Description:
Efficient Use Of Nitrogen Fertilizer Ammonium Sulphate is the earliest nitrogen fertilizer produced and used at home and abroad. It is usually regarded as a standard nitrogen fertilizer, and the nitrogen content is between 20% and 30%. Ammonium sulfate is a strong acid and weak base salt, and its aqueous solution is acidic. Ammonium sulfate is a Chemicalbook nitrogen fertilizer and acidic fertilizer in inorganic fertilizer. Long-term single use causes soil acidification and compaction, which needs to be improved. Ammonium sulfate cannot be used to produce organic fertilizer. Moreover, acidic fertilizer can not be used with alkaline fertilizer, and double hydrolysis is easy to lose the fertilizer effect
Application:
Used for fertilizer, ammonium hydroxide, battery filling, fireproof compounds, etc

Q3: What should I pay attention to when using this product?
A: Do not contact or mix with other alkaline fertilizers or alkaline substances to avoid reducing fertilizer efficiency.
Not suitable for application on acid soil.
It is not suitable to apply ammonium sulfate on the same cultivated land for a long time, otherwise the soil will become sour and cause compaction. If it is necessary to apply, can be appropriate with some lime or organic fertilizer. However, it must be noted that ammonium sulfate cannot be mixed with lime to prevent the decomposition of nitrogen loss. Generally, the combined application of the two should be separated by 3~5 days.
