Description
Two meadows were equally fertilised and used for haymaking since their establishment in 1966. The dry matter (DM) yield decreased gradually after the establishment of the meadows and reached a stable low level around 1974, when the autumn-saved pasture (ASP) winter grazing system was introduced to one of them !ASP meadow). The productivity of the meadow for only haymaking (HM meadow) remained low (9 t/ha), whereas the productivity of the ASP meadow recovered rapidly to a high level (13 Uha). DM yield and nutrient absorption by grass in the ASP meadow (N:242, P2O5:97, K1O:412 kg/ha) were about 1.5 times as high as those in the HM meadow (N:198, P2O5:69, O:258 kg/ha). The ASP meadow had a slightly higher level of soil inorganic nitrogen (2.6 mg/100 g dry soil) than the HM meadow (2.2 mg/100 g dry soil) and the nitrification process was accelerated in the ASP meadow. The introduction of seasonal grazing promoted nutrient cycling and availability.

Continuous High Production in the Meadow by Introduction of Seasonal Grazing
Two meadows were equally fertilised and used for haymaking since their establishment in 1966.
