How to Use Compost: A Beginner’s Guide
How to Use Compost?
To use compost effectively, it is important to ensure that the compost is thoroughly mature before applying it to soil.
Mature compost should resemble dark earth and should not have recognizable ingredients or slimy things.
To deal with woody items that do not break down easily, options include using the compost as is, removing the larger pieces by hand, or screening the entire batch and returning the larger bits to the compost pile for further decomposition.
It is advised not to use compost with a high proportion of uncomposted refuse on nitrogen-poor soil.
Screening the compost can create a light and uniform soil, even with larger items like corn cobs and avocado pits.
A compost screen can be purchased or easily built for efficient use.
Overall, composting is a beneficial practice for enriching soil and promoting plant growth.

Did You Know?
1. Composting not only reduces waste but also helps combat climate change. By diverting organic waste from landfills, composting helps to reduce the emission of methane, a potent greenhouse gas that contributes to global warming.
2. Did you know that adding coffee grounds to your compost can help deter pests? Coffee grounds contain caffeine, which acts as a natural repellent for common garden pests such as snails, slugs, and ants.
3. Contrary to popular belief, it is not necessary to turn your compost pile regularly. While turning speeds up the decomposition process, leaving it to decompose undisturbed can still break down organic materials into rich compost, albeit at a slower pace.
4. Composting can have significant benefits for water conservation. The use of compost in gardens and landscapes helps improve soil structure, enhancing water retention capacity. This means less water is needed for irrigation, as compost-rich soil can better retain moisture.
5. The type of materials you use in your compost can affect the pH of the resulting compost. For example, adding citrus peels can increase the acidity of the compost, making it suitable for acid-loving plants. Conversely, adding materials like wood ash can increase alkalinity, benefiting plants that prefer alkaline soil conditions.
Recognizing Mature Compost
Compost is ready for use when it exhibits certain characteristics that indicate it has fully decomposed. One of the key signs of mature compost is its appearance, which should resemble dark earth rather than rotting vegetables or organic matter. The dark color is an indication that the organic materials have broken down and transformed into rich humus.
Apart from its appearance, mature compost should also feel crumbly and have a pleasant earthy smell. This indicates that the compost has undergone the necessary decomposition process and is now teeming with beneficial microorganisms that will provide essential nutrients to plants. If the compost still has a foul odor or feels slimy, this suggests that it is not yet fully mature and should not be applied to soil.
Testing Compost Maturity
To ensure that compost has reached the desired maturity level, various methods can be employed. The Florida Online Composting Center offers home tests specifically designed for testing compost maturity. These tests typically involve evaluating the moisture content, pH levels, and carbon-to-nitrogen ratio of the compost sample. Through these tests, one can determine if the compost has reached a stable and beneficial state for plant growth.
Additionally, the Ohio State University Extension Office provides detailed information on how to test compost maturity. They offer guidance on conducting simple tests that can assess the readiness of compost for use in gardens or landscapes. These tests often involve examining the temperature, smell, and appearance of the compost to determine its level of maturity.
- Evaluate moisture content
- Measure pH levels
- Assess carbon-to-nitrogen ratio
- Examine temperature, smell, and appearance
It is important to ensure that the compost has reached the desired maturity level before using it to maximize its benefits.
Beware Of Immature Compost
It is crucial to avoid using immature compost, as it can have detrimental effects on plants. Immature compost may contain acids and pathogens that can harm or even kill plants. When the composting process is not complete, organic materials may still have high levels of nitrogen, which can interfere with the growth of plants. Additionally, immature compost may release volatile compounds that are harmful to vegetation.
To minimize the risks associated with immature compost, it is essential to ensure thorough maturity before applying it to soil. This can be achieved by:
- Allowing the compost to reach the desired temperature
- Conducting the necessary tests to assess its maturity level
- Observing its appearance, feel, and smell
By taking these precautions, gardeners can ensure that their plants receive the full benefits of compost without any negative impacts.
Timing Is Key: When To Apply Compost
Timing is crucial when utilizing compost effectively. It is important to determine the appropriate time for application once the compost has matured and reached the desired characteristics.
- Applying compost too early can be ineffective
- Waiting too long may delay the benefits it provides to plants
Hot piles, which are compost piles that undergo a rapid breakdown process facilitated by high temperatures, are typically considered ready when they stop heating up and have been regularly turned. This process usually takes around two to three months.
On the other hand, cool piles, which decompose more slowly, may take up to a year to mature before they are ready for use.
It is important to remember that proper timing is essential for maximizing the benefits of compost application.
Differentiating Hot And Cool Piles
Hot piles and cool piles are two different methods of composting with varying timelines.
Hot piles are made up of well-mixed organic materials with a high carbon-to-nitrogen ratio. They are carefully managed to promote rapid decomposition. The intense activity of microorganisms in hot piles generates high temperatures, which effectively break down the organic matter at a faster rate. As a result of proper management, hot piles can be ready for use within a few months.
On the other hand, cool piles involve a slower decomposition process. They rely on passive methods, where organic materials are left to decompose naturally without frequent turning. Although cool piles take longer to mature, they require less maintenance. It can take up to a year for these piles to fully decompose and be ready for utilization.
To summarize:
- Hot piles:
- Well-mixed organic materials with high carbon-to-nitrogen ratio
- Managed carefully for rapid decomposition
-
Ready for use within a few months
-
Cool piles:
- Organic materials left to decompose naturally
- Slower decomposition process
- Require less maintenance
- Can take up to a year to fully decompose and be ready for utilization
“The hot piles and cool piles refer to different methods and timelines for composting.”
Dealing With Woody Items In Compost
When composting, it is common to encounter challenging items, such as eggshells and woodchips, that take longer to break down completely. However, there are several effective approaches to managing these woody items:
- Use the compost as it is: Accept that larger woody bits may still be present. While this may not be aesthetically pleasing, the larger pieces contribute to soil structure and nutrient retention.
- Remove larger pieces: Handpick the larger woody materials and either repurpose them or dispose of them separately.
- Screen the compost: If a more uniform texture is desired, the entire batch of compost can be passed through a mesh material. This allows smaller, fully decomposed particles to pass through while retaining the larger, unfinished woody materials. The large bits can be returned to the compost pile for further decomposition, and the screened compost can be applied to the soil, resulting in a light and uniform texture.
Note: It is important to choose the approach that suits your specific needs and preferences.
- Ultimately, composting woodier materials requires patience and consideration for the desired outcome.
Conclusion
The process of composting is a valuable tool for gardeners and homeowners seeking to improve the health and fertility of their soil. Recognizing mature compost is vital to ensure its effectiveness when used. Proper testing procedures and understanding the risks associated with immature compost can prevent damage to plants. Timing the application of compost and knowing the differences between hot and cool piles can optimize the benefits derived from composting. Lastly, managing woody items through various methods can promote a more favorable compost texture. By following these guidelines and using compost properly, gardeners can harness the enriching power of “black gold” to make everything grow great.
