THE EFFECTIVENESS OF THE USE OF PERENNIAL GRASSES IN SOLVING THE PROBLEM OF BIOLOGIZATION OF AGRICULTURE IN THE REPUBLIC OF KARELIA

One of approaches to biologization of agriculture in Karelia is a widespread use of perennial grasses, which are a source of fodder and perform important ecological functions. We compared yield and protein productivity (tons/hectare) of one- and three-species grass stands including foxtail clover Tr...
