- Sponsor Seminars
These are scheduled events to help delegates test out the tools and platform we will be using for the Q&A and other events at the conference.
Our workshop program provides training and teaching in topics across geochemistry and related fields. We are currently liaising with the workshop organisers to ascertain if any workshops can become virtual. Any updates will be added to this page.

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!
