Leaf iron content per leaf area

Formal name:  leaf iron content per leaf area
Local identifier:  TOP475
Synonym Term:  leaf Fe content per area
Related Term:  leaf Fe concentration
Related Term:  leaf Fe content
Definition:  The ratio of the quantity (SEP:quantity) of iron (CHEBI:iron atom) in the leaf (PO:leaf) or component thereof, i.e. leaf lamina or leaflet (PO:leaf lamina, PO:leaflet) per respective area (TOP:leaf area, TOP:leaf lamina area, TOP:leaflet area)
Formal Unit:  mass unit / area unit or amount unit / area unit

Comment:  The quantity of iron can be expressed either as a mass (with mass unit, e.g. gram) or as an amount (with amount unit, e.g. mol). The term concentration is polysemic and we suggest to not use it in this context.
