The Role Of Perennial Grasses In The Protection Of Soil Resources Of Erosive Ecosystems With Active Development Of Linear Erosion

Abstract We evaluated the stability of perennial legume and cereal grass species in artificial plant communities on permanent anti-erosion watercourses agroecosystems Belgorod region with active development linear soil erosion. In conditions steppe forest-steppe zones permanently grassed 2017-2019. varieties leguminous grasses: ‘Krasnoyaruzhskaya 1’ 2’ ( Medicago varia ), ‘Kazatsky’ Trifolium pratense ‘Olshanka’ ‘Ivica’ Festuca arundinacea ) , ‘ Streletsky’ ‘Stepnyak’ Lolium perenne )) obtained using local genetic material were studied. All showed their resistance agro-ecosystems erosion zones. Projective cover zone all variants experience was average 83,4 %, - 86,3 %. third year tests irrigated zone, share quite high varied from 88 % variant M. + Onobrychis arenaria to 92 Bromopsis inermis O. arenaria. 86 L. 94 B. inermis.
