ABSTRACT:
We examined the effects of species, initial substrate quality, and site differences on woody root decomposition and its nitrogen dynamics in Sitka spruce (Picea sitchensis), Douglas-fir (Pseudotsuga menziesii), and ponderosa pine (Pinus ponderosa) dominated forests in Oregon, U.S.A. using a time series approach. Roots of fourteen species and five size classes were placed in the field to incubate and then collected at pre-planned intervals to determine mass loss and nitrogen content.
