1. Product Overview and Basic Properties Ammonium sulfate is a widely used inorganic ammonium-based compound with the chemical formula (NH₄)₂SO₄. It contains approximately 21% nitrogen (N) and 24% sulfur (S), making it a conventional fertilizer capable of supplying two essential plant nutrients simultaneously. At room temperature, ammonium sulfate appears as white to slightly tinted crystals or granules. It is highly soluble in water, forms a mildly acidic aqueous solution, a

Urea phosphate and zinc sulfate are widely recognized as agricultural inputs used to improve crop nutrition. However, when produced to the appropriate feed-grade standard, both materials may also serve valuable functions in animal nutrition.

Nitrogen Fertilizers: A Lasting Blow to the Supply Landscape. Phosphate Fertilizers: The Sulfur Shortage Exposes a Hidden Supply Chain Crisis.

In agricultural production, people often tend to judge whether crop nutrition is sufficient simply by the amount of fertilizer applied. However, from the perspective of plant physiology, what determines crop growth and final yield is not merely the quantity of fertilizer input, but rather the balance, synergy, and utilization efficiency of nutrient elements.
