NPK 20-20-8
NPK is the abbreviation for the three main nutrients in fertilizers:
- N = Nitrogen: Promotes leaf and shoot growth.
- P = Phosphorus: Supports root formation, flowering and fruit set.
- K = Potassium: Strengthens plants, regulates water balance and increases resistance.
The numbers after NPK (e.g. 6-4-8) indicate the percentage of the respective nutrients in the fertilizer.
NPK = main nutrient ratio of a fertilizer .
