Changes in nutrient availability and forest floor characteristics in relation to stand age and forest composition in the southern part of the boreal forest of northwestern Quebec
Changes in forest floor properties and nutrient availability along a boreal post-fire sere succession covering a time span of 231 years were assessed using soil analysis and exchange resins. A decline in pH (from 5.5 to 3.65), effective cation exchange capacity (CEC) (from 72.5 to 39.6 cmol(+)kg−1),...

Contrary to what has been reported so far for boreal forests, NO3 and NH4 concentrations did not decrease in the course of succession. Ammonium concentrations remained constant while those of NO3 reached their highest values at age 27, decreased abruptly between ages 27 and 47, and started to increase in older stands.
