    The shift of the pH of the soil solution to the acid side, which indicates the manifestation of degradation processes, is of particular concern in recent years due to climate change. After all, acid degradation intensifies the leaching of divalent cations, heavy metals in groundwater, impairs physical and chemical properties, biological activity, contributes to the fulvatization of humus, accompanied by loss of fertility and environmental degradation of surrounding areas. Effective agricultural production is possible only if the acidity of the soil solution is reduced by liming. Studies conducted by a long-term stationary experiment have shown that an alternative to traditional liming with a dose of CaCO3 calculated on hydrolytic acidity is the calculation of lime doses by pH buffering, which ensures energy conservation and maintenance of ecological stability of agroecosystems.

Key words: acidity, liming, pH-buffering, buffer capacity, fertility, fertilizers.
