Product overview — NPK 13-10-20
Vegetable distributors and greenhouse cooperatives request NPK 13-10-20 bulk price when fruiting crops shift from vegetative to reproductive growth. This potassium-forward grade delivers 43% total nutrients with 20% K2O, 13% N and 10% P2O5 — matching the mid-season window when tomato, pepper and eggplant need K for fruit set, sizing and shelf life without excess nitrogen that drives vine growth at the expense of yield.
Importers in Turkey, Egypt, Morocco and the Gulf use 13-10-20 as a dedicated sidedress SKU alongside basal DAP or balanced NPK at planting. Standard production is MOP-based (contains chloride) — suited to chloride-tolerant vegetables and fruiting crops. For chloride-sensitive potato or tobacco, specify SOP-based production on request. The 2–4 mm granule spreads on mechanical equipment and side-dresses cleanly in drip-irrigated rows.
Request a price quote for vessel parcels from 1,000 MT with mill COA confirming N, P2O5, K2O and moisture. Compared with separate urea and MOP applications, a single 13-10-20 pass reduces labour on labour-constrained farms while keeping N moderated during the critical fruiting phase.

Loading ports & logistics — NPK 13-10-20
Bagged NPK 13-10-20 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 vegetable belts, East African horticulture corridors and Gulf greenhouse clusters that lack bulk discharge berths.
1,000 kg FIBC big-bags suit cooperative warehouse intake where pallets feed mechanical spreaders on drip-irrigated vegetable rows. Moisture below 1.5% is specified to prevent caking during humid transit; covered storage at Mediterranean discharge ports is recommended when bags sit more than two weeks before retail repack.
Typical lead time 14–28 days from contract to bagging completion. Greenhouse cooperatives often book bagged 13-10-20 ahead of mid-season fruit-set windows when sidedress labour is concentrated in narrow weather windows.
Packaging & documentation — NPK 13-10-20
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
Processing tomato and pepper exporters apply 200–300 kg/ha at first flower cluster, 15–20 cm from the plant row. Eggplant and melon programmes sidedress at similar rates during fruit set and sizing. Greenhouse vegetable cooperatives stock 13-10-20 as the mid-cycle grade in a three-stage programme: balanced basal, K-forward mid-season, optional MOP finish on chloride-tolerant blocks before harvest.
FAQ — NPK 13-10-20
Why reduce N to 13% during fruiting?
Excess nitrogen during fruit set promotes vegetative growth at the expense of fruit number and quality. 13-10-20 provides enough N to maintain leaf health without overstimulating vine growth.
Is standard 13-10-20 suitable for chloride-sensitive crops?
No — standard MOP-based production contains chloride. Specify SOP-based 13-10-20 for chloride-sensitive potato, tobacco and export-quality tomato on sensitive varieties.
Which crops are the primary fit for MOP-based 13-10-20?
Chloride-tolerant fruiting vegetables — tomato, pepper, eggplant and melon — during fruit set and sizing when K demand peaks and N should stay moderated.
