WebJan 22, 2024 · and then calculate that 38 is the N/P ratio. But this number is misleading, it has nothing to do with the Redfield ratio. To sort it out, I suggest using a generally accepted, easy way to convert the NO3/PO4 ratio into the N/P Redfield ratio: N/P Redfield = 1.53*NO3/PO4 Now coming back to the discussed question posed by Tales: WebOct 28, 2010 · The Redfield ratio, describing average composition of phytoplankton biomass (Redfield 1934, 1958), is the most broadly applied stoichiometric reference for nutrient limitation of planktonic production.This indicator is recurrently applied from global-scale oceanic biogeochemistry to management-oriented load-response models, and to algal …

WebMay 1, 1987 · The biogeochemical cycling of oxygen, phosphorus and carbon in the Baltic Sea is investigated using a natural coordinate conservation method. The mean Redfield ratio of oxygen consumption to phosphate production due to organic decomposition is found to be 159 ± 6 in the Baltic proper deep water.
