Ammonium Sulfate (GOST 9097-82)

Balanced Nutrient Synergy: The Role of Nitrogen and Sulfur

Ammonium sulfate produced by VAT Azot (Cherkasy, Ukraine) is a high-grade mineral fertilizer manufactured in strict accordance with GOST 9097-82. In professional agriculture, this crystalline fertilizer is recognized for its unique ability to provide stable, long-lasting nitrogen coupled with essential sulfur, which is vital for the physiological development of intensive field crops.

Technical Composition and Performance

The product's efficacy lies in its chemical stability and bioavailability:

• Nitrogen (15-20%): Exists in the ammonium form (NH4+). Unlike nitrate forms, ammonium nitrogen binds effectively to soil particles, preventing excessive leaching during heavy rains and ensuring a steady supply of nutrients throughout the crop growth cycle.
• Sulfur (S): Acts as a metabolic booster. Sulfur is a fundamental building block for amino acid and protein synthesis, which is critical for maximizing both yield and the quality parameters of sunflowers, sugar beets, and cereals.

The crystalline formulation allows for precise application machinery settings, ensuring an even distribution across the field. When used as a primary fertilizer, it anchors well in the soil complex, creating a reliable nutrient reservoir for overwintering crops like winter wheat and barley, as well as for spring row crops like corn.

Practical Application

Applying the Cherkasy-manufactured ammonium sulfate is particularly beneficial for alkaline soil types. Its acidic reaction helps modulate soil pH at the root zone, facilitating better uptake of other micronutrients. The product is categorized as a low-hazard (class 4) material, making it safer and easier to handle in bulk. By optimizing the nitrogen-to-sulfur ratio, this fertilizer promotes vigorous early-stage vegetative growth and improves stress resistance in crops, directly translating to higher final yields and superior crop quality.
