NPK refers to the three essential macronutrients required by plants for healthy growth and development: nitrogen (N), phosphorus (P), and potassium (K). Each of these nutrients plays a critical role in various physiological processes within the plant, such as photosynthesis, root development, and fruit production. Nitrogen promotes leafy growth and overall vigor, phosphorus supports root and flower formation, and potassium contributes to disease resistance and fruit quality. Understanding and managing NPK levels in soil or fertilizers is essential for optimizing plant nutrition and maximizing crop yields.
