Product overview — NPK 4-12-32
Plantation managers and sugarcane cooperatives request NPK 4-12-32 bulk price when soil tests confirm critically depleted exchangeable K after years of harvest without K replacement, while moderate P continues to leave the field with each crop. This ultra-high K grade delivers 48% total nutrients with 32% K2O, 12% P2O5 and just 4% N — rebuilding K reserves and supplying maintenance P in one pass while minimal N avoids delaying ripening on intensive K feeders.
Importers in Southeast Asia, West Africa and the Caribbean use 4-12-32 for sugarcane, plantain and coconut where K removal rates exceed 300 kg K2O/ha/year. Mature coconut at 100–150 nuts/palm/year receives 1.0–1.5 kg/palm/quarter on K-depleted coastal sands. The 2–4 mm granule broadcasts on plantation blocks or applies in split doses on sandy soils with low CEC.
Request a price quote for vessel parcels from 1,000 MT with mill COA. When both K rebuild and maintenance P are needed in the same application window, 4-12-32 covers both nutrients — saving labour on large plantation blocks compared with separate MOP and phosphate applications.

Loading ports & logistics — NPK 4-12-32
Ultra-high K grade at 48% total nutrients — contract MOQ 1,000 MT ships as 50 kg PP bags or 1,000 kg FIBC in containers, or on coaster parcels from 1,000 MT to plantation buyers without bulk discharge. Typical bulk compound movements use geared bulkers from 3,000 MT up to 20,000 MT handysize parcels on Novorossiysk and Baltic corridor terminals; discharge to Southeast Asian plantation belts, West African sugarcane regions and Caribbean coconut estates.
Loading rates reach 4,000–8,000 MT per day at dedicated fertilizer berths. Humid tropical warehousing demands moisture control below 1.5% — covered storage at discharge is essential for bulk lots in high-rainfall ports before quarterly palm or ratoon field application.
Contract lead time typically 10–20 days from payment instrument confirmation to first laycan window. Sugarcane cooperatives often nominate 4-12-32 bulk for post-harvest laycan windows when K rebuild must coincide with ratoon stubble recovery.
Packaging & documentation — NPK 4-12-32
Bulk hold shipment with moisture barrier tarps, or 50 kg bags palletised for manual plantation application, or 1,000 kg FIBC for estate direct purchase. Each lot includes mill certificate of analysis, commercial invoice, packing list, bill of lading and certificate of origin. SGS or Bureau Veritas inspection at loading available for LC-backed contracts.
Buyer segments & crop programmes
Sugarcane fields apply 200–300 kg/ha after previous crop harvest to rebuild K reserves. Coconut palms receive 1.0–1.5 kg/palm/quarter. On sandy soils with low CEC, split applications of 150 kg/ha each rather than single 300 kg/ha doses avoid luxury K uptake and potential Mg/Ca antagonism.
FAQ — NPK 4-12-32
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.
