In other words, how do plants eat? In order to live, plants need these 16 essential elements, called macronutrients and micronutrients. Macro Nutrients (primary nutes) • carbon (C) • hydrogen (H) • oxygen (O2) • nitrogen (N) • phosphorus (P) • potassium (K) • calcium (Ca) • magnesium (Mg) • sulfur (S) Micro Nutrients (Secondary nutes) • Boron (B) • Chlorine (Cl) • copper (Cu) • iron (Fe) • Manganese (Mn) • Zinc (Zn) • Molybdenum (Mo) Macronutrients and micronutrients Most of the plant is formed from Hydrogen, Carbon and Oxygen (~95% of the dry mass). Carbon comes from carbon dioxide (CO2) in the air. Hydrogen and Oxygen come from water. Note that this Oxygen must be available ‘mixed in the water’, as Dissolved Oxygen. The remaining macronutrients, Nitrogen, Phosphorus, Potassium, Calcium, Magnesium and Sulfur must b
