In Summary

Soil OC is a significant source and sink of atmospheric CO2

Soil is a complex, biologically active medium

Soil OC is not one material

Changes in SOC can be measured directly or can be modelled

The C sink value of soils is limited BUT increasing and maintaining SOC has many benefits for improved productivity and soil resilience
