NPK Fertilizer is one of the several nutrients that are needed by plants for their development and optimum growth. Plants won't generally grow to their full potential without these nutrients and plants will be more susceptible to disease and perform below their expected yield.

NPK simply mean Nitrogen (N), Phosphorus (P), and Potassium (K) also known as NKP fertilizer.

There are so many NPK fertilizer composition and combinations, e.g., NPK 10-10-10, NPK 20-20-20, NPK 10-8-10 and others.

People usually ask;

NPK fertilizer, what is it, and how does it work?
What does the NPK fertilizer ratio mean?
When to use NPK?
What's NPK fertilizer benefits?

The numbers on the fertilizer represent the value these nutrients contained in a certain quantity (e.g., a tin, a bag). The figures indicate the concentration of the nutrients in the fertilizer. Take, for instance, numbers on NPK fertilizer 20-10-10 have two times more nitrogen in it than phosphorus and potassium. A 20-20-20 fertilizer has an equal concentration of NPK.

These nutrients are quickly removed in the soil as a result of continuous farming and other environmental factors. In the tropics, soils are usually lacking with these three nutrients. Action must be taken to put back nutrients into the ground to create a quality environment for the healthy growth of plants.

Let's quickly look at the roles of these three nutrients in the life of plants
