ECOLOGICAL ASSESSMENT OF SUGAR BEET GROWING TECHNOLOGY BASED ON A SET OF INDICATORS

The article is devoted to the ecological assessment of sugar beet cultivation technology by agrophysical, phytosanitary, sanitary and toxicological, biochemical, and technological indicators. The article presents an assessment of soil suitability in terms of humus, easily hydrolyzed nitrogen, mobile phosphorus, exchangeable potassium and soil reaction for obtaining high productivity of sugar beet roots with optimal biochemical and technological quality indicators. In addition, the main criteria of the indicators were methodologically substantiated, as a result of which a priority number of them were determined: climatic indicators – level of soil fertility – varietal potential of the crop – phytosanitary condition of crops – quality and safety – technological indicators – productivity of sugar beet roots. For the ecological standardization of sugar beet cultivation technology by a set of indicators, a methodological approach was developed to assess the technology for each indicator, namely 1 class – unsatisfactory condition (deviation from control for the worse exceeds 25%), II class – atisfactory (more than 10%, but not exceeding 25%); III class – normal (not exceeding 10%); IV class – optimal (no deviation from the optimum for the worse). This gradation allows to determine the ecological state of the agroecosystem by a set of indicators. In accordance with the standardization of sugar beet technology, a key conclusion is formed that reveals the assessment of technology and technological processes in order to substantiate the environmental impact of this agrotechnology on the components of the biosphere. This method of agroecological assessment of technology will provide an opportunity to obtain high-quality biochemical, technological indicators and high productivity of sugar beet and reduce the negative impact on agrocenoses.
