The numbers you see on packaging are the NPK ratios, which stands for nitrogen (N), phosphorus (P), and potassium (K). The higher the number, the more concentrated that specific nutrient is in the fertilizer. For example, a fertilizer labeled as 20-10-10 contains 20% nitrogen, 10% phosphorus, and 10% potassium.
Nitrogen (N): This nutrient is essential for leafy green growth. It promotes the development of lush foliage, stems, and leaves. Fertilizers with higher nitrogen content are beneficial for vegetative growth.
Phosphorus (P): Phosphorus is crucial for root development, flowering, and fruit production. It supports strong root systems and encourages the formation of buds and blooms.
Potassium (K): Potassium contributes to overall plant health and resilience. It helps regulate water uptake, enhances disease resistance, and improves tolerance to environmental stressors.
