NK 13-13 — Phosphorus-Free Nitrogen & Potassium
On soils with adequate phosphorus reserves, paying for P in every fertilizer application adds unnecessary cost. NK 13-13 delivers equal 13% N and 13% K2O without phosphorus — ideal for top-dress programmes on P-sufficient wheat, pasture and sugarcane fields. From 1,000 MT.

Top-Dress Application
Apply 150–250 kg/ha at stem elongation on winter wheat when soil Olsen P exceeds 20 mg/kg. Pasture top-dress uses 100–150 kg/ha after grazing recovery. The NK combination supports protein synthesis (N) and drought tolerance (K) simultaneously.
FAQ
Why omit phosphorus from NK fertilizer?
P is immobile in soil and accumulates with repeated DAP/MAP application. Once soil P reaches adequate levels, continuing P inputs provides no yield benefit and increases environmental runoff risk.
Can NK 13-13 replace urea + MOP separately?
Yes, with better nutrient distribution uniformity. Each granule contains both N and K at the same point, versus separate spreading passes that create uneven nutrient patches.
Is NK 13-13 suitable for rice?
For mid-season top-dress at panicle initiation, yes. Ensure soil P is adequate before relying solely on NK — rice at establishment still benefits from P if soil tests are low.
