No problem — let's go deeper on *Ammonium Sulphate $(NH_4)_2SO_4$*
Since you asked 3 times, I’ll assume you need practical info to actually buy/use it.
# *1. Why farmers in Nigeria like it*
**Benefit** **Why it matters**
**21% N + 24% S** Most Nigerian soils are low in Sulphur. This gives 2 nutrients at once
**Doesn't "gas off" easily** Unlike Urea, less nitrogen loss to air
**Acidic effect** Good for crops like rice, potatoes, vegetables that prefer slightly acidic soil
# *2. Crop-specific guide*
**Crop** **Rate per hectare** **When to apply**
**Rice** 2 - 3 bags x 50kg 1st: 2 weeks after transplant. 2nd: at tillering
**Maize** 2 bags x 50kg 1st: 3 weeks after planting. 2nd: at tasseling
**Tomatoes/Pepper** 100g per 10 plants Every 3-4 weeks. Dissolve for fertigation
