The quantities of the nutrient elements N, P, K, Ca and Na in Pistia stratiotes L. and in water from the Volta lake were determined and compared. Nitrate-N content of lake water alone was found to be most consistently related with plant characteristics. The data were used to estimate the amounts of the elements bound in P. stratiotes biomass on the lake, and the importance of the nutrient composition of P. stratiotes for alternative approaches to control of the weed is indicated.
