Abstract
A field trial compared zero grazing and grazed pasture with and without potassium (K) fertilization. Half the plots were sown with cocksfoot and the other half with tall fescue. Potassium fertilizer had an immediate effect on dry matter (DM) production. In the first year K content in the grass (especially in cocksfoot) increased from the effects of dung and urine, but five years were required to detect differences of DM production. The recycling ratio of K, variable between species and fertilization, reached fifty per cent.
