To answer this question, we added N, P, and N + P to a tidal freshwater marsh dominated by Zizaniopsis miliacea (Michx.) (giant cutgrass) in Georgia, USA, for &amp;#64257;ve years to determine their effects on aboveground and belowground biomass and nutrient (N, P) uptake. Nitrogen and P were applied twice per year at an annual rate of 50 g m&amp;#8722;2 year&amp;#8722;1 and 10 g m&amp;#8722;2 year&amp;#8722;1, respectively. Aboveground biomass and leaf C, N, and P were sampled in August of each year. Belowground biomass and C, N, and P content were measured in August of year &amp;#64257;ve. After two years, plots receiving N and N + P had signi&amp;#64257;cantly greater aboveground biomass than the control and P plots. This trend continued through the &amp;#64257;fth year of the study and resulted in two to three times more aboveground biomass at the end of the &amp;#64257;fth year in the N (1570 g m&amp;#8722;2) and N + P (1264 g m&amp;#8722;2) plots relative to P (710 g m&amp;#8722;2) and control (570 g m&amp;#8722;2) plots.
