NPK 15-5-20 — Low-Phosphorus, Potassium-Rich Dressing
Soils with years of P accumulation from repeated DAP application often test high in Olsen P while K reserves drop from continuous harvest removal. NPK 15-5-20 corrects this imbalance — 15% N, just 5% P2O5 and 20% K2O for fruit orchards, vineyards and intensive vegetable rotations on P-sufficient, K-deficient land. From 1,000 MT.

Orchard Programmes
Apple and pear orchards apply 15-5-20 at 150–250 kg/ha post-harvest to rebuild K reserves in perennial wood without adding excess P that could reduce zinc availability. Citrus receives 200–300 kg/ha split between spring flush and fruit expansion.
FAQ
When is low-P NPK like 15-5-20 the right choice?
When Olsen P exceeds 25 mg/kg and soil K tests below 120 mg/kg exchangeable K. Continuing high-P fertilization wastes money and can tie up micronutrients like Zn and Fe.
Does 15-5-20 work for banana?
Yes — banana removes large K quantities per bunch. 15-5-20 at 200 g/mat/month during bunch development supplements the low P while delivering needed K.
Can 15-5-20 be combined with micronutrient sprays?
Granular soil application of 15-5-20 complements foliar micronutrient programmes. The low P reduces soil P interference with Zn and B foliar absorption.
