Beata Draszawka-Bołzan, The Contents of Nickel in Perennial Ryegrass (Lolium perenne L.) as Affected by Application of Multicomponent Fertilizers, ILCPA Volume 12, International Letters of Chemistry, Physics and Astronomy (Volume 12)
    Urbanization is the cause of many changes which is taking place in the environment, including those found in the catchment. Three multicomponent fertilizers were applied: Polifoska 8, Polifoska 16 and Polimag 306, at the rates of 0.5; 1.0; and 1.5 g N per pot. The total forms of nickel 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 increasing rates of nitrogen decreased soil pH and, thereby, enhanced the availability and concentration of heavy metals in perennial ryegrass. A pot experiment on an acid brown soil was conducted in 1998-2001.
