The paper examined the effects of lime application at the rate of 3 t/ha on pseudogley soil agrochemical changes and alfalfa yield during a two-year period. The applied lime in combination with mineral fertilizers significantly decreased acidity in H2O (by 0.6 pH units) and in nKCl (by 0.81 pH units). At the same time, there was increase in phosphorus availability and soil base saturation percentage in the 0-30 cm arable horizon. The performed liming intensified organic matter mineralization, which caused decrease of humus content as well as of mobile Al and Fe content compared to control. Moderate liming improved pseudogley agrochemical properties, which was manifested by increased alfalfa yield.
