Diammonium Phosphate N10:P26:K26+2S is a concentrated, three-component fertilizer designed specifically for crops with a high demand for phosphorus and potassium. The formula, enriched with sulfur, is ideal for:
- corn, sunflower, potatoes, legumes;
- technical crops;
- vegetables and fruit plantations.
Recommended use:
- pre-sowing application in rows or localized near the root zone;
- main application in autumn or spring;
- especially effective for crops sensitive to phosphorus and potassium deficiency, such as corn, sunflower, rapeseed, beet, potato, legumes, and fruit crops.
Advantages:
- strong starter effect — promotes rapid rooting;
- high potassium content — improves yield quality and dry matter content;
- sulfur inclusion — enhances nitrogen uptake and increases protein levels;
- safe for row application — does not cause salt stress;
- suitable for various soil types — physiologically mildly acidic (pH 5.5–6.5).
Limitations and warnings:
- not recommended for use on waterlogged or swampy soils without liming;
- avoid storage near acids, alkaline agents, or organic fertilizers.
Appearance, color: irregularly shaped granules with a characteristic odor

- store in dry, well-ventilated facilities, protected from direct sunlight, with relative air humidity not exceeding 70%. Place bags on pallets at least 15 cm above the floor, arranged in a single layer;
- packaging (bags, big bags) must be tightly sealed to prevent moisture ingress;
- permissible storage temperature: from –20 °C to +35 °C (avoid exposure to high humidity, as this may cause caking or condensation — loosen before use if necessary);
- avoid contact with acids, alkaline substances, organic compounds, or other fertilizers that may cause a chemical reaction;
- in case of prolonged storage, periodically loosen the product to prevent clumping.
Shelf life: 12 months from the date of manufacture if transportation and storage conditions are met. After the warranty period expires, the product must be tested for compliance with the technical specifications before use.
