Product overview — NPK 12-12-17
NPK 12-12-17 is a granular compound fertilizer that keeps nitrogen and phosphorus in a balanced 1:1 ratio while shifting potassium to 17% K2O — five points above the standard 12-12-12 grade. At 41% total nutrients the formula bridges the gap between entry-level balanced NPK and high-analysis K-forward compounds, making it a workhorse for perennial horticulture where potassium removal through harvest outpaces N and P uptake.
Stone fruit orchards, table grape vineyards, blueberry fields and strawberry tunnels are the primary export destinations. Potassium drives Brix development, skin colour and cold-storage tolerance; the equal N and P fractions maintain canopy vigour and root carbohydrate reserves through dormancy and post-harvest recovery. Importers in Turkey, Egypt, India and East Africa use 12-12-17 as a single-application base dressing that reduces the need for separate MOP top-dress in moderate-K soils.
Production originates from NPK granulation lines at Black Sea and Central Asian complexes. Granules are hard, dust-free and sized 2–4 mm for mechanical spreading and bulk-blending compatibility. Chloride content is controlled through the potassium source selection, supporting use on chloride-sensitive rootstocks when soil salinity is a concern.

Loading ports & logistics — NPK 12-12-17
Potassium-enhanced balanced compound for perennial horticulture — bulk NPK 12-12-17 loads in vessel holds from 3,000 MT minimum on geared bulk carriers up to 20,000 MT handysize parcels. FOB loading at Novorossiysk, Baltic corridor terminals and Black Sea NPK complexes with covered silo storage; humid-climate transit requires moisture below 1.5% at dispatch and prompt warehouse transfer at discharge.
Loading rates reach 4,000–8,000 MT per day at modern NPK berths. CFR and CIF nominations target stone-fruit and vineyard discharge corridors — Mersin, Alexandria, Casablanca, Valencia — with handysize tonnage matched to draft limits.
Contract lead time 12–25 days from payment instrument confirmation to first laycan day.
Packaging & documentation — NPK 12-12-17
Bulk: free-flowing granular loaded directly into vessel holds with trimming to stowage plan. Bagged: 50 kg PE-lined PP woven bags, palletised (40 bags per pallet) and stretch-wrapped; optional 1,000 kg FIBC for inland distribution hubs.
Each shipment includes mill certificate of analysis (COA), commercial invoice, packing list, bill of lading and certificate of origin. Phytosanitary certificate and fumigation record provided where destination agriculture authorities require them. Third-party inspection at loading (SGS, Bureau Veritas, Cotecna) can be arranged for LC-backed or first-time buyer contracts.
Application programmes
Stone fruit orchards apply 150–200 kg/ha in early spring before bud break, followed by 100–150 kg/ha post-harvest to replenish K reserves. Table grape vineyards split 200–250 kg/ha between pre-flowering and veraison stages. Blueberry and raspberry plantings use 100–150 kg/ha at dormancy break and a lighter 50–75 kg/ha dose after final pick. Strawberry tunnels receive 100–150 kg/ha before planting and 50–100 kg/ha after renovation to support runner development and fruit firmness.
FAQ — NPK 12-12-17
How does NPK 12-12-17 differ from 12-12-12?
Both grades carry equal N and P at 12%, but 12-12-17 adds five percentage points of K2O (17% vs 12%). Total nutrient content rises from 36% to 41%, better matching potassium removal in perennial fruit and berry crops without shifting to a high-K specialty formula.
Which crops respond best to the 17% K2O fraction?
Stone fruit, table grapes, blueberries and strawberries benefit most — potassium drives sugar accumulation, skin colour and post-harvest firmness. Equal N and P support canopy renewal and root reserves between harvest cycles.
Is granular 12-12-17 suitable for drip fertigation?
Standard 2–4 mm granules dissolve too slowly for direct injection. Apply as broadcast or band incorporation; for drip-irrigated orchards, pair with a water-soluble NPK of similar ratio during peak uptake windows.
