Product overview — Water-Soluble NPK
Greenhouse and orchard buyers request water-soluble NPK bulk price from a supplier offering multiple fertigation grades — balanced 20-20-20 for vegetative growth, phosphorus-heavy blends at flowering, and potassium-forward ratios for fruit sizing. Unlike granular compound NPK, these soluble grades dissolve fully at field concentrations, protecting drip emitters and pivot nozzles from sediment buildup. Moisture stays below 0.5% and water solubility reaches 99% minimum, meeting the quality thresholds demanded by greenhouse A/B systems and open-field micro-sprinkler programmes.
Available ratios span the standard fertigation portfolio — balanced 20-20-20 and 19-19-19 for vegetative growth, phosphorus-heavy 10-30-20 for flowering transition, and potassium-forward 15-5-30 or 13-0-46 for fruit sizing and sugar accumulation. Buyers include protected-culture operators in Spain, Morocco and the Gulf, export berry and vegetable growers in Chile and Peru, and liquid-fertilizer blenders formulating ready-to-use concentrates for distributor networks across South Asia and East Africa.

Loading ports & logistics — Water-Soluble NPK
Multi-ratio water-soluble NPK portfolio ships in grade-labelled 25 kg PE-lined bags, palletised for dry container stuffing from 300 MT per ratio. Each N-P-K formula is bagged separately to prevent cross-contamination — specify required ratios (20-20-20, 10-30-20, 15-5-30, etc.) at enquiry so the correct grade is allocated from mill inventory. Dry 40 ft containers only; no bulk granular NPK logistics apply to soluble grades.
FOB from Black Sea and MENA soluble-NPK mills. CFR/CIF to fertigation distributors in Spain, Morocco, the Gulf and South Asia. Container programmes above 1,000 MT total can combine multiple ratios in separate holds or sequential container lots. Moisture protection: heat-sealed bags, desiccant sachets and covered warehouse transfer at discharge. Lead time 10–20 days after contract confirmation.
Packaging & documentation — Water-Soluble NPK
Standard export pack: 25 kg PE-lined PP woven bags, palletized and stretch-wrapped for container loading. One-tonne FIBC big bags available for inland distribution hubs and large greenhouse complexes. Each lot ships with mill certificate of analysis (N, P2O5, K2O, moisture, water solubility), commercial invoice, packing list and full bill of lading set. SGS or equivalent pre-shipment inspection on request. HS classification 3105.20 — mineral or chemical fertilizers containing nitrogen, phosphorus and potassium.
FAQ — Water-Soluble NPK
Which water-soluble NPK ratio suits each crop growth stage?
Use balanced grades such as 20-20-20 or 19-19-19 during vegetative establishment and transplant recovery. Shift to higher-phosphorus blends like 10-30-20 at flowering initiation, then potassium-forward ratios such as 15-5-30 or 13-0-46 during fruit sizing and ripening. Match the ratio to phenology rather than applying one formula all season.
How does water-soluble NPK differ from granular NPK of the same analysis?
Water-soluble grades are micronized and formulated for complete dissolution at fertigation concentrations, leaving no sediment in stock tanks or drip lines. Granular NPK of the same N-P-K label dissolves slowly and is intended for soil broadcast or bed incorporation. The soluble route carries a higher grade premium but is mandatory where nutrients enter through emitters.
Can chelated micronutrients be mixed with water-soluble NPK in one tank?
Yes, when micronutrients are in EDTA, DTPA or EDDHA chelated forms compatible with the irrigation water pH. Avoid combining concentrated calcium nitrate with phosphate-containing NPK in the same stock solution — calcium phosphate precipitation will foul filters. Use A/B tank systems or sequential injection when both calcium and phosphate are required in the same programme.
