Hanchuk M. Ecological assessment of the state of agroecosystems of the Eastern Podillya

The dissertation is devoted to the study of the ecological state of agroecosystems of Eastern Podillya and the scientific substantiation of ways and methods of restoration and increase of their general productivity and ecological stability, to promote the goals of sustainable development of the region. Features of formation of regional agroecosystems are described. Based on the analysis of ecological and agrochemical indicators, their compliance with the requirements of the main crops grown in the region has been established. The assessment of the current ecological condition of agroecosystems is performed and the dynamics of each of its elements is analyzed. Factors of negative influence are defined. The ecological classification of agrolandscapes of Eastern Podillya (Vinnytsia region) according to the degree of pollution by toxic substances (residues of salts of heavy metals, pesticides, radionuclides) and agroecological zoning of the region. The scientific and methodical data on agrochemical certification are generalized and the standard scheme of the ecological passport of an agrolandscape separately for arable land, perennial plantings, hayfields and pastures is developed. Ways to optimize the functioning of agroecosystems for further ecologically balanced development of Eastern Podillya have been identified.
