Macro-Element Water-Soluble Fertilizer
Macro-element water-soluble fertilizer is a nitrogen-phosphorus-potassium compound with secondary and trace elements. It dissolves completely and is intended for drip irrigation, drenching and foliar application as a crop nutrition input.
Please note: Agricultural use only — do not ingest. Export inspection / quota status and destination fertilizer registration requirements are confirmed per product name before quoting.

FAQ
Questions importers ask about this product
- What packing options are available for Macro-Element Water-Soluble Fertilizer?
- 25 kg PP woven bag with PE inner liner; 50 kg PP woven bag with PE inner liner; 1000 kg jumbo bag (FIBC) with PE inner liner; Private label and buyer-specific shipping marks available. Private-label printing and buyer-specific shipping marks can be arranged.
- Can you supply Macro-Element Water-Soluble Fertilizer to a specific specification?
- Yes. Send the grade, purity and any impurity limits your process requires and we will confirm what we can supply. Indicative specifications for our standard grades are listed on this page; the controlling values are those in the technical data sheet (TDS) issued for your order.
- Which documents are provided with a Macro-Element Water-Soluble Fertilizer shipment?
- Commercial invoice, packing list, bill of lading, certificate of analysis for the batch, and the technical data sheet (TDS) and safety data sheet (SDS) for the product. Certificates for specific destinations can be arranged on request.
- What is the minimum order quantity?
- Our standard export minimum is one 20'GP container (approx. 25 MT). For a first order we can discuss a smaller trial quantity.
- Which NPK ratios can a water soluble fertilizer manufacturer supply?
- The standard grades are 19-19-19 + 2MgO + TE and 20-20-20 + 2MgO + TE, the second at total nutrients ≥60%. Other ratios are formulated to the buyer's specification, so if your market runs a different balance for a crop or a growth stage, that is a specification conversation rather than a catalogue choice.
- Is it suitable for drip fertigation and for foliar feeding?
- Both. It is built to dissolve completely for drip irrigation, drenching and foliar application. Before you commit a programme, ask for a jar test against the water you will actually use — hard water and high-bicarbonate sources behave differently from soft water, and a five-minute test at your end prevents blocked emitters later.
- Do you supply fulvic acid or amino acid formulations?
- Our standard water-soluble grades are macro-element NPK with magnesium and trace elements. Fulvic acid and amino acid inputs are separate raw materials, and blends containing them are made to the buyer's specification — tell us the target analysis and the application and we will confirm what can be built.
