Can too much potash burn plants?

Although extra potassium may not damage plants directly to begin with, it will eventually have serious indirect effects on overall plant nutrition. Excess potassium affects overall plant nutrition by preventing the plant from taking up other mineral nutrients, in particular magnesium, iron, zinc, and calcium.
