The application of mineral fertilizers in a single dose had an impact on the ratio of the major mineral phases. Adding a double dose of NPK resulted in a reduction of mixed-layer formations in water-peptized slugde in topsoil layer (43%). Also, in this variant of the experiment we observe an increase in the amount of hydromicas of the water-peptized sludge in topsoil by 10% compared to the control group (46% and 36%, respectively).
