What Is a Compost Accelerator?

Anything that speeds up the rate of composition is known as a compost accelerator. People add compost accelerators to their compost piles for it to work quickly. It has fungi and bacteria packages in a concentrated ratio. These fungi and bacteria start the decomposing process in the compost pile.

A compost accelerator makes the decomposing pile decompose quickly. Compost piles have bacteria inside them that are already decomposing the organic materials. Insects such as termites, worms, etc., perform this task at the macroscopic level.


Do You Need a Compost Accelerator?

Compost accelerators are great to accelerate decomposition, but do you need them?

One thing to keep in mind is that not all compost accelerators are made of environment-friendly materials. Some cheap compost accelerators can be dangerous for the environment in the long run. 

In addition to that, you can find compost accelerators that have inorganic packaging. When thrown in the compost pile, its packaging can reduce the compost’s quality.

What to do then? You can do proper research on compost accelerators before getting one. If the compost accelerators are of sustainable practices, compost accelerators worth the price.

You won’t need a compost accelerator, to begin with. That is because whatever compost pile you have will decompose on its own. However, compost accelerators are good supplementary products to spare some cash.


What Is a Good Compost Accelerator?

There are hundreds if not thousands of compost accelerators available in the market. How can you determine which one is good and which one is bad?

A good compost accelerator will have the correct volume of active ingredients to boost decomposition. As decomposition is an organic process, ensure that your compost accelerator is made of organic materials. 

Nitrogen helps in bacteria growth in the compost pile. So, look for accelerators that have nitrogen-rich materials. Calcium and magnesium help speed up the acceleration too.

A lot of brands make compost accelerators. To find the best one, look for brands with a good reputation. While you’re at it, check user reviews posted online. The last thing to consider is the cost. Although they aren’t as expensive, keep an eye on the quality of the product regardless of its price.

So, here’s what you got to do.

  • Make sure that the composter has the correct volume of active ingredients.
  • It is made of organic materials.
  • Ensure that it has nitrogen with elements such as calcium and magnesium.
  • The brand should have a good reputation.
  • Quality over price.


How Do You Make a Compost Accelerator?

Material List

If you can’t find a reliable compost accelerator, then you don’t have to worry. Because you can make your compost accelerator. For this, you’ll need the following materials.

  • 1 gallon of water
  • 5-gallon bucket
  • 1 can of warm beer
  • 1 can of cola
  • ½ cup of household ammonia.
  • 1 shovel
  • 2-3 shovels full of soil


Step by Step Guide

Once you’ve collected all the materials, it’s time to make a compost accelerator. Follow our step-by-step guide to make your very own compost accelerator.

Step 1:

Take the 5-gallon bucket, and pour 1 gallon of water into it. Water is necessary because decomposing bacteria and fungi require dark and moist conditions. The compost piles tend to get dry, which can affect decomposition speed.

Step 2:

Add a can of warm beer to the bucket. It can be a cheap beer, as long as it’s not light. Open the beer can and let it sit for 24 hours. This will remove all the fizz. Beers contain yeast that increases the growth rate of bacteria and fungi.

Step 3:

Add 1 can of cola to the bucket. Make sure that it’s not sugar-free. The sugar will provide the bacteria and fungi with a ready carbon source.

Step 4:

Add ½ cup of household ammonia. The nitrogen-rich ammonia will reduce acid’s percentage in the compost.

Step 5:

Stir the compost accelerator well until the ingredients blend. Pour it slowly over the compost pile. Add in 2 or 3 shovels of garden soil. Garden soil contains microbes that will accelerate decomposition.

Step 6:

Stir the compost lightly with the shovel to distribute the compost accelerator and soil in a pile. With this, your compost pile won’t have any hot spots.


How Long Does It Take for A Compost Accelerator to Work?

If you’re buying a compost accelerator, you won’t be satisfied with its quality unless you know its accuracy. Without a compost accelerator, your compost will take 3 months to 12 months to decompose.

Whereas adding in a compost accelerator will start the decomposition instantly. A good quality compost accelerator that naturally boosts its speed will make a huge difference. It will take the 1-year duration to 3 weeks or even less.


Is There a Way to Speed Up Composting?

To speed up the composition process, you can use the following tricks:

Size of Organic Materials

If you have chopped and shredded materials, they will decompose quickly. Compared to larger pieces of organic materials.

Type of Organic Materials

For fast decomposition, a correct ratio of carbon to nitrogen is required. Experts suggest that a 30:1 ratio is perfect for decomposition. For greens, you can use kitchen scraps that are rich in nitrogen. Whereas corn stalks etc., are rich in carbon.

How Often Do You Turn Your Pile

If you turn your pile more often, it will help bacteria because too much heat inactivates them. Turning your pile will significantly increase the decomposition speed. It will provide the pile with oxygen.

Moisture

Moisture plays an important role in decomposition. Too much moisture will end up replacing air in a pile. Whereas too little will slow or stop the decomposition. 40% to 60% moisture ensures efficient composition.


Conclusion

You won’t always need a compost accelerator. If your pile is there for months without any development, it is time to introduce the compost accelerator. 

Compost accelerators are beneficial if you need prepared compost. They will speed up the process so that it takes up to 3 weeks for prepared compost.

Remember that a compost accelerator alone can’t speed up the process. For this, you need to ensure that the materials inside are in the correct combination. And that they are chopped up to the correct size.
