Diamophoska N10:P20:K30+3S

Diamophoska N10:P20:K30+3S is a complex fertilizer with a high potassium content and a balanced nutrient formula, ideal for crops that are sensitive to potassium deficiency. Composition:

• Nitrogen (N) – 10%
• Phosphorus (P₂O₅) – 20%
• Potassium (K₂O) – 30%
• Sulfur (SO₃) – 3%

Potassium supports water balance, stress resistance, and sugar accumulation. Phosphorus enhances root development and energy processes. Sulfur improves nitrogen utilization and boosts protein synthesis.

Recommended use:

• for potassium-demanding crops: potatoes, sugar beets, rapeseed, sunflower, corn, vegetables, grapes, orchards;
• for base, pre-sowing, and in-row application;
• effective on chernozem, sandy loam, sod-podzolic, and gray forest soils.

Advantages:

• high potassium content – ideal for quality yields;
• balanced nutrition – enhances plant energy, stress resistance, fruit formation;
• sulfur – improves protein quality and enzymatic activity;
• granular form – precise dosing, uniform application;
• slightly acidic pH (5.5–6.5) – safe for most soils.

Limitations and warnings:

• do not mix with other fertilizers or crop protection products without prior compatibility testing;
• avoid high humidity during storage – risk of caking.

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.

Storage guarantee period: the shelf life of the fertilizer, provided that transportation and storage conditions are observed, is 12 months from the date of manufacture.
After the expiration of the guaranteed storage period, the fertilizer must be tested for compliance with technical specifications before use.

Note: It is best to fertilize all fruit and berry plants with complex fertilizers in spring, followed by soil digging. When feeding trees, it is recommended to incorporate the fertilizer into the soil at a depth of 8–10 cm.
