In 1999-2000, a stationary field experiment on Ortic Luvisol was performed to investigate the effect of different soil cultivation and harvest residues of maize on inorganic nitrogen content in soil under monoculture of maize. The weather conditions during the growing season, in the interaction with other factors and agrotechnical interventions, had the most decisive effect on a level of inorganic nitrogen in soil. Basic soil treatment had no statistically significant influence on the changes in inorganic nitrogen content. Ploughing down of crop residues of maize stalks was reflected in a slight increase of inorganic nitrogen. This rise was not statistically significant
