Ammonium bicarbonate, abbreviated as ammonium bicarbonate, also known as heavy ammonium carbonate, has a nitrogen content of about 17%. The pure product is a white powdery crystal, and the industrial product is slightly grayish white and has an ammonia smell. Ammonium bicarbonate generally has a water content of about 5%, which is easy to deliquesce and easy to agglomerate. The temperature is relatively stable below 20 ° C, the temperature is slightly higher or the moisture in the product exceeds a certain standard, ammonium bicarbonate will be decomposed into ammonia gas and carbon dioxide, and the gas will escape in the air, resulting in nitrogen fertilizer loss. Therefore, there are six bogey using ammonium bicarbonate.
Avoid spraying foliar ammonium bicarbonate on crop leaves with strong corrosiveness, easy to burn the leaves, affecting photosynthesis, so it can not be used as foliar spray fertilizer.
Avoid applying dry soil to dry soil and applying it to the soil. The fertilizer can not be dissolved in time and absorbed by the soil and used for crops. It is only possible to dissolve in time if ammonium bicarbonate is applied with a certain humidity in the soil.
Avoid mixing ammonium bicarbonate with alkaline fertilizer. If it is mixed with alkaline ash, lime, etc., or applied at the same time, it will lose fertilizer efficiency, so ammonium bicarbonate should be applied alone.
Avoid mixing with the bacterial fertilizer and ammonium bicarbonate to emit a certain concentration of ammonia gas. If it is in contact with the bacterial fertilizer, the living bacteria in the bacterial fertilizer will die, and the effect of increasing the productivity of the bacterial fertilizer will be lost.
Do not mix with ammonium superphosphate after overnight application of ammonium bicarbonate, and it is not suitable for long-term release. It is not suitable for overnight. Because the hygroscopicity of superphosphate increases, the compost becomes slurry or agglomerate and cannot be used.
If the ammonium bicarbonate is mixed with urea and applied to the soil, the soil solution will be acidic for a short period of time, which will accelerate the volatilization loss of urea. Therefore, ammonium bicarbonate cannot be mixed with urea. (Chen Maochun, Shiyan Agricultural School, Danjiangkou City, Hubei Province)
