Go Beyond the Basics — Discover the Biological Life of Your Soil

Healthy soil isn’t just about nutrients and pH—it’s a living ecosystem. The Soil Health Test with Solvita® gives you a full-spectrum view of your soil’s physical, chemical, and biological health.

This test includes everything from nutrient levels and organic matter to the Solvita® CO₂ Burst Test, which reveals the biological activity driving nutrient cycling and root health. Whether you're managing a high-value crop, rebuilding poor soils, or improving sustainability, this test gives you the clarity to make better decisions.

Why Solvita® Matters

The Solvita® test is a rapid soil respiration method that estimates microbial activity by measuring CO₂ release from the soil. This matters because:

• Active soils = efficient nutrient cycling
• Microbial respiration indicates biological fertility, not just chemical
• Helps assess whether your soil amendments are building life—or just feeding plants short-term

By integrating Solvita® into your soil test, you can:

• Monitor your soil’s biological recovery over time
• Make better decisions about compost, cover crops, and microbial inoculants
• Predict how efficiently your soil can deliver nutrients to plants
