Abstract

The net productivity and nutrient storage of potassium (K), nitrogen (N), and phosphorus (P) by water hyacinth (Eichhornia crassipes [Mart.] Solms) were evaluated at several K concentrations in the culture medium (between 2 and 52 mg K liter^-1) using 1000-liter outdoor tanks for a period of about 4 months. Maximum plant biomass (3·1 kg (dw) m^-2) was reached at culture medium K concentrations of 12-52 mg K liter^-1. Potassium storage in water hyacinth tissue steadily increased at K supplies of up to 52 mg K liter^-1 with a maximum tissue K content of 72 mg K g^-1. Maximum N and P storage in the plant biomass was reached at K concentrations of 12 and 22 mg K liter^-1, respectively; further increases in K concentration did not increase either N or P storage.
