Ideal for alkaline and neutral soils, as its acidic nature helps regulate soil pH, improving nutrient availability for crops like wheat, corn, rice, fruits, and vegetables.

High Purity:
Agricultural-grade ammonium sulfate with minimal impurities (≤0.005% heavy metals) ensures safety for food crops and compliance with international standards (ISO, SGS certified).

Turf & Landscaping: Maintains lush greenery in golf courses, parks, and lawns with controlled nutrient release.
