Hi Emma, Great talk! Very cool to see the field experiments worked even better than the lab trials! How did the planted tub go? Did the plants survive, and did their root growth help or hinder aggregation? Cheers, Jess

Thanks Jess! We have some nice evidence of Fe-mineralisation around roots in all the containers, that I didn't show here. And field evidence also suggests that plants are important in Fe cycling that stabilises canga naturally. But in this experiment it was hard to discriminate the effect of the canga-plant-treatment compared to the unseeded treatments, because seed from the surrounding area blew in and germinated in all IBCs over the 10 months.. I think plant establishment will be critical in canga re-cementation in the real world though!
