Beata Draszawka-Bołzan, The Influence of Multicomponent Fertilizers on the Concentration of Nitrogen in Perennial Ryegrass (Lolium perenne L.), ILCPA Volume 13, International Letters of Chemistry, Physics and Astronomy (Volume 13)
    Urbanization is the cause of many changes which is taking place in the environment, including those found in the catchment. A pot experiment on an acid brown soil was conducted in 1998-2001. Three multicomponent fertilizers were applied: Polifoska 8, Polifoska 15, Polimag 306 and Travit at the rates of 0.5; 1.0; and 1.5 gN per pot. The total forms of nitrogen 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 nitrogen.
