摘要: Abstract Forest floor mineral soil mix (FMM) and peat (PMM) are common cover soils sources of organic matter for reclamation open-pit mining disturbed land in the Athabasca oil sands region. Coarse woody debris (CWD) can be an additional source provide nutrient habitat plant growth. However, effect CWD on nitrogen (N) cycling reclaimed has not been studied. A laboratory incubation experiment was conducted to assess chemical effects a extract gross net N transformation rates FMM PMM using 15 pool dilution method. The used simulate leachates (with rainwater as control) that produced field. simulated leachate studied 2 (FMM vs PMM) × 2 (CWD addition) factorial design. There no difference mineralization between PMM, although were greater than ( p 4 + immobilization PMM. Gross nitrification (N/IA) decreased by decreasing NH availability. Addition superior autotrophic due high C/N ratio extract. We conclude will have availability Leachates from would decrease increasing rates.
