Dry mass

Definition

noun

(1) A reliable measure of the biomass (as opposed to fresh mass).

(2) The dry matter of a sample or of an object when completely dried (lacks or excluding water).


Supplement

Dry mass is a more reliable measure of mass than fresh mass because the former excludes the fluctuating water concentrations in the biological material measured which is present in the latter.


Compare: fresh mass
