Analysis of plant and soil components of an alder ( Alnus rugosa [Du Roi] Spreng.) community that had invaded the bed of an abandoned mill pond showed an average annual N accretion of about 85 kg/ha. Most (93%) of the N in the ecosystem was found in the soil and there was a strong correlation between soil moisture content and N concentration. This may have resulted in part from more favorable conditions for nodule functioning. The amount of N in the alder stand during the growing season was about equal to that contained in freshly fallen litter. About three‐fourths of the N in alder plants was found in stems and twigs but highest concentrations of N were found in leaves and nodules.
