What Is a Compost and How Does It Work

What Is a Compost?

A compost is a mixture of organic materials that decompose over time, resulting in nutrient-rich soil amendment.

It can be created through various methods such as closed compost bins, open compost bins, compost tumblers, or trench composting.

Closed compost bins retain heat and moisture, while open compost bins are better for composting yard waste.

Tumbler bins are sealed containers that can be rotated to aerate and mix the waste.

Composting can also be done through trenching, which involves burying organic waste directly in the soil.

Trench composting is odorless and invisible, making it an easier alternative to maintaining a compost pile.

It can be done any time of the year, and earthworms and other soil organisms assist in the decomposition process.

Trench composting can produce finished compost in about 12 months or sooner under ideal conditions.

Did You Know?

1. Composting was practiced as early as 4,000 years ago in ancient Mesopotamia, where farmers used it to improve soil fertility and crop yields.

2. Composting can reduce methane emissions from landfills, as organic waste that is not composted produces methane gas when it decomposes anaerobically.

3. Did you know that worm composting, also known as vermicomposting, is a method of composting using red worms or earthworms? These tiny creatures help break down organic matter faster by speeding up the decomposition process.

4. Some notable figures were avid composters, such as Leonardo da Vinci, who believed composting to be essential for sustainable agriculture. He once said, “We know more about the movement of celestial bodies than about the soil underfoot.”

5. Compost can act as a natural pesticide. When used as a top dressing or mulch in the garden, it can deter pests and suppress weed growth due to its acidic nature and ability to create a physical barrier.

Types Of Compost Bins

Composting is a natural process that involves the decomposition of organic waste into rich, nutrient-filled soil called compost.

There are several types of compost bins that can be used for small-scale, at-home composting:

  • Closed compost bins: These bins are usually enclosed structures that retain heat and moisture, creating an optimal environment for the decomposition process. The open bottom of closed compost bins allows nutrients to travel into the soil beneath, benefiting nearby plants and promoting healthy root systems.

  • Open compost bins: These bins are better suited for composting yard waste. They can be as simple as a loop of chicken wire or a pile of materials on the ground. Open compost bins allow for easy access and aeration of the compost pile, facilitating the decomposition process.

  • Tumbler bins: These bins are sealed containers that can be rotated with a handle. The rotation aerates and mixes the waste inside, speeding up the decomposition process. Compost tumblers are particularly useful for those who want faster results and have limited space.

Composting is a valuable practice that helps in waste reduction and creates nutrient-rich soil for plants. Understanding the different types of compost bins available allows individuals to choose the most suitable option for their needs.

Benefits And Uses Of Compost Tumblers

Compost tumblers provide several advantages and benefits for composting. One of the main advantages is their ability to quickly convert waste to finished compost in a short amount of time. Some compost tumblers can produce this finished compost in as little as three weeks, making them a convenient option for those seeking fast results.

Another advantage of compost tumblers is their sealed container design, which reduces the likelihood of attracting pests and rodents compared to other composting methods. The sealed design also helps to contain any odors that might arise during the decomposition process, making compost tumblers suitable for urban and suburban areas where odor control may be a concern.

Moreover, compost tumblers are easy to maintain and convenient to use. The rotating mechanism allows for simple aeration and mixing of the compost, ensuring even decomposition of the waste. This eliminates the need for manual turning of the compost pile, making compost tumblers a time-saving option, particularly for busy individuals.

The Process And Advantages Of Trench Composting

Trench composting is an alternative method of composting that involves burying organic waste directly in the soil. This process takes advantage of the natural decomposition abilities of earthworms and other organisms in the soil.

One of the advantages of trench composting is its ability to help nearby plants develop water-conserving root systems. By burying organic waste in trenches, the roots of nearby plants are encouraged to grow deeper in search of the decomposing waste, resulting in stronger and more drought-resistant plants.

Trench composting is also an odorless and invisible method of composting. Since all the waste is buried underground, there are no unpleasant smells or unsightly compost piles to worry about. This makes trench composting particularly suitable for those who want to compost without drawing attention or causing any inconvenience to others.

Another advantage of trench composting is its ease of use. Compared to maintaining a compost pile, trench composting requires less maintenance and monitoring. Once the waste is buried, the earthworms and other organisms in the soil do the rest of the work, breaking down the organic matter and turning it into nutrient-rich compost.

Trench Composting Vs. Compost Piles: Which Is Easier?

When it comes to ease of use, trench composting has some advantages over traditional compost piles. Trench composting requires less physical effort since the waste is simply buried in the soil instead of being regularly turned and maintained in a pile.

In terms of odors and visibility, trench composting also has the upper hand. The waste being buried underground means there are no unpleasant smells or visible piles of compost to deal with. This makes trench composting a more discreet and convenient option, especially for those living in urban or suburban areas.

However, traditional compost piles have their own advantages. Compost piles offer more flexibility in terms of the amount and types of organic waste that can be composted. They are also more suitable for larger amounts of waste or for those who prefer to actively manage their compost pile by turning it regularly for optimal decomposition.

Ultimately, the choice between trench composting and compost piles depends on personal preference, available space, and the specific needs of the individual. Both methods have their own benefits and can contribute to the production of nutrient-rich compost for gardening and landscaping purposes.

Tips And Tricks For Efficient “Dig And Drop” Trench Composting

The “dig and drop” method of trench composting is an ideal choice for those with limited organic waste or space. This method involves burying the waste in small holes in the ground, providing a convenient way to compost in small quantities.

To ensure effective trench composting, it is recommended to cover animal products such as meat, grains, and dairy with 12 to 18 inches of soil. This helps to prevent pests and rodents from being attracted to the composting area and ensures proper decomposition of these materials.

Using markers can be a helpful strategy when practicing “dig and drop” trench composting. By marking the spots where waste has been buried, it is easier to avoid digging in the same spot twice. This prevents the disturbance of decomposing organic matter and ensures that the composting process remains efficient and undisturbed.

Trench composting can be done throughout the year, as long as the soil remains pliable and manageable. However, it is important to note that the process may take longer during colder months when microbial activity and decomposition rates are slower. Patience and regular monitoring of the composting area are key to successful trench composting.

Trench composting offers advantages such as:

  • Water-conserving root systems
  • Odorless and discreet composting process

The choice between trench composting and compost piles depends on personal preference and available resources. Taking into account tips and tricks for efficient “dig and drop” trench composting can help ensure successful composting and the production of nutrient-rich soil for gardening purposes.
