What is NPK?
NPK are the chemical symbols for Nitrogen (N), Phosphorus (P) & Potassium (K). These three elements are found in almost every type of soil sold are the amounts are normally listed on the bag or bottle under the NPK designation. For example, if a bag of soil is 15-18-20, it is referring to the ratio of NPK. The same is true on a bottle of fertilizer. The ratio of NPK will normally be listed somewhere on the label.
Nitrogen (N) : Nitrogen helps in making proteins that are used for foliage growth. Excessive Nitrogen will cause fast growth but poor flowering, . A Nitrogen deficiency causes stunted growth.
Phosphorus (P) : Phosphorus is key to strong root growth, flower development and larger seeds. An excess of Phosphorus causes poor growth and bleached or yellow leaves. A phosphorus deficiency causes leaves to die.
Potassium (K) : Potassium is important for overall plant health and development of flowers. Excess Potassium can cause (N) and (P) uptake to be blocked which would then lead to (N) & (P) deficiencies and issues. Potassium deficiencies lead to disease and overall poor plant health.
There are other nutrients and compounds that a plant needs, but they are often required in tiny amounts. Calcium, Magnesium, & Iron are needed by plants, but in minuscule amounts compared to NPK.
