Effects of CO(2) and Nitrogen Fertilization on Soils Planted with Ponderosa Pine

摘要

The effects of elevated CO(sub 2) (ambient, 525, and 700 (micro)l l(sup -1))and N fertilization (0, 10, and 20 g N m ^{yr) on soil pCO(sub 2), CO(sub 2) efflux, soil solution chemistry, and soil C and nutrients in an open-top chamber study with Pinus ponderosa are described.}
