Compound Fertilizer is the fertilizer which contains two or three nutrients of N, P, K. NPK fertilizers are three-component fertilizers providing nitrogen, phosphorus, and potassium. It is available in powder or granular form. Compound fertilizers show their nutrient content with three bold numbers on the package. Represented by three different major nutrient content: Nitrogen, Phosphorous, and Potash (Potassium), we can describe such content with the letters N-P-K. Nitrogen helps plant foliage to grow strong. Phosphorous helps root development and promote flowering. Potassium (Potash) is important for overall plant health and helps in fruiting. Imbalance fertilizers usage will affect growth and hence more susceptible to attacks by diseases and pests.
