Q1: Is this product safe for long-term use?
A: Yes, this product is completely free from any harmful substances and can be used safely for extended periods of time.

Q2: What are some things I need to know when using this product?
A: Our organic nitrogen fertilizer is made from urea, which is hydrolyzed into ammonium carbonate or ammonium bicarbonate by the soil urease. This chemical reaction allows crops to absorb the nutrients they need. To ensure optimal results, urea should be applied between 4 and 8 days before crop fertilization. Please note that urea cannot be used as a seed fertilizer, seedling fertilizer, or leaf fertilizer. When applied to the surface, urea can cause volatilization, especially on alkaline soil. To avoid this, users should apply urea deep into the soil or apply it deep to the reducing layer in paddy fields.
