IN A NUTSHELL Given the incredible importance of fungi in our world, Dianne was curious if inoculants improved lettuce and onions yields, as these two species are known to grow in relationship with arbuscular mycorrhizal fungi (AMF).
- In 2019, she used AMF inoculants for the first time and observed particularly large, healthy lettuce and onions.
- In 2020, she set-up a randomized and replicated trial comparing two inoculants to uninoculated controls for Ariana, Cantarix, Nevada and Skyphos lettuce and Patterson onion. While they were also large and healthy, Dianne detected no effects of the inoculants yield.
- She wonders if the design of the trial was flawed because she unsuspectingly inoculated and/or resuscitated the mycorrhizal community of her whole garden in 2019.
