Best Compost Aerator – Which Compost Turner?

Last Updated on June 19, 2021 by Grow with Bovees

Compost aerators, sometimes called compost turners are simple garden tools that help speed the decomposition of compost by mixing it.

Composting is a great way to recycle your yard waste and kitchen scraps, but it takes time.

If you turn the compost periodically, you’ll speed the decomposition process and get the finished compost sooner.

Aerating your compost offers myriad different benefits, most notably accelerating decomposition in your compost pile. Aerating aka turning your compost pile makes a world of a difference in making compost within 4 – 8 weeks rather than 6 – 8 months, and here’s why!

Every pile of compost needs a periodic influx of oxygen to activate the bacteria. If the bacteria feel sluggish due to a reduced oxygen supply, your compost heap may decompose slower, at lower temperatures, and possibly emit odor.

There are several ways to turn a compost pile including manual turning with a pitchfork or shovel, or easily with a compost tumbler, bin and a compost aerator.

When deciding between a compost tumbler or compost bin, bins have a larger capacity so you can turn more compost, whereas compost tumblers feature a smaller capacity, so you can’t spin larger loads.

Buying the best compost aerator however can be a bit overwhelming, given the many models available. But we’ve diligently researched this segment, and narrowed down on 5 best compost aerators that will help you turn your compost pile easily and efficiently.

Compost Aerators Buying Guide

When shopping for the best compost aerator, you’ve got several options to choose from, making it a bit challenging to get the right one for your needs. But here are a few things to consider ensuring you buy one that gets the job done right!

Types of Compost Aerator

There are several types of aerators available — corkscrew, plunger models and the crank compost aerator type.

If you’re mixing a small amount of compost, then you should be fine buying a corkscrew type aerator, whereas if you’re dealing with tough compost material, then a plunger-type aerator with spikes will help your composting process with relatively little effort.

Design and Size of Compost Aerators

Aerators can be ordered in a wide range of sizes, generally between 12-inches to 38-inches. If you don’t mind putting your back into the task, a smaller size aerator is best suited for you, but buy a taller model if you’re suffering from back issues or simply want to make the job as easy as possible.

Build Quality

Compost aerators can be made from either aluminum and stainless steel. While both materials are highly durable, you want to buy one that is rustproof or at the very least, treated to resist rust.

Comfort Padded Handles

Using a compost aerator, especially for long periods of time can take a toll on your hands. To prevent this strain, buy a compost aerator tool that’s fitted with padded grips on the handles.

Should You Aerate Your Compost Pile?

The big question when it comes to compost piles is to turn or not to turn? While cool piles of compost may not necessarily need turning, they could definitely benefit from periodical aeration to open some gaps in the oxygen-deprived spaces of the piles.

Hot piles of compost do need frequent aeration because their microorganisms suck up the oxygen in their open spaces fairly quickly. You should basically aerate any compost heap that has started producing ammonia or gone anaerobic.

Why Is Water Important for Compost Piles?

Water is an important nutrient in your composting process, as it helps keep the pile’s temperature regulated. Moisture levels need to be present in the right amounts because too much or too little water can actually hurt the pile, which in terms of numbers is 40 percent to 60 percent water.

Water is an essential nutrient for most if not all life including the microorganisms and insects that help decompose compost. If there’s too much water in your compost pile, these microorganisms won’t break down the compost as effectively.

Is There an Easier Way To Introduce Air Into Compost Besides Turning It?

There is no easy way per se of aerating compost, but you can run a perforated-pipe along the ground so that both ends stick out the outside of the pile. Then, run a second pipe vertically, and then build your compost pile around the vertical pipe, and over the bottom pipes. The goal of the pipes is to deliver air to the inner bulk of the pile.

How Often To Turn Compost

The guidelines to aerate a compost pile are pretty simple, where it is recommended that you turn small-batch piles of compost every few days for the first two weeks. You can tone the schedule down to once a week for the next four to eight weeks.

For add as you go piles, turn the pile every time new scraps are added. Take note that you should also check the moisture level of your compost pile periodically, and remoisten if necessary.

Where To Find the Best Finished Compost

The short answer is at the bottom of the bin, which the reason some compost bins have trap doors to easily remove the finished material, or else you can do it with a compost shovel. Pro tip: composted material is finished or ready for use when it’s dark, brown, and crumbly.

How To Use Compost Aerators

Before learning how to use a compost aerator, you should decide whether you’re going to turn the compost on its own or into two or three other bins, which takes a bit more effort.

But even though compost bins are used by millions of people, the downside to these bins is they’re taller, making it difficult for many to reach in and turn the material with a fork or shovel.

With an aerator, especially one that’s taller in height, you can easily turn the pile. To get started with a compost aerator, you first have to thrust it as deep as possible into the middle of the pile. Next, pull up the aerator while turning it to thoroughly mix the compost pile.

Final Thoughts on The Best Compost Aerator Tool

Aerating is probably one the best treatments you can give your compost piles, as it introduces oxygen, and helps it decompose quickly. There are several composting tools you can use to aerate your compost pile, like a compost turner, but an aerator works best, given the fact that you don’t really have to bend over into your compost bin to aerate.
