Water storage capacity of mosses

Md – dry weight of the whole sample [g];
Mdg – dry weight of the leafy twigs [g];
Mdp – dry weight of the rhizoids [g];
Mds – dry weight of the soil fraction associated with the rhizoids [g].
S0 – initial moisture content of the sample [g/g];
Mf – weight of the sample before the experiment – in fresh state [g];
Md – weight of the dried sample [g].
Smax – maximum water capacity – related to dry weight [g/g];
Mw – weight of the sample after sprinkling [g];
S – current water retention capacity [g/g]
S [%] – the amount of rainfall that was retained on the fresh moss-soil sample;
P – the dose of water used to simulate rainfall [g];
