Résumé
Six classes of forest floor material were distinguished on the basis of morphology and N mineralization characteristics. Fermentation layer materials, matted together with fungal hyphae, had a high content of total and potentially mineralizable N (N0) and mineralized the most N during incubation. Decayed wood had the lowest level of total N and N0 and mineralized the least N despite a high inherent mineralization rate (k). Humified materials occupied a midrange, with the exception of those from thin residual horizons, which had high N0 values and low k-values. The significant differences in N mineralization among organic materials that are morphologically or ecologically distinct in the field suggest that it may be possible to assess site N fertility using intensive forest floor and soil survey data and information on the N characteristics of dominant horizon types. -from Authors
