Universol

Reliable water-soluble nutrition for everyday growing confidence.

Universol is designed with growers’ reality in mind

Universol is one of the most widely used water-soluble fertilizer ranges for ornamental pot plants and container nursery production. Developed by experts who understand the practical challenges growers face, Universol is designed to deliver consistent nutrition throughout the crop cycle, reliably and without complication.

By combining high solubility with balanced formulations, Universol supports stable plant growth across a wide range of cultivation situations.

Flexible solutions, without added complexity

Universol fertilizers can be used individually according to crop stage, or combined to fine-tune nutrition when needed. Certain formulations are suitable for A+B tank systems, while others can be used as a single tank solution, offering flexibility across different irrigation setups.

Despite this flexibility, the principle remains the same: Universol delivers stable nutrition that works across different systems, substrates and growing approaches, without requiring constant adjustment.

Universol products are known for their reliability, safety and consistent quality, offering dependable performance and a strong quality-to-price balance.

To assess irrigation water quality, the most commonly measured parameters are:

  • pH (acidity)

  • EC (electrical conductivity)

  • Water hardness (calcium, magnesium, bicarbonate)

In addition to these, other elements and factors may be considered depending on the specific growing conditions.
