Diminished Soil Quality in an Old-Growth, Mixed Mesophytic Forest Following Chronic Acid Deposition

  author={Jared L. DeForest and Brian C. Mccarthy},
Abstract Human activities have increased acid deposition throughout the Ohio River Valley due to the large number of coal-fired power-generating facilities. The long-term effects of chronic acid deposition can include a decrease in soil pH, loss of soil fertility, and a decrease in base saturation—all of which can reduce forest productivity. Dysart Woods, a remnant old-growth, mixed mesophytic forest in eastern Ohio, has experienced a decrease in soil pH from 5.0 in 1971 to 4.6 in 1997, which… 

Tree Response to Experimental Watershed Acidification

Forest ecosystems in the Eastern USA are threatened by acid deposition rates that have increased dramatically since industrialization. We utilized two watersheds at the Fernow Experimental Forest in

Mycorrhizal Response to Experimental pH and P Manipulation in Acidic Hardwood Forests

It is hypothesized that shifts in mycorrhizal colonization and community structure help temperate forest ecosystems overcome an underlying P limitation by accessing mineral and organic P sources that are otherwise unavailable for direct plant uptake.

The Effects of Soil Phosphorus on Acer rubrum Fecundity

These findings support the hypothesis that the effects acid rain has on soil is contributing to the increase in A. rubrum populations, and enhance each other’s effects on A.rubrum fecundity.

Temporal soil enzyme patterns provide new insights into the nutrient economy of acidic hardwood forests

Ecosystem nutrient economies are commonly studied from the perspective of primary productivity in relation to nutrient availability, but a plant-specific view limits our ability to predict

Tree growth response to shifting soil nutrient economy depends on mycorrhizal associations.

Results support the hypothesis that AM trees respond positively to an inorganic nutrient economy and raise pH in acidic soils can be detrimental to ECM tree growth, but the exact mechanism for this response is unclear.

Evidence for Topographic Control of Tree Spatial Patterning in an Old-growth, Mixed Mesophytic Forest in Southeastern Ohio, USA1

It is concluded that topography can greatly influence spatial patterning, and that this and other abiotic variables should be taken into consideration in future studies on community structure.

Multi-year soil microbial and extracellular phosphorus enzyme response to lime and phosphate addition in temperate hardwood forests

While reported short-term microbial responses to nutrient enrichment experiments are common, we provide results from a six-year data set in response to field manipulations of soil phosphorus (P)

Temporal change in the herbaceous understory community of an old-growth forest: from seasons to decades

The results suggest the importance of adequately and simultaneously documenting vegetation changes at short, intermediate, and long-term timescales—especially for understanding the dynamics of temperate deciduous forest herb communities.



Changes in soil chemistry accompanying acidification over more than 100 years under woodland and grass at Rothamsted Experimental Station, UK

We have examined the effect that acid deposition and other sources of acidity have had over the last 110–140 years on soil under woodland (Broadbalk and Geescroft Wildernesses) and grassland (Park


Loss of base cations from forest soils can be accelerated by acid rain, by forest regrowth following harvest removals, and by declining inputs of base cations from atmospheric deposition. Calcium

Changes in soil phosphorus fractions and ecosystem dynamics across a long chronosequence in Hawaii.

Overall, long-term soil development across the chronosequence largely coincides with the conceptual model of Walker and Syers (1976).

Thirty Years of Change in Forest Soils of the Allegheny Plateau, Pennsylvania

Numerous studies have investigated the potential depletion of available base cation pools from forest soils in regions impacted by acid deposition. However, these studies mostly used indirect

Long-Term Effects of Acid Rain: Response and Recovery of a Forest Ecosystem

Long-term data from the Hubbard Brook Experimental Forest, New Hampshire, suggest that although changes in stream pH have been relatively small, large quantities of calcium and magnesium have been

Nutrient limitation and soil development: Experimental test of a biogeochemical theory

Walker & Syers (1976) proposed a conceptual model that describesthe pattern and regulation of soil nutrient pools and availability during long-term soil and ecosystem development. Their model implies
