Silicon.<\/p>\n<p>Nitrogen, phosphorus, and potassium are the three main macronutrients that plants need to grow. Silicon is a micronutrient that is not as essential for plant growth, but it can still be beneficial in some cases.<\/p>\n<p>Nitrogen is essential for the production of proteins and nucleic acids. Phosphorus is essential for the production of ATP, which is the energy currency of the cell. Potassium is essential for the regulation of water balance and the opening and closing of stomata.<\/p>\n<p>Silicon is a structural component of cell walls and can also help to protect plants from pests and diseases. However, it is not as essential for plant growth as nitrogen, phosphorus, and potassium.<\/p>\n<p>In commercial fertilizers, nitrogen, phosphorus, and potassium are typically the three main ingredients.
