Abstract
Barium and manganese concentrations in radial growth increments of hea rtwood from Juniperus virginiana L. are used to examine changes in soi l reaction and sulfur deposition. Barium and Mn trends from trees grow ing on 2 sites with acid, low-Ca soils, signaled sulfur-induced change s in soil acidity after 1870, while Ba and Mn trends before 1870 did n ot. Factors controlling Ba availability are hypothesized to have chang ed from soil acidity before 1870 to precipitation of BaSO4 by increase d soil sulfate after 1870.
