- A pot experiment on an acid brown soil was conducted in 1998-2001. Three multicomponent fertilizers were applied: Polifoska 8, Polifoska 15 and Polimag 306, Travit at the rates of 0.5; 1.0; and 1.5 g N per pot. The total forms of potassium were determined in dry matter of perennial ryegrass with the use of ASA method. The contents of these elements were higher in the fertilized variants as compared to the control. No significant differences were found among the contents of investigated elements compared in plants treated with different multicomponent fertilizers. The chemical analyses indicated that increasing rates of the fertilizers applied enhanced the contents of potassium. In the content of potassium in dry matter of perennial ryegrass (Lolium perenne L.) the Polifoska 8 it ranged from 3.49- 4.92 %. In the content of potassium in dry matter of perennial ryegrass (Lolium perenne L.) the Polifoska 15 it ranged from 4.29-4.86 %. In the content of potassium in dry matter of perennial ryegrass (Lolium perenne L.) the Polimag 306 it ranged from 4.07-5.17 %. In the content of potassium in dry matter of perennial ryegrass (Lolium perenne L.) the Travit it ranged from 3.84-4.73 %. The content of potassium in perennial ryegrass (Lolium perenne L.) was mostly higher on objects may receive farm manures fertilisers compared to the control object.
