Abstract

It is commonly believed that fine-textured soils developed on carbonate parent material are well buffered from possible acidification. There are no data, however, that document resistance of such soils to acidic deposition exposure on a timescale longer than 30-40 years. In this paper, we report on directly testing the long-term buffering capacity of nineteenth century forest soils developed on calcareous silt loam. In a chemical analysis comparing archived soils with modern soils collected from the same locations similar to 100 years later, we found varying degrees of forest-soil acidification in the taiga and forest steppe regions. Land-use history, increases in precipitation, and acidic deposition were contributing factors in acidification. The acidification of forest soil was documented through decreases in soil pH and changes in concentrations of exchangeable calcium and aluminum, which corresponded with changes in communities of soil microfauna. Although acidification was found at all three analyzed locations, the trends in soil chemistry were most pronounced where the highest loading of acidic deposition had taken place.

Three decades of observed soil acidification in the Calhoun Experimental Forest: Has acid rain made a difference?

Journal Article Markewitz, D; Richter, D; Allen, H; ... - Soil Science Society of America Journal

Three decades of repeated soil sampling from eight permanent plots at the Calhoun Experimental Forest in South Carolina allowed the authors to estimate the rate of soil acidification, the chemical changes in the soil exchange complex, and the natural and anthropogenic sources of acidity contribution to these processes. During the first 34 yr of loblolly pine (Pinus taeda L.) forest growth, soil pH, decreased by 1 unit in the upper 0- to 15-cm of soils and by 0.4 and 0.3 units in the 15- to 35- and 35- to 60-cm layers, respectively. Throughout the 0- to 60-cm horizon, base cationmore »« less

Acidification, buffering, and salt effects in the unsaturated zone of a sandy aquifer, Klosterhede, Denmark

Journal Article Hansen, B; Postma, D - Water Resources Research

Acidification of groundwater in a noncalcareous sandy aquifer at Klosterhede, Denmark, is the result of acid rain deposition. In the 4- to 5-m-thick unsaturated zone the pH ranges from 4.2 to 4.9 with Al concentrations of up to 0.8 mmol L{sup {minus}1}. The groundwater at the top of the saturated zone still has a pH below 5. Deposition of sea salt affects the solute profiles, and its importance varies both spatially from the forest margin to the inner part of the forest and temporally through seasonal variations in infiltration and dry deposition. As a result, pulses of high solute concentrationsmore »« less

Soil evaporation and organic matter turnover in the Sub-Taiga and Forest-Steppe of southwest Siberia

Journal Article Kayler, Zachary; Brédoire, Félix; McMillan, Helene; ... - Scientific Reports

Southwest Siberia encompasses the forest-steppe and sub-taiga climatic zones and has historically been utilized for agriculture. Coinciding with predicted changes in climate for the region is the pressure of agricultural development; however, a characterization of the soil water and carbon dynamics is lacking. We assessed current soil water properties and soil organic carbon turnover in forests and grasslands for two sites that span the forest steppe and sub-taiga bioclimatic zones. Soil evaporation was 0.62±0.17mm d-1 (mean±standard error) in grasslands and 0.45±0.08mm d-1 in the forests of the forest-steppe site. Evaporation at the sub-taiga site was 1.80±1.70mm d-1 in grasslands andmore »« less

An H{sup +} ion budget approach for evaluating three decades of forest soil acidification

Journal Article Markewitz, D; Richter, D; Allen, H - Bulletin of the Ecological Society of America

The acidity of a forest soil affects a wide range of ecological processes and is in turn affected by many of these processes. Hydrogen ion budgets may be used to integrate the array of processes that interact to produce and consume forest soil acidity. Three decades of forest soil observation, in the 0-60 cm layer, in a loblolly pine plantation, reports a mean annual acidification, in KCl-exchangeable acidity, of 1.33 kmolc/ha. During this period soil pH decreased by as much as one pH unit. Changes in soil base saturation, acid quantity and acid strength were all observed. H+ budget calculationsmore »« less
