How Can We Make Compost: The Ultimate Guide
How Can We Make Compost?
To make compost, you need a mixture of materials with a carbon to nitrogen (C:N) ratio of 30:1.
The composting process involves microbes and other organisms feeding on organic matter to break it down.
Various organisms like earthworms, slugs, snails, and insects assist in the breakdown of organic materials.
The ideal temperature for these microbes is 130º–140º F, which is achieved through their activity.
It is recommended to turn the compost pile once or twice a year to speed up the process.
The pile should not be built over 5 feet high to prevent compaction and allow air movement.
The compost should be harvested at the bottom of the pile annually.
Constantly adding fresh materials ensures a continuous decomposition process.
Another method is hot composting, which involves filling a bin with all ingredients at once.
This method generates significant heat and can produce compost in six to eight weeks.
Continually check the temperature, turn the materials, and add moisture until the volume reaches about 50% of the original.

Did You Know?
1. Certain species of worms, called “composting worms,” have a unique ability to eat and decompose organic waste material at a rapid rate, making them excellent for adding to compost bins.
2. Adding coffee grounds to your compost can help to speed up the decomposition process and also serves as a natural fertilizer due to its high nitrogen content.
3. Banana peels are not only compostable, but they also contain high amounts of potassium, which is a beneficial nutrient for plants and flowers.
4. Did you know that shredded cardboard and paper can be used as “brown” material in composting, providing a source of carbon to balance the nitrogen-rich “green” materials?
5. Composting can help reduce methane emissions, a potent greenhouse gas, as the organic waste that would otherwise end up in a landfill decomposes anaerobically and releases methane, while composting promotes aerobic decomposition.
The Ideal Carbon To Nitrogen Ratio For Composting
Composting is an effective and eco-friendly way to recycle organic waste and turn it into nutrient-rich soil. One key factor in successful composting is achieving the right balance between carbon (browns) and nitrogen (greens) materials. The ideal carbon to nitrogen (C:N) ratio for composting is 30:1. This ratio ensures proper decomposition and prevents the compost from becoming too high in nitrogen, which can lead to a smelly, slimy pile.
Carbon-rich materials include dried leaves, straw, wood chips, and shredded paper. These materials provide the energy source for the microbes involved in the composting process. Nitrogen-rich materials, on the other hand, include grass clippings, vegetable scraps, coffee grounds, and manure. These materials provide the necessary nutrients for the microbes to break down the organic matter.
To achieve the ideal C:N ratio of 30:1, it is important to have a good mix of both carbon and nitrogen materials in your compost pile. Adding too much carbon can slow down the composting process, while adding too much nitrogen can result in a smelly, anaerobic pile. By carefully balancing these materials, you can create a healthy and productive compost pile.
- Use carbon-rich materials such as dried leaves, straw, wood chips, and shredded paper.
- Include nitrogen-rich materials like grass clippings, vegetable scraps, coffee grounds, and manure.
- Aim for the ideal C:N ratio of 30:1 to ensure proper decomposition.
- Avoid an imbalance in carbon or nitrogen to prevent issues such as slow decomposition or a smelly pile.
The Role Of Microbes In The Composting Process
Microbes and other organisms play a crucial role in the composting process. These tiny organisms, including bacteria, fungi, and other microorganisms, feed on the organic matter in the compost pile and break it down into simpler components. This decomposition process releases nutrients and creates a rich, dark soil-like substance called humus.
Bacteria, in particular, are the primary decomposers in the compost pile. They consume the carbon and nitrogen materials and produce heat as a byproduct of their metabolic activity. The heat generated in the compost pile is a result of this microbial activity, and the ideal temperature for these microbes is around 130º-140º F.
Other organisms, such as earthworms, slugs, snails, millipedes, sow bugs, ants, and insect larvae, also assist in the breakdown of organic materials in the compost pile. These creatures help to shred and mix the materials, increase oxygen flow, and enhance the overall decomposition process.
By providing the right conditions, such as a balanced C:N ratio, moisture, and aeration, you can create an ideal environment for these beneficial microbes. Their activity is essential in transforming your kitchen and garden waste into nutrient-rich compost.
Maintaining The Ideal Temperature In The Compost Pile
Temperature is a critical factor in composting as it directly impacts the rate of decomposition and the overall success of the process. The heat generated in the compost pile is a result of microbial activity, specifically the metabolic activity of bacteria and other microorganisms. The ideal temperature range for these microbes is between 130º-140º F.
To maintain the ideal temperature in the compost pile, it is essential to turn the pile once or twice a year. Turning the compost helps to mix the materials and provides oxygen to the microbes, promoting aerobic decomposition. It also helps to distribute heat evenly and ensures that all parts of the pile are exposed to the microbial activity.
Additionally, it is important to regularly monitor the temperature of the compost pile. A compost thermometer can be used to determine the internal temperature. If the temperature drops below 100º F, it may indicate a lack of fresh materials, air, or water in the pile. In such cases, adding more materials and turning the pile can help to maintain the ideal temperature and ensure proper composting.
- Maintain the ideal temperature range of 130º-140º F
- Turn the compost pile once or twice a year to mix materials and provide oxygen
- Regularly monitor the temperature using a compost thermometer
- If the temperature drops below 100º F, add more materials and turn the pile
Best Practices For Building And Harvesting A Compost Pile
Building and harvesting a compost pile requires some considerations to ensure optimal results. When constructing the compost pile, it is important to follow certain guidelines. The size of the pile should be 3’x3’x3′ to allow for efficient decomposition and ensure proper airflow within the pile. Building the pile higher than 5 feet can lead to compaction and limit air movement, resulting in a slower decomposition process and unpleasant odors.
When adding materials to the compost pile, it is recommended to add fresh materials regularly. This practice ensures that the materials on top are in the early stages of decomposition, while the bottom of the pile is ready to use. By constantly adding fresh materials, you create a continuous cycle of decomposition, resulting in more uniform and consistent compost.
Harvesting the compost is another important step in the process. The compost should be harvested from the bottom of the pile annually, allowing enough time for the materials to fully decompose. This allows you to obtain mature and nutrient-rich compost for use in your garden or pots.
Tip: Keep in mind that composting can take several months to a year depending on the materials and environmental conditions. Patience is key!
By following these best practices, you can create a well-structured compost pile that efficiently breaks down organic materials and produces high-quality compost for your gardening needs.
- Ensure the compost pile size is 3’x3’x3′
- Avoid building the pile higher than 5 feet to prevent compaction and slow decomposition
- Add fresh materials regularly for a continuous cycle of decomposition
- Harvest the compost annually from the bottom of the pile for mature and nutrient-rich compost
The Process And Timeline Of Hot Composting
Hot composting is a method that allows for quicker compost production, usually in six to eight weeks. This process involves creating a compost pile with all the necessary ingredients at once and providing the optimal conditions for microbial activity and heat generation.
To begin hot composting, it is important to gather a variety of carbon and nitrogen-rich materials. These can include kitchen scraps, yard waste, grass clippings, shredded paper, and dried leaves. The pile should be built in layers, starting with a layer of carbon-rich materials and then alternating with nitrogen-rich materials.
Once the pile is built, it is essential to monitor the temperature. Within 24 hours after the bin or pile is filled, the temperature should start to rise as the thermophiles (heat-loving bacteria) consume nutrients and oxygen, producing enough heat to evaporate some moisture. The temperature can reach as high as 130-170°F.
As the thermophiles gradually consume the available nutrients and oxygen, the temperature will begin to decrease. It is crucial to turn the materials when the temperature drops below 100°F, ensuring that fresh materials, air, and water are introduced into the pile. This turning process helps to maintain the ideal conditions for microbial activity and heat generation.
Over time, the volume of the original materials will decrease, and the compost will become darker and richer. It is important not to add more raw materials unless the composting process is not working properly. Continually checking the temperature, turning the materials, and adding moisture if needed will eventually result in a compost volume that is about 50% of the original.
Once this volume is reached, the temperature will not rise again, indicating that the compost is mature and ready for use. At this stage, the compost can be harvested from the bottom of the pile and used to enhance the fertility of your soil. Following this process and timeline for hot composting will help you create nutrient-rich compost in a relatively short period.
