Table 3 Flocculent and soil standardized major axis regression results for flow way 1 (FW 1) and FW 3 within Stormwater Treatment Area-2 for inflow, mid, outflow, and entire FW (ALL) regions. Stoichiometric comparisons include total carbon to total phosphorus (TC:TP), total carbon to total nitrogen (TC:TN), and total nitrogen to total phosphorus (TN:TP)

From: Evaluation of nutrient stoichiometric relationships among ecosystem compartments of a subtropical treatment wetland. Do we have “Redfield wetlands”?
