These minerals elements are necessary for plant growth and development. These are also classified in macronutrient and micronutrients on the basis of amount required by plants.

In addition to the essential mineral elements are the beneficial elements, elements which promote plant growth in many plant species. These are Silicon, sodium, cobalt, and selenium.
