Factors to Consider

When it comes to composting, there are several factors that you need to consider in order to achieve a successful and efficient process. These factors include the compost ingredients, compost bin size, compost temperature, compost moisture, and compost odor. By carefully considering these factors, you can ensure that your composting endeavors are effective and yield high-quality compost.

Compost Ingredients

The key to creating nutrient-rich compost lies in the careful selection of compost ingredients. A good mix of brown materials, such as dead leaves and branches, and green materials, such as kitchen scraps and grass clippings, is crucial for achieving the right balance of carbon and nitrogen in your compost pile. It is recommended to aim for a ratio of roughly 3 parts brown materials to 1 part green materials. By maintaining this balance, you will create an optimal environment for decomposition and encourage the growth of beneficial microorganisms.

Compost Bin Size

Choosing the right compost bin size is another important factor to consider. The size of your compost bin should be determined by the amount of organic waste you generate on a regular basis. If you have a small household with minimal organic waste, a small bin or even a compost tumbler may be sufficient. However, if you have a larger household or generate a significant amount of organic waste, investing in a larger compost bin or even constructing a compost pile in your yard may be necessary. It is important to make sure that your compost bin or pile is large enough to accommodate the amount of waste you generate, as this will ensure that your composting process is efficient and effective.

Compost Temperature

Compost temperature plays a crucial role in the decomposition process. Ideally, the temperature inside your compost pile should range between 120 and 160 degrees Fahrenheit (49 to 71 degrees Celsius). This range of temperatures promotes the growth of thermophilic microorganisms, which are responsible for breaking down organic matter at a faster rate. Regularly monitoring the temperature of your compost pile using a compost thermometer can help you ensure that the conditions are optimal for decomposition. If the temperature falls below the desired range, it may be necessary to adjust the compost pile by adding more green materials or turning the pile more frequently.

Compost Moisture

Proper moisture levels are essential for a thriving compost pile. The moisture content of your compost pile should resemble that of a damp sponge. It should neither be too dry nor too wet. Maintaining a moisture level of around 40 to 60 percent is generally recommended. To achieve this, you may need to periodically add water to the compost pile or cover it with a tarp to prevent excess moisture during heavy rainfall. By keeping a close eye on the moisture levels and making necessary adjustments, you can ensure that the microorganisms within your compost pile have the optimal conditions they need to thrive and break down organic matter.

Compost Odor

While compost should have a natural earthy smell, it should not emit foul odors. If your compost pile has a strong, unpleasant odor, it may indicate that the balance of ingredients is off or that the pile is too wet and lacking proper aeration. To remedy this, you can add more brown materials to absorb excess moisture and assist with aeration, such as dry leaves or wood chips. Regularly turning your compost pile and ensuring it has adequate airflow can help minimize odor issues and create a more pleasant composting experience.

General Guidelines

In addition to the specific factors mentioned above, there are some general guidelines that can help ensure the success of your composting efforts. These guidelines include the minimum turning frequency, optimal turning frequency, and recommended turning practices.

Minimum Turning Frequency

In order to keep your compost pile in good condition and prevent the development of odors and anaerobic conditions, it is recommended to turn your compost pile at least once every two weeks. Turning the pile helps to incorporate oxygen into the compost pile, which is necessary for the decomposition process. By providing oxygen, you create an aerobic environment that promotes the growth of beneficial microorganisms and speeds up decomposition.

Optimal Turning Frequency

While the minimum turning frequency is important for basic maintenance of your compost pile, if you want to accelerate the decomposition process and produce compost more quickly, you can increase the frequency of turning. Ideally, turning your compost pile once a week or even every few days will result in faster decomposition and a shorter composting time. However, it is important to strike a balance between turning the pile frequently enough to speed up the process and giving the microorganisms enough time to break down the organic matter. Overturning can disrupt the microbial activity and slow down decomposition, so finding the optimal turning frequency may require some experimentation and observation based on the specific conditions of your compost pile.

Turning Practices

When it comes to turning your compost pile, there are a few practices to keep in mind. It is recommended to use a compost fork or shovel to gently turn the outer layer of the pile into the center, mixing the materials thoroughly. This helps to evenly distribute the organic matter and ensures that all parts of the pile have access to oxygen. Additionally, as you turn the pile, be mindful of large clumps or chunks of material that might impede aeration. Breaking them up or adding them back into the outer layers of the pile will help maintain the ideal conditions for decomposition. Finally, after turning the pile, consider adding a layer of fresh, nutrient-rich materials on top. This will provide a new food source for the microorganisms and help maintain the high temperature within the compost pile.

Composting Methods

Now that we have explored the general guidelines for composting, let’s dive into the specific methods you can use to compost effectively. The two main methods of composting are hot composting and cold composting. Each method has its own unique considerations and benefits, so understanding the differences can help you choose the method that best suits your needs and resources.

Hot Composting

Hot composting involves creating a large compost pile that reaches high temperatures through the activity of thermophilic microorganisms. This method requires more maintenance and attention, but it can result in faster decomposition and the production of high-quality compost.

Cold Composting

Cold composting, on the other hand, is a more passive method that involves simply piling up organic materials and allowing them to decompose naturally over time. While this method may take longer to produce compost, it requires less effort and is a more hands-off approach for those who prefer a low-maintenance composting solution.

Now, let’s explore each composting method in more detail.

Hot Composting

Hot composting is a method that utilizes the natural heat generated by microorganisms to break down organic matter quickly and efficiently. This process typically occurs in a large compost pile that is carefully managed to maintain optimal conditions for decomposition.

Compost Pile Size

The size of your compost pile is an important consideration when practicing hot composting. For hot composting to occur, the compost pile needs to reach high temperatures, and larger piles are more likely to retain heat effectively. In general, a compost pile should be at least 3 feet high, 3 feet wide, and 3 feet long to ensure sufficient mass and heat retention. However, larger piles, such as those measuring 5 feet by 5 feet by 5 feet or even larger, are even more effective at generating and maintaining high temperatures.

Compost Pile Temperature

To achieve hot composting, the compost pile needs to reach and maintain temperatures between 120 and 160 degrees Fahrenheit (49 to 71 degrees Celsius). These high temperatures are necessary to stimulate the growth of thermophilic microorganisms that thrive in hot environments and accelerate the decomposition process. Monitoring the temperature of your compost pile using a compost thermometer is essential to ensure that it remains within the desired range. If the temperature drops below the recommended range, it may be necessary to add more green materials or turn the pile more frequently to generate additional heat.

Compost Pile Moisture

Maintaining the proper moisture levels in your compost pile is crucial for hot composting. The optimal moisture content for a hot compost pile falls within the range of 40 to 60 percent. If the pile becomes too dry, decomposition slows down, and beneficial microorganisms may become inactive. Conversely, if the pile becomes too wet, it can lead to anaerobic conditions and the production of unpleasant odors. Regularly monitoring and adjusting the moisture content of the pile by adding water or dry materials as needed is vital to create an environment that supports the growth of microorganisms and facilitates the breakdown of organic matter.

Compost Pile Turning Frequency

Turning the compost pile is an essential aspect of hot composting. By turning the pile, you promote aeration and help distribute heat and moisture throughout the compost pile, ensuring that all parts of the pile decompose evenly. Ideally, a hot compost pile should be turned at least once a week to maintain optimal conditions and maximize decomposition rate. However, depending on the temperature and moisture levels of the compost pile, you may need to turn it more frequently or less frequently. Monitoring the pile’s progress and making adjustments accordingly will help you determine the optimal turning frequency for your specific compost pile.

Compost Pile Turning Techniques

When it comes to turning your hot compost pile, there are different techniques you can employ. Some commonly used turning techniques include flipping, layering, and remixing. Flipping involves physically flipping the compost pile using a compost fork or shovel, moving the materials from the outer portions of the pile to the center. This technique helps ensure that all parts of the pile are exposed to heat and oxygen, facilitating the decomposition process. Layering involves adding fresh organic materials on top of the existing compost pile to provide a new food source for the microorganisms. This technique can help maintain the high temperature within the pile and accelerate decomposition. Remixing, on the other hand, involves thoroughly mixing the materials in the compost pile using a compost fork or shovel, ensuring that all parts are well-mixed and exposed to oxygen. Experimenting with these turning techniques and finding the one that works best for your compost pile can significantly enhance the efficiency of your hot composting process.

Cold Composting

If you prefer a more hands-off approach to composting, cold composting may be the method for you. Cold composting is a slower process that relies on natural decomposition without the need for active management or high temperatures.

Compost Pile Size

When practicing cold composting, the size of your compost pile is less critical compared to hot composting. Cold compost piles can be smaller and no specific dimensions are necessary. However, larger piles are still beneficial, as they create more favorable conditions for decomposition and provide a better heat-retaining environment.

Compost Pile Moisture

Maintaining proper moisture levels in a cold compost pile is just as important as in a hot compost pile. Although not as critical as in hot composting, ensuring the pile stays moist is essential for the microbial activity that leads to decomposition. To maintain moisture, the pile should be kept relatively damp but not saturated. Regularly checking the moisture levels and adding water or dry materials when necessary will help create an environment conducive to the decomposition of organic matter.

Compost Pile Turning Frequency

Unlike hot composting, cold composting does not require regular turning. In fact, cold compost piles can be left largely undisturbed, allowing natural decomposition processes to take place without intervention. The decomposition in a cold compost pile is a longer, slower process, and turning the pile is not necessary to maintain the required high temperatures. However, occasional light turning or mixing of the compost pile can be beneficial to improve airflow and aid in decomposition. Performing these actions once every few months or whenever you feel the need to redistribute the materials can help enrich the compost pile and encourage decomposition.

Compost Pile Turning Techniques

While turning techniques are not a central aspect of cold composting, some light mixing or turning can be beneficial. A simple way to achieve this is by using a garden fork or shovel to gently mix and distribute the materials within the compost pile. You can focus on incorporating any dry or undecomposed materials into the rest of the pile and ensuring that the moisture and oxygen are evenly distributed. However, it is crucial to remember that cold composting is a more relaxed, hands-off method, and excessive turning or mixing can disrupt the natural balance of the compost pile. Instead, a gentle approach is preferable to allow the decomposition to occur at its own pace.

Alternative Composting Methods

In addition to hot composting and cold composting, there are several alternative composting methods that offer unique approaches and benefits. These methods include vermicomposting, trench composting, and bokashi composting. Each method presents a different way to compost organic materials and offers solutions for various situations and preferences.


Vermicomposting is a composting method that involves using worms, typically red wigglers, to break down organic matter. This method is ideal for those with limited space or who wish to compost indoors. Vermicomposting not only produces nutrient-rich compost but also produces liquid fertilizer known as worm tea, which can be applied to plants for added nutrients.

Worm Bin Size

When vermicomposting, the size of your worm bin is essential. The bin should be large enough to accommodate the number of worms you have and the amount of organic waste you generate. A general guideline is to have one square foot of surface area per pound of worms. It is also important to provide adequate bedding material, such as shredded newspaper or coconut coir, for the worms to live in and compost. By ensuring that your worm bin is of sufficient size, you create a comfortable and productive environment for the worms to thrive and efficiently break down organic matter.

Compost Temperature

Unlike hot composting, vermicomposting does not rely on high temperatures for decomposition. The ideal temperature range for vermicomposting is between 55 and 77 degrees Fahrenheit (13 to 25 degrees Celsius). It is important to keep the vermicomposting environment within this temperature range to ensure the health and activity of the worms. Placing the worm bin in a suitable location, such as indoors or in a cool, shaded area outdoors, can help regulate the temperature and maintain the ideal conditions for the worms and the composting process.

Compost Moisture

Maintaining proper moisture levels is crucial to the success of your vermicomposting system. The bedding material should be kept moist, similar to a wrung-out sponge, to provide a suitable habitat for the worms and facilitate decomposition. Regularly checking the moisture levels and adding water or dry bedding material as needed will help ensure a moist and hospitable environment within the worm bin. Maintaining the right moisture levels also helps prevent the potential emergence of odors or the growth of harmful bacteria.

Compost Turning Frequency

In vermicomposting, there is no need to turn the compost pile as you would in hot composting. The worms themselves naturally move through the bedding material, consuming and converting the organic waste into compost. As long as the worms are active and the conditions are appropriate, they will continuously process the organic matter in the bin. However, it is recommended to periodically check and gently mix the bedding material to distribute the food waste and prevent any clumping or compaction. This light turning encourages a balanced decomposition process and helps maintain a healthy and productive worm bin.

Trench Composting

Trench composting is a method that involves burying organic waste directly in the soil to facilitate decomposition. This method is particularly useful for those with limited space or who want to compost directly in their garden beds or vegetable patches.

Location Selection

When practicing trench composting, choosing the right location is crucial. The selected area should have loose soil and be easily accessible for burying organic waste. It is essential to avoid burying waste near the roots of plants, as this can interfere with their growth and nutrient uptake. Additionally, consider the proximity to your gardening or planting areas to ensure that the compost will benefit the surrounding plants the most.

Compost Placement

To begin trench composting, dig a trench that is about 12 to 18 inches deep and long enough to accommodate the amount of organic waste you have. As you dig the trench, keep the excavated soil nearby to use later for covering the organic waste. Once the trench is prepared, simply deposit the organic waste into the trench, making sure to spread it evenly. Avoid burying large amounts of food waste in one area, as this may attract pests or lead to an imbalance in decomposition. Instead, distribute the waste throughout the trench to encourage uniform decomposition.

Compost Turning Frequency

In trench composting, there is no need to actively turn the compost as you would in other methods. The decomposition process occurs naturally as microorganisms in the soil break down the organic waste over time. However, it is recommended to occasionally mix or turn the soil surrounding the trench to promote aeration and facilitate the decomposition process. Lightly turning the soil every few weeks or whenever you have additional organic waste to bury will enhance the breakdown of the compost materials and ensure consistent nutrient distribution throughout the soil.

Bokashi Composting

Bokashi composting is a unique method that involves fermenting organic waste using microorganisms. This method is particularly suitable for those who have limited outdoor space or live in urban environments.

Bokashi Bin Size

When practicing bokashi composting, the size of your bokashi bin is an important consideration. Bokashi bins are typically small and compact, making them suitable for indoor use or smaller outdoor spaces. The size of the bin should be determined by the amount of organic waste you generate on a regular basis. It is important to choose a bin that is both large enough to hold the waste but also small enough to fit comfortably in your chosen storage or composting area.

Bokashi Bin Turning Frequency

Unlike traditional composting methods, bokashi composting does not require regular turning. The bokashi bin is a closed system that relies on the fermentation process to break down organic matter. Once the organic waste is added to the bin, it is fermented by the beneficial microorganisms present in the bokashi bran or starter. The fermentation process occurs anaerobically, without the need for oxygen, and turns the waste into a nutrient-rich pre-compost material. The bokashi bin should be sealed after each addition of waste, and turning is not necessary during the fermentation period. The absence of oxygen in the bin creates an environment that is conducive to the growth of anaerobic microorganisms.

Bokashi Bin Airflow

Although turning is not required during the fermentation process, providing proper airflow within the bokashi bin is essential. The bin should have a mechanism to allow excess liquid, known as “bokashi juice,” to drain out. This can be achieved through the use of a spigot or drain at the base of the bin. Ensuring that the bin has adequate ventilation and maintaining the correct balance of air and moisture will help promote the fermentation process and prevent the development of foul odors.

Bokashi Bin Moisture

Maintaining the proper moisture levels in the bokashi bin is important to ensure effective fermentation. The organic waste should be compacted in each layer as it is added to the bin to eliminate excess air pockets. This helps create an anaerobic environment for the fermentation process to take place. Additionally, it is important to sprinkle a sufficient amount of bokashi bran or starter over each layer of waste to introduce the beneficial microorganisms. The bran should be moist but not wet, allowing the microorganisms to multiply and ferment the waste effectively. By balancing the moisture levels and providing the right conditions, you can ensure successful fermentation and the production of high-quality pre-compost.
