Operationally Extractable Copper and Early-Stage Phytotoxicity in Vineyard Soils: Implications for Cu Risk Assessment and Soil Management
Long-term use of Cu-based fungicides in humid vineyards promotes Cu accumulation in topsoils, but plant risk depends on soil properties and on the Cu pools that are operationally extractable rather than on total Cu alone. In this study, soils were collected from vine rows and inter-row areas in 58 vineyards in Galici...
