Abstract

|
|
| Arbuscular mycorrhizal fungi have significantly contributed to weathering of the earth's surface since their evolutionary origin 400–500 million years ago. They have been a key player in the global carbon cycle over geological timescales. In order to reach the global warming targets as agreed at the Paris summit in 2015, implementation of negative emission technologies is necessary. Among the options, one of the simplest is "enhanced weathering", where silicate rock is ground into small particles to enhance weathering rate. Here we synthesize the ways by which mycorrhizal fungi interact with these particles when applied to agricultural fields, and suggest they may stimulate weathering by various direct and indirect mechanisms. We conclude that because the intensity with which mycorrhiza interact with soil is tightly related to plant provisioning of photosynthates in exchange for soil‐derived nutrients, weathering rates and hence carbon sequestration are likely to increase with agricultural activities that stimulate plant reliance on and investment in arbuscular mycorrhizal fungi. |
