Resumen:
Red alder (Alnus rubra Bong.) has been proposed for use in crop rotation due its ability to symbiotically fix atmospheric nitrogen. The ability of this species for increasing nutrient status and ameliorating site deficiencies have been recognized, however whether this will have an effect on a subsequent crop or if it can be used in a crop rotation scheme remains unknown. A Douglas-fir red alder conversion study established in 1984 may shed light on some of these issues. Results 20 years after establishment showed that the previous presence of red alder resulted in an overall increased productivity of the site compared to the adjacent Douglas-fir site.
