- •
Coupled addition of Cu and Zn results in lower soil adsorption, especially for Zn.
- •
The free ionic species Zn2+accounted for more than 70% in soil solution.
- •
Cu in soil solution was mainly bound to organic matter (>50%).
- •
Excess of Cu and Zn damages photosynthetic apparatus and the plant enzymatic activity.
