Water soluble NPK

Fully soluble NPK formulations across the full ratio range, built for fertigation and foliar feeding, with EDTA chelated trace elements in every grade.

About this group

Water soluble NPK is the backbone of any fertigation program: clean, concentrated nutrition that goes straight into the line and is taken up fast.

Every grade dissolves completely in water, including cold and hard water, and leaves no residue in the tank or the drippers. That makes the range suitable across different water qualities and pH conditions, in both soil-based and soilless growing.

The library spans the full ratio map, from balanced grades for general feeding to nitrogen, phosphorus and potassium led ratios for each crop stage, plus grades enriched with calcium, magnesium and sulphur. Trace elements are supplied in EDTA chelated form so they stay available to the crop across a wide pH range.

Each grade is offered in two tiers: an economic line for everyday programs, and a premium line built on potassium nitrate and low chloride raw materials for high value crops.
