Nitrate and phosphate uptake in streams at Coweeta Hydrologic Laboratory

ients are generally responsible for limitin freshwater ecosystems. An exception shaded headwater streams where auto:tion may be light limited (e.g. HYNES r 1980, LOWE et al. 1986). However, in lutrients may be important in regulating processes (ELWOOD et al. 1981, AUMEN et out the effort and expense of long-term idies, short-term injections of nutrients > demonstrate relative rates of nutrient i Solute Workshop 1990). The objective as to use this methodology to: ptake of two commonly limiting nutrilate and nitrate; isonal changes in uptake of both nutri-
