Nitrogen fertilization is the most influential in terms of increasing crop production. Mineral nitrogen, except increasing the content of nitrate in soil, leads to changes in soil pH and many other soil properties. Long-term mineral nitrogen addition experiments (over 40-years) can give us valuable information about how those changes occur and point out the trends of the changes. The experiment was set up on cambisol 40 years ago with 60, 90 and 120 kg of N per ha. The results showed the significant increase in N content, humus and soil CEC, while the sum of base and base saturation decreased.
