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?
Andrew Robertson
03:26:45
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.
