In the present study, the effect of the precipitate as a chemical ameliorant on the changes of the values of the pH indicator along the depth of the soil profile was studied. Its interaction with the soil was also associated with the release of Са2+, which was due to its prophylactic chemical-ameliorative effect in acidic soils. The movement of the precipitate along the depth of the soil profile and in general the migration of this compound into the soil volume was very limited, both with respect to the phosphate and the calcium component. Better penetration into the deep soil horizons was observed at constant humidity close to utmost field moisture content and at soils with a high rate of natural water filtration.
