Applications & Benefits
Agricultural Use
-
Nitrogen Supply: Provides readily available ammoniacal nitrogen for immediate uptake by crops, promoting vigorous vegetative growth, deep green foliage, and robust stem development.
-
Sulfur Enrichment: Supplies 24% sulfate-sulfur, correcting sulfur deficiencies in soils and enhancing protein synthesis, oil content, and enzyme activation in plants.
-
Soil Acidification: Ideal for alkaline soils; the nitrification process gently lowers soil pH, improving micronutrient availability (Fe, Mn, Zn) for acid-loving crops such as blueberries, tea, and potatoes.
-
Crop Compatibility: Suitable for cereals, oilseeds, vegetables, fruits, turf, and forage crops.
Fertilizer Program Integration
-
Basal Fertilizer: Apply before sowing or transplanting to build foundational nutrient reserves.
-
Top Dressing: Side-dress or broadcast during active growth stages for quick nitrogen replenishment.
-
Seed Fertilizer: Used in starter formulations at controlled rates to support early root establishment without salt injury.
Industrial Applications
-
Flame Retardant Additive: Used in textile and wood processing.
-
Food & Pharmaceutical Grade: Purified grades serve as buffering agents and yeast nutrients in fermentation processes.
-
Water Treatment: Component in precipitation and pH adjustment systems.
Handling, Safety & Regulatory
-
Hazard Classification: Non-flammable solid. Low toxicity under normal handling conditions.
-
Personal Protective Equipment: Safety goggles, dust mask, and gloves recommended during prolonged exposure or in dusty environments.
-
First Aid: In case of eye contact, rinse thoroughly with water. If ingested, seek medical attention.
-
Environmental Considerations: Prevent runoff into waterways. Ammonium sulfate is biodegradable and non-persistent in the environment when applied according to agronomic recommendations.
-
Regulatory Status: Compliant with FAO/WHO fertilizer quality standards and REACH regulations (where applicable).
