Webamine the role of these cryptogamic crusts in the supply of fixed nitrogen and the constraints to that fixation. Nitrogen fixation rates (as measured by acetylene reduction) were highest in sites with a well-developed cryptogamic crust, lowest in sites with only bare mineral soil, and intermediate in sites with a partially developed crust. WebSUMMARY N and P, especially when added together, significantly enhanced CO2 assimilation rate in four moss species from a range of habitats on sub-Antarctic Marion Island. NO3− always caused a greater increase in assimilation rate than did NH4+, but this might have been due to Cl− added with the NH4+. Possibly for the same reason, K+ …
