Inorganic nutrients are those that do not contain carbon in their structure. Water and minerals are the only two inorganic nutrients. Minerals such as calcium, iron, and potassium are essential for plant growth and development. They are necessary for bone health, the regulation of fluid balance, the transmission of nerve impulses, muscle contraction, and the transport of substances across the cell membrane.
Inorganic nutrients are absorbed by plants directly, without passing through the growing medium. This is similar to inserting an IV into plant veins. The nutrients are immediately available and can be absorbed by the plant regardless of whether it needs or wants them at the time. Organic nutrients, on the other hand, contain carbon in their structure.
Carbohydrates, lipids, proteins, and vitamins are all organic nutrients. They must pass through the growing medium before they can be absorbed by plants. Inorganic nutrients are essential for healthy plant growth and development. They provide essential minerals that plants need to survive and thrive.
However, it is important to use them responsibly to avoid over-fertilization and other problems.
