On the basis of the results, the following was concluded: the mineral nitrogen dynamics in soil is closely connected to the crop increase intensity. The tested crops were: wheat, maize, sugar beet, sunflower and soy bean. In convenient years due to intensive acceptance, the content of mineral nitrogen is lower. The nitrification process was most intensive under maize and then sugarbeet. The slower nitrification is observed under soy beans. The high contents of mineral nitrogen is observed with wheat and at the end of vegetation period the negative correlation is observed between the effect of mineral nitrogen in soil and the yield.
