Sydorenko S. Agroecological properties of oak shelterbelts in the Left-bank Forest-Steppe of Ukraine.

The object of the study is shelterbelts with the participation of common oak, which grow on typical chernozems in the Left-Bank Forest-Steppe. The subject of research is bioecological and reclamation properties of shelterbelts with the participation of common oak. For the first time, for the conditions of the Left-Bank Forest-Steppe on the basis of complex modern researches was conducted: the estimation of a modern condition oak shelterbelts and their reclamation functions; reclamation indicators of shelterbelts with the participation of common oak were determined; the criteria of anthropogenic influence on sanitary condition and protective efficiency of shelterbelts with the participation of common oak on typical chernozems are revealed; scientifically substantiated agroecological range of shelterbelts taking into account their current state on chernozems typical of adjacent fields by components of the microclimate (wind speed, air temperature and humidity, soil temperature and soil moisture at different depths, etc.); a comprehensive assessment of agroecological parameters under shelterbelt tent and on near-edge sites; the biogenicity of chernozem with typical agrogenic use under the long-term impact of shelterbelts is determined. The obtained results have scientific and practical significance for solving agroforestry аnd phytomelioration problems, in particular the necessity of wider use of common oak during planning and creation of new shelterbelts on typical chernozems in Left-Bank Forest-Steppe of Ukraine.
