COMPLEX MINERAL FERTILIZER NP18:38+5S+0-0,3Zn

A Strong Start for Yield: Field Experience with «Tigos» NP 18:38

When it comes to winter wheat and cereals, mistakes in mineral nutrition at the early stage can be costly. After working for several seasons with the complex fertilizer NP 18:38+5S+0,3Zn from the Ukrainian producer «Tigos», I’ve identified several critical points that every agronomist should keep in mind.

Application Efficiency and Granulometry

The first thing I appreciate about this product is the physical quality of the granules. They are uniform, firm, do not produce dust in the planter, and do not clog the seeding mechanisms. With a dosage rate of 100–200 kg/ha, this is crucial for even distribution across the field. We use it for both basic application and top-dressing, and the result is consistently reliable: the fertilizer dissolves quickly in the soil solution, becoming accessible to the root system exactly when the plant enters its active growth phase.

Why the N-P-S-Zn Combo Works

The balance is well-calibrated: 18% nitrogen provides the necessary post-winter boost, while 38% phosphorus sets the foundation for the future ear. However, the standout feature in practice is the combination of sulfur (5%) and zinc (0,3%). Sulfur aids in nitrogen absorption and enhances the quality of gluten in the grain. Zinc acts as a metabolic catalyst, noticeably increasing the stress resistance of winter crops during temperature fluctuations—a vital necessity for our climate.

Operational Tips

• Dosage Control: I do not recommend exceeding 200 kg/ha without a thorough soil analysis. At optimal rates, the product works with maximum efficiency, ensuring cell membrane strength and improved crop durability.
• Application Frequency: Up to two applications allow for flexible nutrient management based on weather conditions.
• Safety: The fertilizer is classified as Hazard Class 4, which significantly simplifies the workload for operators—no specialized chemical suits are required, only standard safety precautions.

In short: «Tigos» provides a predictable, professional tool. It’s not a magic fix, but a reliable foundation for cereal crops that delivers results when the application technology is followed correctly.
