ABSTRACT

The paper presents the results of a pot experiment on phosphatase activity and ATP level in plant and in soil induced by diversified doses of copper (II) nitrate (V). Five combinations of copper (II) salt were applied; each combination was conducted in 4 identical series. Water solutions of copper (II) nitrate (V) were introduced into 5 soil samples in the following doses: no salt introduced (control), 0.05 mmol^. kg^-1, 0.50 mmol·kg^-1, 5.00 mmol·kg^-1, 50.00 mmol^.kg^-1 of soil for the samples from 1 to 5, respectively. Size grading of the soil experimented was typical for light silty clay. Sown Pea /Pisum sativum L./ of Amethyst variety served as a test plant. Enzymes activities and ATP contents in both soil and plant samples were analysed in various developmental stages of Sown Pea, namely at the two-leaves, blooming and green legume stages. Copper (II) nitrate (V) introduced into soil (apart from 0.0
