Abstract
A significant non-symbiotic N-fixation occurs in glucose-amended soil samples of the surface horizon (0-7 cm depth). Nitrogen fixation is higher under aerobic than under anaerobic conditions. The rate of N-fixing activity exhibits seasonal variations which depend on the availability of energy substrates and are closely related to seasonal variations of soil and plant metabolic activity. In the beech-fir stand, which shows higher rates of soil metabolism, N-fixing activity is larger than in the beech stand. -English summaryFile in questo prodotto:
