Soil Amendments, Physicochemical Properties, and Metal Accumulation in Soils and Vegetables of Volcanic and Non-Volcanic Regions in Ecuador

Heavy metal contamination in agricultural soils threatens food security and public health, especially in volcanic regions where ash alters soil properties. This study evaluates the effects of soil amendments on physicochemical properties, nutrient availability, and heavy metal accumulation in ash-af...
