Stability Metrics

These metrics describe how long biochar is likely to remain stable in soil and maintain its benefits over time.

Property	Why it plays a role
Fixed Carbon	Higher fixed carbon indicates greater stability and long-term carbon sequestration.
Lignin Content	Lignin increases resistance to decomposition.
H/C Ratio	Lower ratios mean higher aromaticity and greater stability.
O/C Ratio	Lower ratios indicate more stable and recalcitrant carbon.
Aromaticity	Higher aromatic content improves resistance to microbial breakdown.
Alkali Content	Influences interaction with soil minerals and nutrient retention.
Degradation Rate	Tells how fast biochar will break down in soil over time.
