IRRIGATION WATER and FERTILIZER
Know What’s in Your Water Before It Reaches Your Crop
Water is one of the most important inputs in any growing system. But it can also be a hidden source of problems. Poor water quality can contribute to nutrient imbalances, pH drift, salt stress, and long-term damage to plants, soil, or irrigation equipment. At QAL, we provide precise water testing services to help you monitor quality, diagnose issues, and protect your crop investment.

Why Test Your Water?
Even water that looks clean can contain levels of salts, bicarbonates, or trace elements that interfere with plant health.
Regular water testing helps you:
- Understand baseline water chemistry
- Evaluate compatibility with fertilizers or additives
- Detect conditions that may affect pH control or nutrient uptake
- Prevent buildup of harmful ions or salinity in soils and media
- Meet requirements for regulatory or certification programs
For hydroponic or recirculated systems, where water is reused, testing becomes even more important as nutrient and salt concentrations can shift rapidly.
