Ammonium sulfate (phosphate from phosphate rock), kg

Why do agronomists choose this specific nitrogen-phosphorus combination?

Granulated ammonium sulfate-phosphate, produced by OJSC PhosAgro-Cherepovets, represents a classic mineral nutrition solution that combines two vital elements in a form easily accessible to plants. Unlike simple nitrogen fertilizers that leach rapidly from the soil, the phosphorus component derived from phosphorites ensures a more prolonged release. Sulfur, included in the composition, is a critical component for protein metabolism, which is particularly essential for oilseed and cereal crops.

Key Advantages and Field Efficiency

• Optimized Nutrition: The balance of N (15-20%) and P2O5 (15-25%) meets the basic plant requirements during early developmental stages, promoting the formation of a robust root system.
• High-Tech Application: The granular form is ideal for base soil application—it is dust-free, distributes evenly across the field, and dissolves gradually into the soil solution, minimizing nutrient loss.
• Versatility: The product performs exceptionally well across a wide range of crops, including potatoes, vegetables, rapeseed, and grains, simplifying logistics for on-farm inventory.

Application Insights

This type of fertilizer is most effective when applied before plowing or cultivation. The application rate ranges from 10 to 100 kg/ha, allowing for flexible dosing based on soil analysis results. With a maximum limit of 3 applications, farmers can efficiently incorporate this product into intensive crop rotation systems.

For the grower, this solution is the 'golden mean' of cost and quality. Phosphorus from phosphorites provides sustained nutrition throughout the growing season, while nitrogen delivers the essential early 'boost.' This product is optimal for farms striving for stable yields without overcomplicating their mineral nutrition programs.
