of soils. Among the characteristics of the territory that are important for agro-soil zoning, the conditions of micro- and nanorelief, surface slope, territory planning, drainage conditions, average annual number of microorganisms, etc. are taken into account. Within Karabakh, 3 landscape zones were identified, characterized by the predominance of the main zonal soil type: А- semi-arid subtropical low-mountain forest-shrub (mountain-meadow, mountain-meadow-steppe, mountain-forest brown); B - arid subtropical dry steppe submountain-sloping-plain (mountain-forest brown, cultivated mountain-forest brown, cultivated mountain chernozem, mountain-gray-brown, cultivated mountain-gray-brown, irrigated mountain gray-brown); V - dry subtropical semi-desert low-plain (gray soil, gray soil-meadow, irrigated meadow-gray soil, irrigated alluvial-meadow, meadow-swamp, swamp, salt marshes).
