What Is 20-0-0 Fertilizer Used For?

The 20-0-0 fertilizer is a substance that provides plants with one or more of the essential nutritional elements for their normal vegetative development.

What is 20-0-0 fertilizer used for? The 20-0-0 fertilizer is responsible for delivering and returning to the earth the necessary nutrients for the proper growth of plants, trees, meadows, and shrubs. It is made with nitrogen and micronutrients to optimize plant health—ideal for golf course tees, fairways, sports field, and home lawns.

I always recommend using a fertilizer; this 20-0-0 is great if you have a big backyard. 

This fertilizer is great for: 

  • Killing major broadleaf weeds while feeding your lawn with 20 percent nitrogen formulation
  • Controls mallow, dandelion, knotweed, chickweed, plantain, clover, purslane, and many broadleaf weeds.

I recommend using Spectracide Weed & Feed 20-0-0.

You can also use the 20-0-0 granular fertilizer for your garden.

20-0-0 fertilizer meaning

If you’re a new gardener, you may have considered the numbers that come in the fertilizer bags, which is a common question to have. 

With so many number combinations, these compost/fertilizer bags can appear intimidating for beginners.

For example, you may see a combination of numbers like 10-10-10, 20-10-20, or actually almost any other combination. 

So what does all this mean?

These numbers are really called NPK values and speak to the estimation of the three macronutrients that plants use.

When you buy fertilizers, you can see three numbers on the box or bag. 

The first number refers to nitrogen; the second is phosphorus and the third potassium. 

The numbers reveal the percentage of nutrients a fertilizer bag has.

And it is calculated as follows.

If you have a bag of 5-10-5 fertilizer, and it weighs 10 pounds, it means that 5 percent or a half-pound is nitrogen. Now you can figure out the amount of phosphorus and potassium.

If the number on the bag is high, it means there is a greater amount of nutrients.

For instance, if you have a fertilizer 20-5-5 that means there is five times more nitrogen than there is phosphorus or potassium.

A 20-20-20 fertilizer has twice the concentration of nutrients as a 10-10-10 fertilizer.

These numbers are used to calculate the amount of fertilizer to apply to equal 1 pound of the nutrient you add to the soil. 

To give you another example, if you have a 10-10-10 fertilizer, divide 100/10; the result means you need 10 pounds of the fertilizer to add 1 pound of nutrients.

A fertilizer can also contain only 1 macronutrient, for example, 20-0-0, which means it only contains nitrogen.

What does npk mean?

Each macro-nutrient of the fertilizer is responsible for a specific job!

Nitrogen (N) is responsible for the growth of leaves on the plant.

Phosphorus (P) is responsible for the growth of the root, the flower, and the fruit’s development.

Potassium (K) helps the plant to function well in general.

Conclusion: What is 20-0-0 fertilizer used for?

It’s a great fertilizer perfect for growing grass and taking care of your lawn; it has a good amount of Nitrogen, which provides a fast and healthy development. 

Plus, it’s quite easy to use.
