Inorganic plant nutrients are obtained directly or indirectly from the soil (where they grow) and atmosphere. As the sources of these inorganic requirements are minerals, the elements are known as mineral nutrients and the nutrition is called mineral nutrition.

In the formation of carbohydrates, fats, and proteins, carbon, hydrogen, and oxygen play an important role. In addition to these three elements, plants need a variety of elements for their survival. The source of these elements is primarily the inorganic form of ions present in the soil.
