Improvement of the agrolandhaft structure due to the cultivation of perennial grasses on eroded soil

As it is known, natural steps are not just a value of forage production. Most of them occupying an intermediate position between arable land and water areas and the especially dense branch network, they have a high conservation role in agricultural landscapes: they protect the soil from erosion, the riverbanks of the rivers from clogging and channel destruction. However, forests also serve as a second powerful natural bio filter surface factor of water and soil, in fact, they form the quantity and quality of water resources in Ukraine. The purpose of the paper is to highlight the phytocenotic agricultural ecological bases and the agrotechnical basis for the formation of high productivity grass mixtures, their fertilization and their management
