When applied in paddy field, the fertilizer effect was slightly lower than that of ammonium sulfate with the same amount of nitrogen, but in dry land, the fertilizer effect was similar to that of ammonium sulfate.

Calcium ammonium nitrate as a low concentration of fertilizer is a physiological neutral fertilizer, long-term application has a good effect on soil properties. It can be used as topdressing on cereal crops.
two。 Characteristics
