Seems unable to unmute - I can’t unmute her either
Hi, Michelle - it seems like you may have an issue unmuting yourself. Are you on the most recent update of Zoom? Thanks!
ha ha ah ha@ David
please put questions in Q&A. thx

This is steve pacala. Can you let me turn on my video?
Hi, Steve. Once the countdown is finished we can swap screens :)
Question on human action and grassland fires in Africa, which produces about 1 GtC/yr, although net emissions is low.
Question — What are the implications of no-till or conservation tillage on other inputs — for example, herbicides and pesticides. If these tillage practices increase application rates — are these increased risks significant?
Sally, just a quick answer - in the case of reduced/no-till change the impacts vary greatly depending on why they tilled in the first place. Sometimes they till to control weeds, or to prep the soil for planting, or mix organic matter, or reduce compaction. In different soils and systems the risk from other management changes are very variable. Too hard to generalize really but certainly should be considered on a site-specific basis
Sally, in addition to Andrew's answer, the integrated solutions at a farm level that Francesca mentioned can also help mitigate risks of increased application rates in no-till or conservation tillage lands. Cover crops can in some cases be used to control weeds or reduce compaction in combination with no-till or conservation tillage.
I have to go — thank you all. Wonderful talks. See you tomorrow.
