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.

A method is presented that positions polar hydrogen atoms in protein structures by optimizing the total hydrogen bond energy. For this goal, an empirical hydrogen bond force field was derived from small molecule crystal structures. Bifurcated hydr...
