Q1: What does this product do to the crop?
A: It's suitable for general soil and crops, can make branches and leaves grow vigorously, improve fruit quality and yield, enhance crop resistance to disasters.
Q2: What kind of fertilizer is this suitable for use as a crop fertilizer?
A: Ammonium sulfate can be used as base fertilizer, topdressing fertilizer and seed fertilizer.
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.
