Published in Can. J. For. Res. 15 : 855-861
ln vitro cultures of Alnus crispa (Ait.) Pursh and Alnus glutinosa (L.) Gaertn. were used to estimate critical foliage levels of selected nutrients for optimal growth and dinitrogen (N2) fixation. For A. crispa to obtain 90% of maximum growth and N2 fixation, foliar levels of 0.12% P, 0.13% Mg, less than 0.31% K, and less than 0.04% Ca on a dry weight basis were needed. For A. glutinosa, the critical levels were 0.138% P, 0.10% Mg, 0.29% Ca, and ~ 0.20% K. From all the deficiencies observed, P had the more pronounced effects on N status of both species.
