Water-soluble fertilizers and special grade fertilizers
Fully soluble NPK special grades for drip and foliar feeding, and special fortified grades that combine nutrients with humic, seaweed or amino acids, made to order.
What we make to order
- Fully water-soluble NPK special grades to your specification
- Special grades fortified with humic acid, seaweed extract or amino acids
- Stage-specific grades: starter, vegetative, flowering and fruit development
- Packs for retail (1 kg) through bulk (25 kg bags and jumbo bags)
How special grades are chosen
Each water-soluble grade is named by its N:P:K ratio, and each ratio suits a different crop stage. Growers commonly use balanced grades such as 19:19:19 in vegetative growth, phosphorus-rich grades such as 12:61:0 at establishment, and potash-rich grades such as 13:0:45 or 0:0:50 at fruit development. Calcium and magnesium grades and micronutrient-fortified grades complete the range.
Special grades become more useful when they carry a biostimulant. Humic acid and seaweed extract are commonly combined with soluble NPK so one application feeds the crop and supports root activity or stress tolerance.
Common grades by crop stage
| Crop stage | Commonly used grade type | Typical purpose |
|---|---|---|
| Establishment and rooting | Phosphorus-rich grades (for example 12:61:0) | Root development |
| Vegetative growth | Balanced grades (for example 19:19:19) | Canopy and growth |
| Flowering | Phosphorus and potash grades with boron | Flowering and set |
| Fruit development and quality | Potash-rich grades (for example 13:0:45, 0:0:50) | Size, colour and quality |
Results vary with crop, soil, weather and practice. Follow the label, run a small trial first and scale what works on your farm. Nothing on this page is a guarantee of yield.

Questions buyers ask
What is water-soluble fertilizer?
A fertilizer that dissolves completely in water, so it can be applied through drip irrigation or as a foliar spray and is taken up quickly.
What are the common water-soluble fertilizer grades?
Common grades include 19:19:19, 20:20:20, 12:61:0, 13:40:13, 13:0:45, 0:52:34, 0:0:50, calcium nitrate and magnesium sulphate. Each suits a different crop stage.
What is 19:19:19 fertilizer used for?
It is a balanced NPK grade used mainly in vegetative growth through drip or foliar spray.
When should 13:0:45 and 0:52:34 be used?
Potash-rich 13:0:45 is commonly used at fruit development; 0:52:34 supplies phosphorus and potash, commonly at flowering. Follow a crop-wise schedule.
What are special grade fertilizers?
Grades formulated for a particular crop, stage or need, often fortified with micronutrients or biostimulants such as humic acid, seaweed or amino acids.
What is the price of water-soluble fertilizer (25 kg)?
Price depends on the grade and concentration, the form (liquid, powder or granule), the pack size, the order quantity and, for export, the Incoterm and destination port. We do not publish a price list because bulk, private-label and retail packs are priced differently. Send the grade, quantity and destination and we reply with a quote, usually within one working day.
Can you make a water-soluble grade under my brand?
Yes. We make special grades to your specification and pack under your private label.
