- Despite the difference in disturbance that turning the cores could
have caused, the results suggest that mycorrhizal fungi and field
incubation of litter acted to additively increase the proportion of 13C left in cores.
- Synthesis. Apart from stimulating litter
decomposition as previously shown, mycorrhizas can also stabilize C
during litter decomposition and this effect is persistent through time.

Arbuscular mycorrhizal fungi enhance soil carbon sequestration in the coalfields, northwest China
A pulse-labeling experiment showed that in temperate prairie, about 4–6% photoassimilates were facilitated via AMF10. Simultaneously, AMF enhanced 16% soil CO2 efflux when Lolium pernne roots were colonized and 8% carbon supply was derived from AMF in a barley field13.
Consequently, AMF inoculation resulted in remarkable greater carbon sequestration.

Subsoil Arbuscular Mycorrhizal Fungi for Sustainability and Climate-Smart Agriculture: A Solution Right Under Our Feet?
Therefore, stabilization of soil aggregates by mycorrhizal hyphae in the
subsoil can contribute substantially to the protection and thus
sequestration of soil organic matter (SOC) (Figure 2A).
A better soil structure also improves soil pore connectivity, leading
to increased interactions between soil microbes, and, consequently,
likely increased competition for nutrients. If AM fungi could outcompete
decomposers for nutrients, they would be able to indirectly reduce
decomposition activity and thus potential loss of added or stabilized
carbon

About 107 g C m−2 was sequestered by AMF over a period of three years.
Our results suggest that AMF are more tolerant to increases in
temperature than other microbes or fine roots. The dramatic loss of soil
C and stable soil aggregates under warming found earlier at this site
were not attributed to a decrease in AMF biomass or CNew. Despite a low AMF standing biomass, its contribution to SOC may be substantial.
