- •
Increases in soil C stocks in Southern Africa with CA were lower than anticipated.
- •
Low C input, as a results of limited biomass production, limited soil C increase.
- •
In most study sites C concentrations was below critical levels after 2–7 years.
- •
Carbon sequestration should therefore not be oversold in CA promotion.
