NPK Fertilizer: What Is the Role of Nitrogen, Phosphorus, and Potassium in Plant Growth and Development?
NPK fertilizer helps plants grow by supplying the three primary macronutrients: nitrogen, phosphorus, and potassium. These essential nutrients support leaf and stem growth, root strength, flowering, fruit development, and overall plant health. When the npk ratio matches the crop and growth stage, plants develop better, use water and nutrients more efficiently, and produce stronger yields.
