The productivity of natural stands of cattails (Typha latifolia) has been correlated with the amounts of nutrients in the soil and water. The direct effects of varying levels of nitrogen (N), phosphorus (P), and potassium (K) on productivity were examined in our study by growing cattails in Hoagland's nutrient solution. Concentrations of 1/4, 1/16, and 1/64 the amount of N present in complete Hoagland's solution (0.01 M) resulted in 63%, 48%, and 26% of the dry weight of plants grown in complete solution. Rhizomes used to start plants contained considerable amounts of P and K since growth in solutions with no P or no K resulted in dry weights up to 37% of that of plants grown in complete solution. Nutrient availability also affected plant morphology. Reduced N increased root growth up to 75% greater than that of plants grown in complete solution. 3 figures, 1 table.
