Agroecological potential of perennial grasses continuously cultivated in lowland peat soil

The perennial grass stand, sown in 1975 in drained lowland peat soil and used without reseeding for haymaking till today, has been annually minerally fertilised and so allows obtaining high-yielding fodders with a productivity of 5.0-5.5 thousand feed units/ha. The available agrophytocenosis support the valuable botanical composition of perennial grasses, the powerful root system of which maintains the organic soil layer.
