Universol – Precision plant nutrition for nurseries and fertigation

Universol arose from the needs of professionals and nursery growers to provide their crops with a constant source of nutrients throughout all phases of their development.

The Universol by ICL range is one of the most commonly used solutions by nursery growers and ornamental producers who require high-performance water-soluble fertilizers for fertigation.

These are crystalline NPK fertilizers, completely water-soluble, designed to be applied using irrigation systems, injectors, or professional fertigation. Each Universol formula is identified by a specific color, allowing technicians to precisely adjust plant nutrition according to the crop phase.

Thanks to its Bright Solution technology, these fertilizers dissolve quickly and completely, preventing residue in irrigation tanks and ensuring homogeneous nutrient distribution.

This allows for:

• uniform plant growth
• better root development
• greater color intensity in leaves and flowers
• greater control of plant growth

For this reason, Universol has become a benchmark in precision plant nutrition for nurseries, ornamental production, and professional floriculture.
