A balanced blend of Nitrogen (N), Phosphorus (P), and Potassium (K) is crucial for plant growth.

Studies by the American Society for Horticultural Science (ASHS) show that sufficient 

Nitrogen (N)

• Promotes healthy leaf development.
• Important for plant growth (structure), plant food processing (metabolism), and chlorophyll formation.
• Without enough nitrogen in the plant, the plant cannot grow taller, or produce enough food (usually yellow).

Phosphorus (P)

• Supports strong root systems.
• Involved in energy transfer, photosynthesis, transformation of sugars and starches & nutrient movement.
• Transfer of genetic characteristics from one generation to the next.

Potassium (K)

• Regulates water balance, stress tolerance in plants, movement of nutrients in plant tissue
• Enzyme activation that controls protein, starch and adenosine triphosphate (ATP) production.
• Regulates the rate of photosynthesis.
