FAQ

Q1: How does this product benefit crops?
A: This product is suitable for a wide range of soils and crops. It promotes robust branch and leaf growth, improves fruit quality and yield, and enhances crop resilience against disasters.

Q2: What are the recommended applications of this fertilizer for crops?
A: Ammonium Sulphate Granular Nitrogen Fertilizer Agriculture Grade can be used as a base fertilizer, topdressing fertilizer, and seed fertilizer.

Q3: What precautions should be taken when using this product?
A: Avoid contact or mixing with alkaline fertilizers or substances to prevent a reduction in fertilizer efficiency. It is not suitable for application on acidic soil. Long-term application of ammonium sulfate on the same cultivated land may acidify the soil and cause compaction. If necessary, it can be used in conjunction with lime or organic fertilizer. However, note that ammonium sulfate should not be mixed with lime to prevent nitrogen loss due to decomposition. Ideally, the combined application of the two should be spaced 3-5 days apart.
