Ammonium chloride was injected into enclosures pushed into the sediment ... Ammonium kinetic uptake was then followed for two yours. Grey-sand bottom displayed the highest affinity was the same order of magnitude. Macrophytes, and microphytes (when macrophytes are absent), account for the bulk of ammonium bottom uptake. As a result, grey-sand bottoms with their dense macrophyte cover represent a sink for water column nitrogen and play a key role in nutrient cycling of the lagoon.
