General characteristics
Sulphoammophos N20:P20+15S is a concentrated nitrogen-phosphorus fertilizer with a high sulfur content in the form of sulfate (SO₃), which is readily available to plants. This combination is especially beneficial for crops with elevated needs for nitrogen, phosphorus, and sulfur, such as rapeseed, cereals, corn, legumes, oilseeds, and vegetables. The N:P ratio of 1:1 makes this fertilizer ideal for starter applications, when plants require balanced nutrient intake to support root development, photosynthesis, and reproductive growth.Sulfur:
- enhances nitrogen uptake;
- stimulates protein and enzyme metabolism;
- increases levels of protein, oil, gluten, and amino acids in crops.
Recommended use
- for primary soil treatment in autumn or spring;
- pre-sowing application;
- in-furrow placement during seeding;
- especially effective on sod-podzolic, sierozem, chernozem, sandy loam, and light soils.
Advantages
- even nutrient release — balanced supply of N and P;
- sulfur boosts nitrogen efficiency;
- suitable for all crops, especially those sensitive to sulfur deficiency (rapeseed, legumes, sunflower, onion, garlic, cruciferous crops);
- enhances product quality: protein in cereals, oil content in rapeseed, sugar in vegetables;
- physiologically neutral (pH 5.5–6.5) — does not acidify soil;
- convenient granule form — easy dosing and uniform application.
Limitations & precautions
- Do not mix with alkaline or organic fertilizers without a compatibility test;
- Avoid application on waterlogged soils without drainage or liming.
Appearance and сolor: 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.
