ICL Universol Hard Water 225 25kg is a professional water-soluble fertiliser for high-potassium feeding in hard irrigation water with elevated bicarbonates.
With a declared analysis of 11-10-28 + 2% MgO + trace elements, this formulation allows growers to select nutrition for a specific crop stage and irrigation-water profile.
ICL's Universol range uses its Bright Solution System and colour-coded formulations to help professional growers prepare consistent feeding programmes. Supplied in a 25kg bag.
Key benefits
- Declared NPK analysis: 11-10-28
- Includes 2% magnesium oxide and trace elements
- Water-soluble nutrition for professional horticultural feeding programmes
- Formulation selected for high-potassium feeding in hard irrigation water with elevated bicarbonates
- 25kg commercial bag
Where this formulation fits
Use Hard Water 225 for high-potassium feeding in hard irrigation water with elevated bicarbonates. Crop response depends on the species, growth stage, root-zone conditions and the balance of nutrients already supplied by the growing medium and irrigation water.
This Hard Water product is designed for water with elevated bicarbonate levels; it should not be treated as interchangeable with a soft-water formulation.
Preparing & applying the feed
Dissolve the fertiliser in water using the current ICL mixing and application guidance for the product and your crop. Check irrigation-water analysis, including alkalinity and EC, when setting a fertigation programme.
Monitor stock solution clarity, feed EC and pH, crop growth and drainage. Avoid assuming a single concentration is appropriate for all crops or irrigation systems. Check concentrated stock-tank compatibility before mixing with other fertilisers, especially calcium-containing products.
Managing a professional nutrition programme
Consider how this water-soluble feed complements any controlled-release fertiliser already present in the substrate. Review nutrition as crops establish, grow and finish, rather than relying on a fixed recipe for the entire production period.
Store sealed in a dry area, protect from moisture and follow the current product label and safety information when handling fertilisers.

How do I choose a feeding concentration?
Base the concentration on crop demand, water analysis, substrate EC and the current manufacturer recommendations; monitor the feed solution and crop response.
Can it be mixed with other fertilisers?
Do not assume all products are compatible in a concentrated stock tank. Follow the ICL product-specific mixing guidance and conduct a compatibility check before changing the programme.
How should I store an opened bag?
