In the studies conducted in a long-term stationary experiment, it was established that organo-mineral and mineral fertilization systems on the background of liming by hydrolytic acidity increase indicators of redox potential compared to similar fertilization and liming systems by pH-buffering. However, in variants of applying doses of lime according to the pH-buffering model, redox processes are less affected by extreme weather conditions. At the same time, the character of oxidation-reduction processes is moderately and weakly reducing. The obtained results testify to the agro-ecological reasonableness and material expediency of calculating lime application doses on acidic soils of the Carpathian region using the pH-buffering model.

Keywords: acidity, liming, fertilizers, pH-buffering, redox reactions, crop rotation.
