Object of study – interdependence between toxic-ecological characteristics of the main production of agrocenoses, different levels of chemicalisation of agriculture and the state of individual agro-ecosystems of the forest-steppe right-bank.
The aim of the study – to carry out ecological assessment and substantiate the principles of regulation of toxic-ecological safety of the basic production of agrocenoses at different levels of chemicalisation of agriculture in the conditions of the Forest-steppe of the right-bank.
Research methods – general scientific (analysis, experiment, observation, hypotheses, induction, deduction) – for choosing directions of research and processing of actual material; special – field (study of the interaction of the object with anthropic factors; accounting for the productivity of agrocenoses); chemical - determination of agrochemical properties and content of elements in soil, the main production of agrocenoses; statistical – establishing, based on correlation-regression analysis, the reliability of the results obtained and the relationships between the various factors and consequences.
Theoretical and practical results – for the agro-ecosystems of the forest-steppe of the right bank, resource-saving elements of technology of cultivation of crops and ways of normalization of the content of pollutants in seeds of agrocenoses during storage and processing by toxic-ecological criteria are recommended.
Novelty – for the first time on the example of the right-bank forest-steppe agro-ecosystems the quality assessment of the main production of agrocenoses by toxic-ecological indicators was conducted depending on abiotic and anthropic factors, including levels of intensity of chemistry of agriculture; the possibility of normalization of the content of pollutants in seeds of crops of agrocenoses to the limits of MPC with the resource-saving chemization of agriculture is proved.
The degree of implementation – the results of the study were implemented in PE "ZETO", v. Murafa during storage of winter wheat grain volume of 150 t, spring barley grain – 110 t, winter rapeseed seeds – 130 t; PE " Strilets ", v. Strilnyky during storage of winter wheat grain volume of 140 t, spring barley grain – 108 t, winter rapeseed seeds – 125 t, PE "Kolos-Lan", p. Bolgan when storing 110 tonnes of winter wheat, 125 tonnes of spring barley, 100 tonnes of winter rapeseed, and the Uladovo-Liulynetsku Research and Breeding Station of the Institute of Bioenergy Crops and Sugar Beets of the National Academy of Sciences of Ukraine, pv. Uladivske when storing winter wheat with a volume of 120 t, spring barley grain – 100 t, winter rape seeds – 120 t.
Scope (area) of use – growing of cereals (except rice), legumes and oilseeds.
