The Presence of High Concentrations of Salts in the Soil

The presence of high concentrations of salts in the soil poses a problem for plants because:

A) if excluded by the root, they can make it harder for the root to extract water from the soil.
B) if the salts are not filtered from the transpiration stream, they can damage the plant.
C) salts can form insoluble compounds with organic forms of nitrogen that are then unavailable to the plant.
D) if taken up by the shoot, salts make the plant more palatable to large herbivores.
