Plant nitrogen content per plant dry mass

Formal name:  whole plant nitrogen content per plant dry mass
Local identifier:  TOP520
Synonym Term:  whole plant N content per dry mass
Related Term:  whole plant N content
Related Term:  whole plant N concentration
Definition:  The ratio of the quantity (SEP:quantity) of nitrogen (CHEBI:nitrogen atom) in the whole plant (PO:whole plant) to the corresponding whole plant (PO:whole plant) mass (PATO:mass) assessed after drying
Formal Unit:  mass unit / mass unit or amount unit / mass unit

Comment:  The quantity of nitrogen 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.
