Why Solvita®?
The Solvita® CO₂ Burst Test measures how active your soil biology really is—something traditional tests don’t show. When microbes are alive and thriving, they "breathe out" CO₂ as they digest organic matter. That respiration level tells us how well your soil can:
- Cycle nutrients naturally
- Convert organic matter into usable nitrogen
- Support root health and long-term productivity
If you’ve been adding compost, cover crops, or reducing tillage, Solvita® shows if your soil-building efforts are paying off.
Why Soil Respiration Matters
- Active microbial communities = better nutrient cycling
- Low respiration = poor biological function or compaction
- High respiration = healthy soil—or signs of recent disturbance
Understanding your soil’s biological pulse helps you reduce reliance on synthetic inputs, avoid over-fertilization, and make better soil health decisions.
