Streszczenie:
In this paper, the analysis of variance of the results of experiment conducted in laboratory conditions is described. The objective of this study was to evaluate changes in soil reaction, hydrolytic acidity, sum of bases and available potassium and magnesium in sandy soil incubated with two doses of composted sewage sludge (30 and 120 Mg per hectare) over period of 180 days. The data obtained showed that with regard to the unamended soil, both the 30 and 120 Mg per hectare treatments similarly influenced on analyzed properties but the effect was more visible at the case of the higher compost dose. Additionally it was found, that compost prepared on the basis of sewage sludge is an important source of potassium and magnesium. During incubation process the patterns of changes of hydrolytic acidity and available potassium and magnesium were different for particular treatments
