NATURAL AGRICULTURAL ZONING AND AGRO-PRODUCTION GROUPING OF SOILS OF ARARAT SOIL DISTRICT OF REPUBLIC OF ARMENIA IN WRB SYSTEM

The correct natural agricultural zoning of the territory is one of the foundations promoting the improvement of the use of land resources, and therefore the general subsidence of agriculture. The scientifically grounded natural agricultural zoning can serve as a basis for the proper allocation of the branches of the farming, for the implementation of specialization, for the development and introduction of rational crop rotations and appropriate agricultural crops, for the application of advanced agricultural-technical, anti-corrosive and agro-meliorative techniques. The article deals with the issues of natural agricultural zoning of the territory of the Ararat soil district of the Republic of Armenia. The characteristics of soil fertility with the goal of the most rational study of lands in the agricultural production is given based on the existing materials on the study of the soil cover, the results of new studies and details of the natural agricultural zoning of the land fund of the given district. On the basis of comprehensive analysis and of existing materials on climate, relief, exposure, soil-forming rocks, soils and other economic and production factors, a scheme of natural-soil zoning and agro-production grouping of soils of the Ararat soil district of the RA has been developed, and the characteristics of fertility of the identified natural-soil regions and groups of soil, as well as the main ways on the increase of the productivity and fertility of lands has been presented. It is established that they can be used during the planning of agricultural and zootechnical, meliorative, agro-meliorative and soil protection arrangements envisaged for the improvement of the use and increase of productivity of the land fund of the republic.
