18-18-18 fertilizer is one of the three main types of fertilizers used by farmers. It gets its name because it contains 18% nitrogen, 18% phosphorous, and 18% potassium.

These three nutrients come together to help plants grow big and strong. But what is fertilizer good for? What’s it made of? And how do you know if your plants need it?

18-18-18 fertilizer is a blend of equal parts nitrogen, phosphorus and potassium

18-18-18 fertilizer is a blend of equal parts nitrogen, phosphorus and potassium. The letters N-P-K stand for the amount of each in the fertilizer.

In this case, 18 stands for nitrogen (N), 18 stands for phosphorus (P), and 18 stand for potassium (K). For example, seeing 8-8-8 or 20-20-20 means there is twice as much nitrogen as phosphorus or potassium.

The benefits of this type of fertilizer include:

• It’s easy to apply evenly because it comes in granular form that you can spread over your lawn or garden beds by hand or with a spreader.
• Because it contains all three essential nutrients in equal amounts, it will help your plants grow healthy foliage and strong roots while promoting strong flower growth when used correctly during the growing season.

These three essential nutrients are plants’ primary nutrients to be healthy and grow well

Plants need three things to grow: nitrogen, phosphorus and potassium. These are called the “primary nutrients”, and all other nutrients plants need are referred to as secondary or micronutrients.

These three primary nutrients are usually listed on a fertilizer bag in order of how much of each is present in that particular fertilizer product. For example, if you see something like “18-18-18 N-P-K”, your fertilizer has 18% nitrogen, 18% phosphorus and 18% potassium by weight (at least).

N-P-K ratio

The N-P-K ratio of 18-18-18 fertilizer tells you that to feed your plants one pound of nitrogen, you’ll also apply one pound of phosphate (phosphorus) and one pound of potash (potassium).

Nitrogen is necessary for photosynthesis, growth and development. Phosphorus helps seed germination and root growth. Potassium keeps the plant vigorous by aiding in cell division.

18-18-18 fertilizer will help your plants grow healthily

18-18-18 combines the three most essential nutrients for plant growth: nitrogen, phosphorus and potassium. It’s a good choice for almost any type of plant you’re growing in soil, although it may not be ideal for plants grown hydroponically or in coco coir.

For example, if your vegetable garden has been suffering from low yields lately, try giving it an application of 18-18-18 fertilizer once every two weeks.

Conclusion

18-18-18 fertilizer is an excellent choice for providing all these nutrients in one application. You can use this fertilizer on its own or as part of an integrated feeding program that includes other types of fertilizers and soil amendments.
