Ammonium Sulfate

Effective nitrogen and sulfur: experience with Polimir ammonium sulfate

When planning fertilizer applications for winter crops or potatoes, we often choose ammonium sulfate from JSC Naftan, Polimir plant (Republic of Belarus) due to its reliability. It is a classic crystalline product that consistently performs well in our soils. It is convenient to handle: the crystals do not dust excessively, which is critical when loading spreaders, and with the right equipment settings, it is distributed evenly across the field.

When working with this fertilizer, it is worth considering its physical properties. Since it is a Hazard Class 3 substance, we strictly follow agrochemical safety protocols: we use personal protective equipment and control humidity in the storage area, as the crystalline form is sensitive to caking if storage conditions are violated. In the field, it is important to follow the main application schedule—the fertilizer works best when incorporated into the soil before sowing, providing complete nutrition for crops during the early stages of vegetation.

Agronomic benefits and dosage

Why do we choose this particular option? The combination of nitrogen (20-25%) and sulfur provides a complex effect. Nitrogen triggers the growth of vegetative mass, while sulfur is critically necessary for protein metabolism, especially in rapeseed, cereals, and vegetable crops. We note that with regular use of this composition on cereals, not only does overall yield increase, but so do grain quality indicators. Potatoes and beets also respond to sulfur fertilization with a significant increase in tubers and root crops.

• Easy logistics: Convenience of transporting and storing the crystalline form.
• Stable nutrition: Nitrogen in the ammonium form leaches from the soil less than nitrate analogs.
• Versatility: Suitable for almost all major crops: from rice to fruit and berry plantations.

In intensive farming conditions, this product serves as a foundation, allowing control over plant nutrition at the most critical stages. When calculating rates, it is important to rely on soil analysis data, but as an agronomic tool, Belarusian ammonium sulfate remains a reliable and economically justified solution.
