Product overview — NK 21-21
NK 21-21 price per ton suits intensive top-dress on high-yield wheat, maize and cotton where both N and K must be replenished mid-season without adding phosphorus. At 21% N and 21% K2O, this is among the highest-analysis NK compounds available — delivering 42% total nutrients per application pass.
Irrigated wheat at flag leaf emergence receives 150–200 kg/ha, delivering 30–40 kg N and K each. High-yield cotton at peak boll load uses 200–250 kg/ha. Sugarcane grand growth phase applies 200–250 kg/ha when cane height reaches 1.2–1.5 m.
Split application improves N recovery on sandy soils: two passes of 100 kg/ha at stem extension and flag leaf versus a single large dose. HS code 3105.20. From 1,000 MT.

Loading ports & logistics — NK 21-21
NK 21-21 for inland buyers ships in 1,000 kg FIBC big-bags or 20–24 MT container lots where high-yield wheat cooperatives lack bulk discharge berths. Coastal feeder parcels run 1,000–5,000 MT on coaster tonnage from Black Sea and MENA load terminals.
Container and FIBC deliveries serve landlocked distributors and regional blending plants without berth draft for handysize carriers. 50 kg bags available when cooperative retail networks need repack from inland warehouses.
Lead time 14–30 days depending on container availability and feeder line scheduling. High-yield wheat cooperatives often split NK 21-21 delivery across two FIBC consignments for stem extension and flag-leaf passes.
Packaging & documentation — NK 21-21
Each lot ships with a mill certificate of analysis. Standard document set: commercial invoice, packing list (bagged lots), bill of lading, certificate of origin and phytosanitary certificate where required. Third-party inspection at loading can be arranged on buyer request.
Payment terms: irrevocable LC at sight or CAD for first-time buyers; established accounts may negotiate open-account structures.
FAQ — NK 21-21
When is NK 21-21 preferred over NK 15-15?
On high-yield potential fields where mid-season N and K demand exceeds what 15-15 can supply without excessive application bulk.
Can NK 21-21 be split-applied?
Yes. Two applications of 100 kg/ha each at stem extension and flag leaf improve N recovery compared to a single large dose, especially on sandy soils prone to leaching.
Is NK 21-21 suitable for sugarcane?
For grand growth phase, yes. Apply 200–250 kg/ha when cane height reaches 1.2–1.5 m. The equal N:K ratio supports stalk elongation and sucrose accumulation.
