Diammonium Phosphate NPK 9:25:25, AGROPOLYCHIM
Diammonium Phosphate NPK 9:25:25, AGROPOLYCHIM
NPK 9:25:25 by Agropolychim is a universal complex mineral fertilizer. Suitable for all soil types, used for pre-sowing and at-sowing application, and features a balanced ratio of essential nutrients.
Description
Diammonium Phosphate NPK 9:25:25 – a proven complex mineral fertilizer that provides crops with balanced nutrition. The composition includes 9% nitrogen, 25% phosphorus, and 25% potassium. This combination makes the fertilizer universal: it supports growth both on fertile fields and where the soil is depleted or the climate is unstable. Nitrogen is present in ammonium form, so it is absorbed gradually and does not leach out immediately. Phosphorus helps develop the root system, while potassium increases plant resilience. As a result, the crop receives everything it needs for a strong start and stable growth.
Advantages of Diammonium Phosphate (NPK 9:25:25)
- Fertilizer for autumn feeding of winter crops – plants enter winter with strong roots.
- Starter fertilizer for spring crops – uniform germination and rapid development.
- Fertilizer for the root system – a solid foundation for high yields.
- Improved winter hardiness of plants thanks to the high potassium content.
- Accelerated growth and stable development even under stress conditions.
Why choose it?
Farmers note that the use of AGROPOLYCHIM NPK 9-25-25 delivers quick results: crops look healthier, withstand temperature fluctuations, and develop better on poor soils. The fertilizer is convenient to use – granules are evenly distributed by machinery and do not cake during storage.
By choosing NPK 9-25-25, you get a Bulgarian-made product with proven quality. It is an investment in stable yields and long-term soil health.

Agropolychim NPK 9‑25‑25 – a universal compound fertilizer
Nitrogen (9%) – primarily in ammonium form, providing prolonged effect, supporting strong root establishment, and ensuring availability for plant uptake.
Phosphorus (25% P₂O₅) – a high share of water-soluble phosphorus stimulates root system development, especially important in spring and autumn.
Potassium (25% K₂O) – enhances winter hardiness, improves grain quality and overall yield.
Sulfur (1%) – an additional element that boosts nutrient efficiency.
Key Macronutrients: Total Nitrogen (N): 9%, Phosphorus (P₂O₅): 25%, Potassium (K₂O): 25%, Sulfur (S): 1%
Physical Properties: Solid granules, diameter 1–5 mm
Manufacturer: Bulgaria
The optimal nutrient ratio is especially effective for at-sowing application of spring crops.
Highly soluble granules ensure quick and even nutrient uptake by plants.
Nitrogen in two forms (ammonium and nitrate) provides consistent nutrition throughout the growing season.
Ideal for spring-start crops such as soybeans, sunflower, and vegetables — to ensure fast initial growth.
Performs best on soils with insufficient phosphorus and potassium nutrition in the autumn.
Soil preparation for winter crops — promotes strong root development, frost resistance, and a successful start.
Recommended application periods:
• Autumn — for winter crops (to support root system development and phosphorus and potassium reserves).
• Spring — for spring crops as a starter fertilizer.
Mechanical incorporation is recommended on dry soils (at plowing depth).
In areas with sufficient moisture, surface application is also possible.
Use complex solutions. Diammonium Phosphate combines nitrogen, phosphorus, and potassium, reducing the need for additional fertilization.
If the soil lacks these particular elements, the optimal solution is AGROPOLYCHIM NPK 9-25-25. The high share of phosphorus and potassium in an easily accessible form quickly corrects the imbalance and supports crop development.
For depleted soils, complex mineral blends are the most effective. Diammonium Phosphate 9:25:25 provides plants with a complete set of nutrients and ensures uniform growth even where the soil is not very fertile.
