Fine root carbon content per fine root dry mass

Formal name:  fine root carbon content per fine root dry mass
Local identifier:  TOP548
Synonym Term:  fine root C content per dry mass
Related Term:  fine root C content
Related Term:  fine root C concentration
Definition:  The ratio of the quantity (SEP:quantity) of carbon (CHEBI:carbon atom) in the fine root (McCormack:fine root) to the corresponding fine root mass (PATO:mass) assessed after drying
Formal Unit:  mass unit / mass unit or amount unit / mass unit

Comment:  The quantity of carbon 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. We suggest to specify fine roots by branching order instead of diameter (< 2 mm).
