NPK is an abbreviation for Nitrogen (N), Phosphorus (P), and Potassium (K). These elements together provide nutrition for the soil.

Nitrogen: What is the function of Nitrogen (N)?

Nitrogen (N) promotes plant growth and also ensures that the leaf remains beautifully green. If there is too little nitrogen, the leaf will turn yellow and the plant will not grow well. With too much nitrogen, the plant will have larger leaves, but these will be very limp and watery. The plants will also be susceptible to fungi and diseases.

Phosphate: What is the function of Phosphorus (P)?

Phosphorus (P) is very important for the respiration and energy supply of the plant. It promotes root development, flowering, seed formation, and ripening of the plant. If there is too little phosphorus, there will be poor development of lateral roots and the leaf may take on an unusual color. With too much phosphorus, it can cause a shortage of zinc and iron.

Potash: What is the function of Potassium (K)?

Potassium (K) is needed for the transport of water and carbohydrates. Potassium also promotes plant firmness, improves root and fruit formation, and reduces sensitivity to drought and frost. With too little potassium, the leaves will wither, and there will be fewer large flowers and flowers of poor quality. If there is too much potassium, the plants will contain more water.
