Product Overview
High-Nitrogen NPK 20-10-10 is an ammonia-rich compound fertilizer engineered for crops with heavy nitrogen demand during vegetative growth phases. With double the nitrogen content relative to phosphorus and potassium, this formulation drives rapid canopy development, tiller production, and chlorophyll synthesis. Manufactured by Dongkwang Poland under strict ISO 9001:2015 quality standards, each granule contains a dual nitrogen source — ammonium for sustained release and nitrate for immediate uptake — ensuring uninterrupted nitrogen supply during the critical growth window. Widely deployed across European cereal belts, West African maize corridors, and South American pasture systems.
How High-Nitrogen NPK 20-10-10 Works
The elevated nitrogen content (20% N) combines ammonium-nitrogen and nitrate-nitrogen for a two-phase release profile. Nitrate-N is immediately plant-available, driving rapid green-up within 5-7 days of application. Ammonium-N adsorbs to soil colloids and converts to nitrate via nitrification over 2-4 weeks, providing sustained feeding. The supporting phosphorus (10% P₂O₅) maintains root activity for efficient nitrogen uptake, while potassium (10% K₂O) strengthens cell walls and enzyme systems to handle the accelerated growth rate without lodging or pest susceptibility.
Key Benefits
Application Guide
For cereals: apply 350-450 kg/ha at sowing or as an early spring top-dress at GS21-25 (tillering). For maize: apply 400 kg/ha at planting, followed by a 200 kg/ha side-dress at V6-V8. For pasture and forage grasses: apply 300-400 kg/ha in split applications after each grazing rotation. For leafy vegetables (lettuce, spinach, cabbage): apply 250-350 kg/ha incorporated before planting. Avoid late-season application on fruiting crops as excess nitrogen delays maturity.
Ideal For
Storage & Handling
Store in a dry, covered area on pallets. Avoid contact with oxidising agents, strong acids, and combustible materials. Maximum stack height: 3 pallets. Shelf life: 24 months in original packaging. Hygroscopic — reseal opened bags immediately to prevent caking. Wear dust mask and gloves during handling.
Why Choose Dongkwang Poland?
Dongkwang Poland’s 20-10-10 is produced using state-of-the-art granulation technology that ensures each granule is chemically homogeneous — not a physical blend. This eliminates segregation during transport and spreading, guaranteeing every square metre of your field receives the correct nutrient ratio. Our production facility holds ISO 9001:2015 certification, and every batch is accompanied by a Certificate of Analysis verifiable through our quality portal.
