Abstract
    Losses of soluble compounds of Spartina anglica leaves were measured in laboratory experiments and in the field. Leaves were incubated in the laboratory in tanks with normal sea water and with biologically inactivated sea water. In the active medium and in the field, a distinct diphasic decay was observed. During the first 13 to 17 days the losses of dry weight and total carbon amounted to approximately 20% of the original quantity. Nitrogen and phosphorus dropped to about 30% and 60% of the original values respectively, both in the active and the inactive laboratory series, in the first 13 days. The rapid loss has been ascribed to a leaching process. In the final stages of the experiment, the nitrogen and phosphorus compounds in both the active and field series stabilized or even increased.
