Summary

The effects of ammonium or nitrate-nitrogen on biological nitrogen fixation by an algal crust are compared. Nitrate-nitrogen up to 3.0 μmoles N g−1 sand/algal crust at 60% water holding capacity did not affect fixation, whereas an ammonium-nitrogen concentration of 0.2 μmoles N g−1 crust markedly depressed fixation. Consequences of these differential effects are considered.
