NPK ratios
NPK ratios represent the proportion of three key nutrients—Nitrogen (N), Phosphorus (P), and Potassium (K)—found in fertilizers. For example, a fertilizer labeled 10-20-10 contains 10% nitrogen, 20% phosphorus, and 10% potassium by weight. Nitrogen promotes leafy growth, phosphorus supports root development and flowering, and potassium enhances overall plant health and disease resistance. These ratios help gardeners choose the right fertilizer for their specific plant needs, ensuring balanced nutrition for optimal growth.
