On the basis of the results obtained the following conclusions can be drawn: 1) The activity of both acid and alkaline phosphomonoesterase in soil grown with maize depends on the NPK application rate, maize growth stage and the year in which the experiment is performed; 2) The NPK fertilizers inhibited the activity of alkaline phosphomonoesterase, while the activity of the acid phosphomonoesterase was similar to the control treatment (no fertilization); 3) Higher application rate of the NPK fertilizers (664 kg/ha) decreased the level of activity of alkaline phosphomonoesterase by approximateky 20% comparing to the control.
