Hydrogen (H), derived almost entirely from water, is one of the 17 essential nutrients necessary for plant growth. Hydrogen, along with carbon and oxygen, are the three primary elements plant use in the largest amounts, and they perform as the building blocks for plant growth.otassium (K) is one of the essential nutrients and is taken up in significant amounts by crops. Potassium is vital to photosynthesis, protein synthesis and many other functions in plants. Itâs classified as a macronutrient, as are nitrogen (N) and phosphorus (P). Plants take up K in its ionic form (K +).
1 Phosphorus is referred to as a primary nutrient because of the high frequency of soils that are deficient of this nutrient, rather than the amount of phosphorus that plants actually use for growth. 2  The remaining essential elements are the micronutrients and are required in very small quantities.
