Your Soil. Your Water. The Complete Picture.

Finally—A Soil Test That Reflects Real-World Conditions

Your irrigation water doesn’t just hydrate—it changes how nutrients move through the soil. The TrueProfile™ Soil Test goes beyond conventional analysis by running two extractions: one with lab-grade water, and one using your own irrigation water. The result? A side-by-side view of how your water source affects nutrient availability, salt interactions, and soil health— just like it does in your field.

This is the ultimate tool for growers, agronomists, and consultants who need more than a snapshot—they need the truth from the root zone.

What Makes TrueProfile™ Different?

Most labs only show what’s theoretically available. But when water with high bicarbonates, sodium, or pH enters the system, it can lock up nutrients or cause soil structure issues.

TrueProfile™ reveals:

• How your water shifts nutrient availability
• If your soil is at risk of salt stress or nutrient tie-up
• The difference between lab conditions and field reality
