NPK 4-12-32 — Ultra-High Potassium for Intensive K Feeders
When soil tests confirm adequate N and P but potassium is critically depleted — common after years of harvest without K replacement — 4-12-32 delivers 32% K2O with just enough N and P to maintain basic plant function. Used in sugarcane, plantain and coconut where K removal rates exceed 300 kg K2O/ha/year. From 1,000 MT.

K Replenishment
Apply 4-12-32 at 200–300 kg/ha on K-depleted sugarcane fields after the previous crop harvest. The ultra-high K rebuilds exchangeable K reserves while minimal N avoids delaying crop ripening. Monitor soil K annually and adjust rates.
FAQ
When is 4-12-32 better than straight MOP?
When soil also needs P replenishment alongside K. 4-12-32 delivers both in one application pass, saving labour on large plantation blocks.
Can 4-12-32 cause K toxicity?
On sandy soils with low CEC, split applications of 150 kg/ha each rather than single 300 kg/ha dose to avoid luxury K uptake and potential Mg/Ca antagonism.
Is 4-12-32 suitable for coconut palms?
Yes. Mature coconut at 100–150 nuts/palm/year removes 150+ kg K2O/ha. 4-12-32 at 1.0–1.5 kg/palm/quarter maintains production on K-depleted coastal sands.
