Abstract: The purpose of the study was to investigate a long-term effect of mineral fertilizaation and manner of soil utilization (fallow vs. 4-course rotation) on soil properties and leaching of cations in a lysimeter experiment involving a sandy soil, a loess soil, and a loamy soil.The amount of leached Ca, Mg, and K cations depended primarily on soil kind and soil utilization.The losses of calcium and potassium were greatest on the sandy soil, the smalest calcium losses were recorded on the loess soil.After 12 years a significant increase of soil acidification, proportional to pH reduction, was recorded in non-limed and followed treatments that coincided with the appearance of mobile Al.Mineral fertilization and leaving the soils uncropped caused a significant decrease in the degree of their base saturation(V), mainly with calcium.Those adverse changes in soil properties depended both on soil kinds and starting soil pH. Liming effectively counteracted the acidification of soils fertilized with NPK.
