What is Water and Nutrient Solutions?

Water and Nutrient Solutions is a full-service portfolio for analysing irrigation water and nutrient solutions. The analyses identify salts, nutrients, harmful substances and microbiological risks, helping you maintain optimal growing conditions and safeguard crop quality.

Eurofins Agro tests all relevant water sources in greenhouse horticulture, including tank water, tap water, osmosis water, nutrient solution and drain water.

Why water quality matters

Good and sufficient water is a basic requirement for growing. Sodium and chlorine must remain low, and the EC must stay within crop-specific thresholds.
In recirculating systems, harmful substances may accumulate, drippers may become blocked, and pathogens such as bacteria, fungi and viruses may circulate through the system.

Water quality directly influences:
• Nutrient uptake
• Plant health
• Yield and produce quality
• System hygiene and recirculation safety

Biological water analyses

Biological analyses detect microorganisms that influence plant health, system hygiene or recirculated water safety.

Available biological tests include:

• DNA Multiscan
• Plant Doctor
• Human pathogens
• Soil Life Monitor
• Microbiome Profiling

These analyses help monitor system sanitation, track pathogens and support preventive crop health strategies.

When to use Water and Nutrient Solutions

Water and nutrient analyses are suitable for:

• Setting fertilisation strategies
• Monitoring nutrient solution composition
• Keeping recirculation systems clean and safe
• Early detection of harmful substances or pathogens
• Supporting certification and water quality standards
• Troubleshooting crop issues caused by water quality

Chemical water analyses

Chemical analyses give insight into the salts, nutrients and elements that determine fertilisation strategy and irrigation quality. Eurofins Agro offers tests for tank water, osmosis water, tap water, nutrient solutions and drain water. These analyses determine key parameters such as pH, EC, major ions and trace elements.
