Greenhouse experiments showed that in light-gray forest soil and leached chernozem, the nitrate form is most important in utilization of fertilizer N by plants, and the ammonia form in stabilization of soil. The quantity of N utilized by plants depends on the dose of N fertilizer. Introduction of N fertilizer facilitates supplementary mobilization of soil N and correlates directly with the doses of N fertilizer introduced and with its uptake by plants.
