Soil Carbon and Nitrogen Changes in Forests of Walker Branch Watershed, 1972 to 2004

Changes in soil C and N concentrations and contents in four samplings during a 32-yr period on Walker Branch watershed in Tennessee were determined and compared with previously measured C and N fluxes and with changes in ecosystem C and N pools during this period. Soils showed significant increases...
