Indicative ranges in the species notes (nitrogen fixation, biomass, planting windows) come from European cover-crop agronomy literature and are not source-linked per row. The carbon gate still applies to any per-region coefficient that lands on this surface.

What's missing

These partner regions have not contributed a cover-crops source yet. A short note to the regional lead usually does it — they know which manual or trial dataset is the right one.
