Is birch a suitable reference in estimating dinitrogen fixation in alders by isotope dilution?


, : Is birch a suitable reference in estimating dinitrogen fixation in alders by isotope dilution?. Plant and Soil 118(1-2): 43-50

Seedlings of Alnus incana (nodulated and non-nodulated) and Betula papyrifera were fertilized with varying amounts (0, 10, 25, 50, 100, 250 and 500 micro g N/g soil) of labelled ammonium-N or nitrate-N.
