The coppice dune and associated barren playa soils of Paradise Valley, Nevada contain large amounts of soluble salts, exchangeable sodium, and boron. The concentrations of salts and sodium are variable. Sodium and Cl appear to be the principal soluble ions. The pH at the surface is high (usually 9+). Exchangeable sodium percentage is high at the surface (30% +) and decreases with depth. Boron, while highly variable, is high enough at several locations to limit the growth of even tolerant species. Silica in the saturated extracts increases as the soil pH increases. Because of the salts, high pH, exchangeable sodium, and toxic concentrations of boron, even partial reclamation of these soils would prove difficult without an adequate supply of water, large amounts of amendments, and considerable expense.
