Nutrients plants need to grow.

Plants need multiple elemental nutrients to grow. Plants get these nutrients through the water absorbed by its roots.

The most essential nutrient elements are called macronutrients and they include nitrogen, phosphorus, potassium and magnesium.

These nutrients provide important functions (jobs) for the plant. The chart below names the nutrient and the important function of that nutrient for a plant.

Nutrient Function
Nitrogen (N) To form chlorophyll, compound needed for photosynthesis
To form amino acids, the building blocks of proteins
Phosphorus (P) To help the plant convert other nutrients into a usable form and help use and store energy for the plant
Potassium (K) To move water, nutrients and carbohydrates in the plant
Magnesium (Mg) To store chlorophyll for the plant
