In microfield stationary experiments conducted during 8 years utilization of nitrogen of labeled 15N ammonium saltpeter by winter wheat with different doses and dates of application (tillering phase and fractionally) and the balance of this element were studied. It has been found that the structure of nitrogen balance varies widely with the extent of cultivation of soddy-podzolic soil, the dose and the date of applying the fertilizer.
