NPK compound fertilizer is a multi-nutrient agricultural fertilizer combining Nitrogen (N), Phosphorus (P₂O₅), and Potassium (K₂O)—the three primary macronutrients essential for plant growth. Formulated to match crop and soil needs, it ensures balanced nutrient delivery, supporting vegetative growth, root development, flowering, fruiting, and overall stress resistance. Common grades include 15-15-15 (balanced), 20-20-20 (high concentration), and custom-blended versions for specific crops.
