Lupine influence on soil C, N, and microbial activity was estimated by comparing root-zone soil (LR) to nonroot-zone soil (NR) collected at Mount St. Helens. Samples were collected from 5 sites forming a gradient of C and N levels as a reflection of different locations and varying volcanic disturban
