Webtude of the Redfield C:N:P ratio of 106:16:1 for either phytoplankton or the deep ocean has been elusive. It has long been recognized that conditions exist under which phytoplankton stoichiometry diverges from the canonical Redfield ratio. Furthermore, a number of processes drive oceanic nutrient inventories away from the Redfield ratio, WebDec 16, 2004 · Deviations from Redfield stoichiometry may be attributable to surface adsorption of phosphorus rather than to biological processes, and this scavenging could affect the interpretation of marine nutrient inventories and ecosystem models.
