Where this formulation fits

Use Blue for balanced mid-season feeding for nursery, pot and bedding crops. 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.

Where hard or soft irrigation water presents particular challenges, compare the dedicated Universol Hard Water and Soft Water ranges before selecting a feed.

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.

ICL Universol Blue 25kg FAQs

What is the NPK analysis?

The declared NPK analysis is 18-11-18 (N–P₂O₅–K₂O), with 2.5% MgO and trace elements.

When is this formulation most useful?

It is designed for balanced mid-season feeding for nursery, pot and bedding crops. Select it in the context of your wider nutrition programme.

Can I use it through fertigation?

Universol is a water-soluble fertiliser range used in professional feeding programmes. Confirm your irrigation equipment, stock-tank dilution and water quality are suitable.

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?

Keep it sealed in a cool, dry place and prevent moisture entering the bag.

Does water quality affect product selection?

Yes. Irrigation-water hardness, bicarbonate content and existing nutrients can affect which Universol formulation is appropriate.
