There was showed that applied slurry influenced on systematic increase of the soil acidity. The acidity effect of slurry was in the both studied soil layers - arrable and subarrable layer. However, there was slower and smaller extent of slurry acidity effect than mineral fertilization. With increase in hydrogen ion content in soil, there were moving of calcium and magnesium ions into soil depth. The slurry applied with these compounds influenced on their lower decrease in the soil sorption complex. In the case of calcium, there was observed higher content of its exchange forms in the dipper soil layer
