Several studies have demonstrated the importance of nonorthophosphate compounds, including some of relatively high molecular weight, in phosphorus cycling in aquatic ecosystems. This paper reports results from a laboratory study indicating that some of the soluble phosphorus released by microbes associated with coarse and fine detritus in streams is of relatively high molecular weight (>5000 daltons) and that this phosphorus is subsequently utilized, but at rates considerably lower than for orthophosphate.
