NPK
NPK is a combination of nitrogen (N), phosphorus (P) and potassium (K) designed to maximize crop yield and quality.
NPK 15-15-15 is one of the most highly efficient sources of N, P and K available.
| Qualitative characteristics | NPK 15-15-15 | |
|---|---|---|
| Total Nitrogen, %, max | 15 ± 1 | |
| Ammonium Nitrogen (NH4), % | 9 | |
| Nitric Nitrogen, % | 6 | |
| Total Assimilable phosphates in terms of P2O5, % | 15 ± 1 | |
| Water-soluble phosphates in terms of P2O5, %, min | 10 | |
| Potassium in terms of K2O, % | 15 ± 1 | |
| Water content, %, max | 1.2 | |
| Granulometric composition: | ||
| - under 1 mm, %, max | 3 | |
| - 1 - 6 mm, % | 97 | |
| - below than 6 mm, % | 100 | |
| Static strength of granules, MPa (kg.f/cm2), min | 3 (30) | |
| Friability, % | 100 | |
| Sulphur, % | 2 | |
NPK is a complex universal fertilizer for any soils and crops, most effective when applied for tilled and technical crops – before pre-sowing cultivation or during sowing. It is also a perfect starter fertilizer for spring cereals.
The sulphur content ensures high intake of nitrogen and phosphorus by plants, and potassium facilitates faster transport of synthesis products (carbohydrates) to root vegetables and seeds.
The product is packed in 25 kg and 50 kg laminated polypropylene bags with polyethylene liner and in 1000, 1200 and 1250 kg big-bags.
Packed NPK in bulk is stored in warehouses protecting the product from precipitation and pollution.
NPK is transported packed (in bags, containers, transport packagings) and in bulk by all means of transportation, except by air, in accordance with cargo carriage regulations applicable to a particular transportation mode.
Guaranteed storage life: 6 months from the date of manufacture.
