Symptoms
| |
Broadleaved trees: damage resembling those by drought stress – necroses on the leaf-border, rolling up of the leaf-border, red discoloration, premature leaf shedding; conifers: needles yellow or red, premature needle drop; direct effects (spraying) can also lead to burning damage on the needle surface. Since the salts commonly diffuse rather slowly into the soil, damage can appear years after the last immission.
