The dynamics of nitrate nitrogen in soil depends on climatic factors (temperature, moisture), nitrogen resorption by plants and the fertilizers application according to results obtained. The standard nitrogenous fertilizer (LAV) and slow-release nitrogenous fertilizer (MFK) with the activity index 65.64 had the most powerful influence of the nitrate content in soil. On the other hand, the low activity index limited the low nitrate content in the soil. The dynamics of nitrate nitrogen in the soil during the vegetation period was characterized by the gradual decreasing of N-NO3** (-1) from the start of winter wheat vegetation (tillering stage) to its harvest. The results proved the nitrate nitrogen migration also in condition of clayish eutric fluvisol.
