Abstract: The experiment was conducted to comparatively study the accumulation of multi-element long-acting granular ammonium bicarbonate and urea in the water and soil. The results showed that the accumulation of ammonium nitrogen,nitrate nitrogen and amide nitrogen of the two fertilizes increase with the increase of incubation time in the same temperature. However, the accumulation of ammonium nitrogen of the long-acting ammonium bicarbonate was lower than the urea. So the multi-element long-acting granular ammonium bicarbonate expressed the slow-release effect. In addition, the experimental result of thermostatic cultivation leaching of the two fertilizes applied in soil showed that the leaching rate of accumulation of ammonium nitrogen, nitric nitrogen and amidonitrogen was reduced
