Possibilities of reducing the phytotoxic effect of nickel
Journal Title: Acta Agrophysica - Year 2018, Vol 25, Issue 3
Abstract
A pot experiment was conducted in the years 2009-2010. Its aim was to determine the limit of toxicity of nickel to orchard grass (<i>Dactylis glomerata</i> L.) and methods of its reduction by liming and by the addition of straw or brown coal to soil. The addition of nickel to soil, regardless of its dose, increased its content in the test plant and in soil, especially in fraction F<sub>1</sub>. The content of nickel in biomass of orchard grass exceeded the limit values in pots where it was added to soil. Soil liming reduced the content of nickel in orchard grass and in fractions isolated from soil – soluble fraction F<sub>1</sub>, reducible fraction F<sub>2</sub> and oxidisable fraction F<sub>3</sub>. The addition of rye straw and brown coal to the soil reduced the content of nickel in the test grass and the content in bioavailable fraction F<sub>1</sub>. Liming and the addition of rye straw and brown coal to soil reduced the phytoavailability of nickel.
