Mr. Xu of Xiangtan City, Hunan Province, asked whether the use of urea for rice top dressing is better than ammonium bicarbonate. Is there any difference in fertilizer effect? A: Both of these fertilizers can be used as top dressings for rice. The results are good, but ammonium bicarbonate is faster than urea. I once made a fertilizer test in paddy fields in Anhui and found that after 3 to 6 days of application of ammonium bicarbonate, the seedlings turned green and the color of rice changed only 6 to 7 days after the application of urea. This is because ammonium bicarbonate can be directly absorbed and utilized by rice after application, and urea needs to be converted into ammonium nitrogen first before it can be absorbed and utilized by crops. Therefore, in the early spring, it is better to use ammonium bicarbonate for the cultivation of topdressing because the temperature is lower, and after transplanting, the temperature is high and what kind of fertilizer is not very different.
