Why do I not see any carbon sequestration for grassland?

Grassland is a great storage of soil organic carbon globally and thus CO2. However, new sequestration of grasslands is quite uncertain and is assumed to not capture any additional carbon. This complies with IPCC guidelines, where only grassland that was established over the last 20 years shows an increase in soil organic carbon. After that, it is assumed that a new equilibrium has been reached in the soil and the increase in soil has carbon has come to a stop.
