Roots and Nutrient

The growth of a plant is closely related to the available nutrients in the soil. The normal growth of a plant requires about 16 essential inorganic nutrients. Among these nutrients, only carbon, hydrogen and oxygen are taken from the air and water, the rests are absorbed as ions by the plant's roots.
