Spatial distribution of copper, organic matter and pH in agricultural soils affected by mining activities

The Aconcagua River Basin, located in north-central Chile, is an important agricultural region of the country. However, several copper mining industries are also located in this basin. A total of 103 topsoil samples were collected at varying distances from mining industries. There were no statistica...
