NK 17-28 — Potassium-Heavy Top-Dress for Quality Crops
When crops enter the yield formation phase and potassium demand outpaces nitrogen, NK 17-28 provides 17% N with 28% K2O — nearly double the K per granule. At 45% total nutrients, it freight efficiently to sugar beet, grape and potato programmes where late-season K drives quality parameters. From 1,000 MT.

Quality Phase Application
Sugar beet receives NK 17-28 at 150–200 kg/ha during root sugar accumulation phase. Wine grapes get 100–150 kg/ha at veraison for berry sugar and anthocyanin development. The K-heavy ratio avoids excess N that would delay ripening.
FAQ
Why is K nearly double N in this formula?
During quality phase, K uptake rate exceeds N in most fruit and root crops. NK 17-28 matches the nutrient removal ratio in sugar beet harvest (approximately 1.5:1 K:N).
Can NK 17-28 be used on banana?
Yes, during bunch filling stage. Apply 150–200 g/mat/month when fingers are elongating. The high K improves finger length and reduces premature ripening.
Does NK 17-28 contain chloride?
Standard grade uses MOP as K source (contains chloride). Specify SOP-based NK for chloride-sensitive crops like potato and tobacco.
