Following the appointment of the new Cabinet, the Forest Sector now reports to the ministère des Ressources naturelles et des Forêts, while the Wildlife and Parks Sectors report to the ministère de l'Environnement, de la Lutte aux changements climatiques, de la Faune et des Parcs. Adjustments will be made to the website over time.

Mineral nutrition, dinitrogen fixation, and growth of Alnus crispa and Alnus glutinosa

Summary

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.
