Product overview — NPK 15-5-20

Orchard distributors and vineyard cooperatives request NPK 15-5-20 bulk price when soils test high in Olsen P but depleted in exchangeable K after years of DAP use and continuous harvest removal. This low-phosphorus grade delivers 40% total nutrients with 20% K2O, 15% N and just 5% P2O5 — correcting the P/K imbalance common on mature fruit blocks without adding excess phosphorus that ties up zinc and iron.

Importers in Turkey, Chile, South Africa and the Mediterranean use 15-5-20 as a post-harvest and mid-season dressing SKU for apple, pear, citrus and banana programmes. Intensive vegetable rotations on P-sufficient greenhouse soils apply it between cash crops to rebuild K without overloading P. The 2–4 mm granule spreads under tree canopies and band-applies in vineyard rows.

Request a price quote for vessel parcels from 1,000 MT with mill COA confirming N, P2O5, K2O and moisture. Compared with balanced 15-15-15 on P-adequate soils, 15-5-20 avoids wasteful P application while delivering the K fraction fruit crops need for sizing, colour and storage quality.

Loading ports & logistics — NPK 15-5-20

Bagged NPK 15-5-20 ships in 50 kg PP woven bags with PE liner — minimum order 1,000 MT for dedicated bagging runs at Black Sea and MENA granulation terminals. FOB terms at load ports; CFR/CIF to Mediterranean orchard belts, South American fruit export corridors and Gulf greenhouse clusters.

1,000 kg FIBC big-bags suit cooperative warehouse intake where pallets feed mechanical spreaders under tree canopies. Moisture below 1.5% is specified to prevent caking during humid transit; covered storage at Mediterranean discharge ports is recommended when bags await post-harvest orchard application windows.

Typical lead time 14–28 days from contract to bagging completion. Orchard distributors often book bagged 15-5-20 for post-harvest windows when fruit blocks need K without excess P on Olsen-P-adequate soils.

Packaging & documentation — NPK 15-5-20

Bulk hold shipment with moisture barrier tarps, or 50 kg bags palletised for retail repack, or 1,000 kg FIBC for cooperative 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

Apple and pear orchards apply 150–250 kg/ha post-harvest to rebuild K reserves in perennial wood without adding excess P. Citrus receives 200–300 kg/ha split between spring flush and fruit expansion. Banana mats take 200 g/mat/month during bunch development — the low P supplements while delivering needed K.

FAQ — NPK 15-5-20

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.
