Universidad Cato´lica de Chile, Av. Vicun˜a Mackenna 4860, Santiago, Chile(Received 30 January 2001; Accepted 12 April 2001)Abstract—A survey of copper levels in agricultural soils of central Chile revealed two soil clusters—one with a mean copper levelof 162 mg/kg and one with a mean copper level of 751 mg/kg of soil. Samples of soils from both soil clusters were characterizedon the basis of physicochemical characteristics, and copper extractability was compared by saturation and CaCl
