How does a Compost Aerator Work?

It creates an aerobic atmosphere by adding vital oxygen and moisture to the mixture. The tip of the aerator will stab the compost heap to create large deep air pockets inside the compost. This pulling and pushing action will heat the pile for moisture, air, and proper decomposition. Some financiers may use a pitchfork or shovel to perform this process, but this only works if you have only one box / small pile.

Reasons behind using a Compost Aerator?

Always remember that regular airing of your fertilizer will bring oxygen to the pile regularly and thus speed up the process of getting fertilizer in 5-8 weeks instead of 4-8 months. If you do not use a fertilizer aerator, the pile will only collect the decaying bacteria. Therefore, without an adequate supply of oxygen, the decomposition process will slow down, and thus some problems such as strong odor (smells like ammonia), compost attracting unwanted critics (such as rats, insects, flies, rats) Cause Take a look at some of the reasons why you should use a fertilizer aerator.

  • Reheats the Pile:

Did you know that the center of a healthy compost heap should be at 120 degrees Fahrenheit? The circulation of fresh air and the intermittent flow of oxygen will cause the entire pile to slip to some extent, which is necessary for proper decomposition. Also, organic matter (produces nitrogen) in compost helps to generate heat and keep it in an aerobic state.

  • Creates Passageway for Moisture:

Whenever the material starts to decompose, the pile will start shrinking and shrinking in its size, as a result of which the remaining compost will cool down quickly without rotting. Therefore, to prevent this problem, you will need to use a compost aerator to expose more particles and decompose the process with proper diffusion of air, heat, and moisture (thereby reheating the pile itself). Allows the mixture to slip to accelerate.

  • Eliminate Odors:

If the pile of manure becomes stale, it should be left without air for a long time. The odor is an indication that there is too much moisture or nitrogen in the pile. Therefore, if you eat compost (repeated rotation of the mixture) it helps to reduce the odor.

How a compost aerator works best than other composting tools?

Most financiers wonder why they should buy a compost eater when they have tools like shovels, forks, or whips. Here are some reasons why Aerator works better than others.

  • They are specially designed to get into the bottom of the compost and turns the heap evenly in big, compacted piles or in a bin (somewhat difficult with a fork or spade) to ensure the air and moisture present for the decomposition process.
  • The usage of an aerator will make your work without getting messy, as it works without splashing the liquid compost or making the hands dirty.
  • The handles on the aerators will allow you to work without much strain on the back or shoulders unlike a trowel or hand forks do.
  • The aerators are easy to use, clean, and maintain and you can easily manage the compost without the accumulation of odors.

Frequently Asked Questions

1)How a compost aerator improve compost in the pile?

Using a compost aerator, it will take a few weeks (instead of months) for food or garden scrap to turn into soil, even the technique of distributing bacteria, moisture, and air. The ideal compost should also have layers of green waste and gray waste. So to achieve this a compost aerator will work well in balancing these wastes. To improve this process, regular inspection is required if the fertilizer is smelly and wet (or) adding some green material, such as adding brown material.

2) Why should I compost?

Fertilizer is an organic material that can be added to the soil to make it more fertile. The Environmental Protection Agency (EPA) says that about 30 to 30 percent of what we dispose of food scrap and yard waste will produce methane gas (which causes global warming). Therefore, composting is an effective way to minimize the amount of waste and also control the odor generated by garbage. Another important factor is that it acts as a rich organic fertilizer that you can use to grow healthy plants in your garden.

3) What should I need to set up a composting pile or bin?

First, you must choose at least 3 square feet of outdoor space and a bin for your compost. If you are worried about the shape or smell of compost piles by ordering out of the palace or shopping at your local gardening store, you can opt for a closed bin. The bun should be about 3 feet in diameter and not longer than your waist. Also, use a fence or chicken wire to protect the bun from animals.

4) What can I compost?

You can add almost any waste from your kitchen and garden. To keep your manure healthy, you need to keep the right balance between green waste (moist material like fruit and vegetable waste) and brown waste (dry matter such as dry leaves, wood scabs, or old newspapers). The supply of green matter is nitrogen, which helps build new soil cell structures, and the supply of gray matter feeds carbon-breaking organisms. Also, make sure the manure needs moisture (sprinkle the manure with water) and air. Avoid adding plant waste, milk, or animal products to your fertilizer as it will start to smell after a few days and start attracting pets.

5) How to and who can use this compost aerator?

Anyone who has made compost or compost should know that it is hard work and less baking work as it requires physical strength to complete the work. Older people, young children, and others who are out of condition should avoid using a compost aerator but can use a tumbling compost base. Converting compost into a bin properly is not an easy task but if done properly you can get the best results. Instead, use commercial scraps that contain small open matter so that you do not become a natural compost. Also, remember to use a compost aerator every few weeks to check the humidity level. Remove compost if the pile looks too dry for proper decomposition.


A compost aerator is an essential gardening tool that helps to spread the heat and moisture throughout the air by filling the compost with manure to increase the decomposition process and get natural fertilizer through it. Therefore, choose the best aerator that offers features such as comfortable grip handles, construction quality, height, ease of use, durability for long-term use.
