  1. Physical, chemical and mineralogical properties of mine spoil derived from the Wise Formation, Buchanan County, Virginia

    … retard growth of non-tolerant plant species. Exchangeable bases are overestimated, but the salts are a nutrient source. K is low, but adsorption isotherms indicate that, unlike the naturally occurring soils of the locality, there is no serious problem of K-fixation in the spoils. NaHCO₃ gives …

  2. Taxonomy, genesis, and parent material distribution of high- elevation forest soils in the southern Appalachians

    … forests is underscored by high levels of exchangeable bases in surface horizons relative to lower in the profile. This suggests that disturbances to the forest floor resulting from fire, overgrazing, logging, or erosion could have a major impact on ecosystem resilience during stress.

  3. The geochemistry of fossil termite nests in Calitzdorp, Western Cape, South Africa

    … relative to the host soils. The enrichment of exchangeable bases derived from organic matter, including termite frass, and upward groundwater movement frequently leads to post-construction carbonate precipitation within termitaria. Fossil termitaria near Calitzdorp, Western Cape, South Africa, …
