Journal of Soil Science and Environmental Management

J. Soil Sci. Environ. Manage.

Copper is a micronutrient required for plant growth. However, it can have negative effect on plant growth if the concentration is too high. The aim of this study was to examine copper concentrations of leachate from soil columns treated with copper based fungicide. A 2 × 4 factorial arrangements consisting of two soil types (0 to 60 cm sample depth) and four rates of copper based fungicide concentrations (0, 1.88, 3.75 and 7.50 g/L ) was used... Read more
