Ammonium sulfate – by-product, grade A

Balanced Nitrogen and Sulfur Nutrition

Ammonium sulfate (Grade A) from OJSC Shchekinoazot is a specialized mineral fertilizer designed for high-performance crop management. With a nitrogen content of 15-20% and an essential sulfur component, it addresses the physiological needs of crops like winter wheat, soybeans, maize, and fodder beets by facilitating protein synthesis.

Technical Performance

The product’s value lies in its chemical composition, which includes trace elements such as cobalt, manganese, copper, and nickel. These elements act as catalysts for metabolic processes, enhancing nutrient uptake efficiency. Unlike nitrate-based fertilizers, the sulfate form of sulfur is highly stable in the root zone, reducing leaching and providing a steady nutrient supply throughout the vegetative stage.

Field Application Advantages

• Granulometry: The crystalline form ensures optimal flowability in mechanical spreaders, preventing segregation and ensuring uniform application across the field.
• Versatility: It is suitable for both pre-sowing soil incorporation and top-dressing, making it a flexible tool for various agronomic strategies.
• Yield Optimization: Consistent nitrogen-sulfur ratio helps plants build biomass effectively, which is vital for achieving higher protein levels in cereals and optimal oil content in legumes.

By correcting soil pH (due to its physiologically acidic nature), this fertilizer improves the availability of soil-bound minerals, contributing to overall soil health and increased yield potential.
