- Intervention effect Cation leaching was accelerated in the pH 3.1 rain treatment in red spruce.
- Mechanism Cation leaching in red spruce is driven by atmospheric inputs of H+ and SO42−.
- Intervention effect Soil pH and exchangeable Ca2+ and Mg2+ pools decreased under the pH 3·1 rain treatment in red spruce.
- Intervention effect Exchangeable Al3+ increased in the organic horizon under the pH 3·1 rain treatment in red spruce.
- Intervention effect Calcium and Mg2+ fluxes in red spruce throughfall were enhanced at pH 3.1.
- Intervention effect Foliar Mg2+ concentrations in red spruce were reduced at pH 3.1.
- Intervention effect Ozone exposure had no effect on throughfall or soil solution ionic flux in red spruce.
- Intervention effect Ozone exposure had no effect on throughfall or soil solution ionic flux in loblolly pine.
- Mechanism Acidic deposition could impact high elevation red spruce forests via enhanced soil acidification that mobilizes Al3+.
- Association Acidic deposition could reduce availability of important base cations in high elevation red spruce forests.
- Association Acidic deposition could increase foliar leaching in high elevation red spruce forests.
