CRITERIA FOR ASSESSING THE SUITABILITY OF THE TERRITORY FOR GRAPE CULTURE
In the article is considered the issue of criteria-based assessment of the suitability of the agricultural territories for grape culture. Conducting zoning of the territory for the purpose of rational environmental management requires an objective and comprehensive assessment of the state of agricultural territories. The complexity and novelty of it lies in the weak development of the scientific and conceptual base of the agroecology of ampelocenoses and the lack of practical experience in different natural and territorial conditions. Since there is no single integral indicator for assessing the agricultural territory in nature, the evaluation criteria are a number of bioindication, spatial and dynamic indicators, and the integral assessment is carried out on the basis of a certain number of the most influential indicators. It is known that the fundamental criterion for the assessment and zoning of agricultural territories is the compliance of edaphoclimatic factors with the requirements of the biological characteristics of cultivated varieties. Another criterion for the assessment and zoning of agricultural territories is based on the principle of the limiting factor, based on the Laws of the Liebig minimum and the Shelford ecological optimum (tolerance). The criteria limiting the development of grapes on the territory of the Krasnodar region are established, their parameters are determined. Maps of the distribution of heat supply and absolute minimum temperature are compiled, on the basis of which, taking into account soil characteristics, agricultural territories with relatively homogeneous parameters (47 subzones) are identified. The placement of grape varieties taking into account the criteria and parameters of the selected subzones can give such expected effects as increasing the efficiency of the use of edaphoclimatic resources in the production process of grapes; increasing the productivity of plantings; improving product quality; extending the productive life of plantings; reducing the cost of viticulture products; increasing the competitiveness of domestic viticulture.
