I think it would be more properly stated that plants use potassium,
nitrogen and phosphorous as essential elements just as animals do.
Potassium is required for proper ionic gradients across cell membranes,
nitrogen is necessary for amino acid and protein synthesis, etc.
Vitamins usually help important cellular chemical reactions occur and
elements are not considered to be vitamins.
