Where this formulation fits

Use Hard Water 211 for nitrogen-led growth 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.
