@calestous @GroIntel this graph needs to be adjusted to (or at least compared with) total ag acreage for meaningful conclusions.
@GenomeEditor @calestous @GroIntel the number I'd like to see is food gross kcal/kg N
@jkellyca @calestous @GroIntel that's ideal but likely difficult to get data for rural parts of Asia/Africa. Inputs/area is easier to meas.
@GenomeEditor @calestous @GroIntel also interested to know if measure is only Haber N? Or are manures & composts included?
@jkellyca @calestous @GroIntel oh wow, that's a really good point. I'm sure it's almost entirely Haber. Locally sourced is too hard to track
