Finding Your Next Compost Starter: A Buyer's Guide

A compost starter, also known as an “activator” or “accelerator,” is composed of bacteria and fungi targeted at starting the decomposition process. You will find a lot of biological activities occurring during the process of decomposition. It goes beyond just grass and leaves dying; it involves the bacteria working all day long to decompose the organic matter.

Things to Consider Before Buying a Compost Accelerator

If you are still reading this article, it means you are serious about getting better results from your composting. Here are a few tips you should consider if you want to buy a compost accelerator.

An abundance of active ingredients

One way to know if a compost activator will be good enough is by the volume of active ingredients. The correct volume of ingredients will help boost decomposition while also helping with cellular replication and decomposition.

Presence of organic formulas

The right organic accelerator ought to be composed of as many organic ingredients as one can imagine. Because most people who get into composting do so due to its environmentally friendly nature, the organic formula content is vital. Do not buy compost activators that are made up of too many synthetic ingredients and chemicals.

Nitrogen constituents

The very best accelerators are often made up of nitrogen-rich ingredients and extra elements such as calcium and magnesium. With these components, the bacteria component of your compost will grow faster, thus boosting the process of decomposition.

Brand reputation

One way to know if you are making the right choice is to check the brand’s background and its products. You can quickly ascertain this by checking online for reviews and customer feedback on the products. It is always safer to deal with a brand that offers good customer service and after-sales support.

Cost

The final thing to consider will be the cost of the accelerator. While compost accelerators aren’t exactly the most expensive things out there, the quality of the product most often depends on the cost. Therefore, be on the lookout for product quality before you consider the price.

How Compost Starters Work

Compost piles help you leverage the power of nature. The food materials and plant matter placed in the stack will break down naturally with time. The different stuff combined in the pile will become dark material that is exceptionally rich in nutrients. When they are placed in garden and landscape areas, the compost enriches the soil to give your plants better nutrients.

Compost accelerators help in speeding the decomposition process which happens in a pile. The major component of the booster includes microbes and minerals which help with decomposition.

Benefits of Compost Starters

Here are a few reasons why you should get yourself composter starters.

Helps speed up the composting process

The average compost heap takes a full year to produce compost. With the right accelerator, you can speed up the entire process by helping to naturally boost the compost heap to get quality compost within 21 days.

Helps in increasing compost quality

Compost accelerators help increase the compost heap’s temperature, which helps break down the compost into more minor constituents while keeping the much-needed nutrients.

They are natural

Most reputable compost accelerators are made using a hundred percent organic components. This will help you gain the needed level of reassurance for producing healthy and organic compost, which helps contribute to organic plant growth.

Helps in sterilizing compost from pathogens

The accelerator will help boost the compost temperature piles to temperatures above eighty degrees to make sure that any harmful diseases or pathogens are killed off while the compost gets sterilized.

Tips for Using a Compost Accelerator

  • Ensure you only add fresh materials such as garden weeds, lawn clippings, and raw kitchen vegetable peelings
  • Do not add cooked food to this accelerator as it will draw vermin. Cut or shred waste into smaller pieces where it is possible, especially with woody stems.
  • Ensure you cover the heap to retain the moisture content
  • Finally, regularly turn the heap to allow the air required for a quicker decomposition effect. When you are ready, make sure you spread the compost on your garden as a soil improver or mulch and keep all materials not composed at the bottom of the heap.
