- Learn and Improve: Documenting what works and what doesn't helps you refine your techniques and become a more efficient composter.
- Share Knowledge: Well-documented data can be shared with others, contributing to the collective knowledge of composting practices globally.
- Demonstrate Sustainability: If you're composting in a community garden, school, or business, documentation can demonstrate your commitment to environmental sustainability.
What to Document in Your Compost Log
A comprehensive compost log should include the following information:
1. Dates and Times
Record the date and time of each entry. Consistency in timing (e.g., daily or weekly) ensures you capture changes accurately. This is especially important if you are trying different methods or additives.
2. Input Materials (Greens & Browns)
Carefully document the types and quantities of materials added to your compost pile. "Greens" are nitrogen-rich materials, while "browns" are carbon-rich. Strive for a balance. Examples of what to document include:
- Greens: Kitchen scraps (vegetable peels, coffee grounds, fruit rinds), grass clippings, garden waste. Specify the types and approximate volume/weight of each item.
- Browns: Dried leaves, shredded paper, cardboard, sawdust, straw. Again, specify the types and approximate volume/weight.
- Ratios: Estimate the ratio of greens to browns (e.g., 1:1, 2:1, 3:1). This is a crucial factor influencing decomposition.
Example: *October 26, 2023, 10:00 AM: Added 2 kg of vegetable scraps (mostly potato peels and carrot tops) and 4 kg of dried leaves. Estimated greens-to-browns ratio: 1:2.*
3. Temperature
Temperature is a key indicator of the composting process. Use a compost thermometer to measure the temperature at different depths within the pile. Document the location of the measurement. Composting typically proceeds best in thermophilic ranges (131-170°F or 55-77°C). Note that temperature fluctuations are normal. Consider using a digital thermometer with a probe for accuracy.
Example: *October 26, 2023, 10:00 AM: Temperature at 30 cm depth: 60°C (140°F).*
4. Moisture Level
Moisture is essential for microbial activity. The compost pile should be damp, like a wrung-out sponge. Too dry, and decomposition slows down. Too wet, and anaerobic conditions can develop, leading to foul odors. A simple squeeze test can help assess moisture:
- Too Dry: Crumbles apart, no moisture visible.
- Ideal: Feels damp, holds its shape loosely, a few drops of water can be squeezed out.
- Too Wet: Soggy, water drips freely.
Document your assessment of moisture level and any actions taken to adjust it (e.g., adding water, turning the pile). If using a moisture meter, record the reading.
Example: *October 26, 2023, 10:00 AM: Moisture level feels slightly dry. Added 2 liters of water and turned the pile.*
5. Turning/Aeration
Turning the compost pile provides oxygen, which is vital for aerobic decomposition. Document when you turn the pile and how thoroughly it was turned.
Example: *October 26, 2023, 10:00 AM: Turned the compost pile thoroughly using a pitchfork, ensuring all materials were mixed.*
6. Observations
Record any observations about the appearance, smell, and texture of the compost. Note any visible signs of decomposition (e.g., shrinking volume, changes in color, the presence of beneficial organisms). Also, note any problems such as unpleasant odors (indicating anaerobic conditions), excessive flies or other pests, or slow decomposition.
Example: *October 26, 2023, 10:00 AM: Compost is shrinking in volume. The smell is earthy and pleasant. Observed several earthworms. No visible signs of pests.*
7. Amendments (Optional)
If you add any amendments to your compost (e.g., lime, rock phosphate, compost starter), document the type, quantity, and reason for adding them.
Example: *October 26, 2023, 10:00 AM: Added 100g of rock phosphate to increase phosphorus content.*
8. pH Level (Optional)
If you have a pH meter or test kit, you can measure the pH of your compost. The ideal pH range for compost is generally between 6 and 8. Record the pH reading and any actions taken to adjust it (e.g., adding lime to raise pH, adding sulfur to lower pH). This is more relevant for experienced composters or those with specific soil needs.
Example: *October 26, 2023, 10:00 AM: pH level: 7.2.*
Methods for Documenting Your Compost
Several methods can be used to document your composting process:
1. Paper Log
A simple notebook or spreadsheet is a straightforward way to track your data. Create columns for each data point (date, materials added, temperature, moisture, etc.). This method is reliable and doesn't rely on technology, making it suitable for off-grid locations. However, it can be challenging to analyze the data over time.
2. Spreadsheet (e.g., Google Sheets, Microsoft Excel)
Spreadsheets offer more flexibility for data analysis. You can create charts and graphs to visualize trends over time. They also allow for easy sorting and filtering of data. These can be shared electronically with other stakeholders.
3. Mobile Apps
Several mobile apps are specifically designed for composting documentation. These apps often include features such as:
- Data entry forms
- Photo uploads
- Temperature and moisture monitoring integration (with compatible sensors)
- Data analysis and reporting
- Reminders
Examples of apps (availability may vary by region) include:
- ShareWaste (primarily for connecting composters and waste providers)
- Compost Log (various apps, search app stores for current options)
4. Online Platforms
Some online platforms offer tools for tracking and managing composting data, particularly for larger-scale operations (e.g., community gardens, farms). These platforms often provide advanced features such as data visualization, reporting, and collaboration tools.

Global Considerations for Composting Documentation
Composting practices vary significantly worldwide, influenced by climate, available resources, and cultural norms. When documenting your composting process, consider the following global factors:
- Climate: Hot, arid climates may require more frequent watering, while colder climates may necessitate insulating the compost pile. Document how climate affects your composting strategy. For example, in tropical climates, decomposition happens much faster, and the moisture level might be consistently high.
- Local Resources: The availability of different composting materials varies depending on your location. Document the types of materials that are readily available in your area and how you utilize them. In some regions, certain agricultural wastes may be common inputs.
- Composting Methods: Different composting methods (e.g., traditional pile composting, vermicomposting, bokashi composting) require different documentation approaches. Adapt your log to suit your chosen method.
- Regulations: Some countries or regions have regulations regarding composting, particularly for larger-scale operations. Ensure your documentation complies with local regulations. For example, some regions may have restrictions on composting certain types of food waste.
- Cultural Practices: Composting may be deeply embedded in certain cultures, with traditional knowledge passed down through generations. Document any culturally specific techniques or materials used in your composting process.
Troubleshooting Common Composting Problems with Documentation
Careful documentation can help diagnose and resolve common composting problems:
- Slow Decomposition: Review your log to identify potential causes. Are you adding enough nitrogen-rich materials? Is the moisture level adequate? Is the pile being turned frequently enough?
- Unpleasant Odors: Anaerobic conditions are often the culprit. Ensure adequate aeration by turning the pile regularly. Check for excessive moisture. Reduce the amount of greasy food scraps or meat products. Your log can help pinpoint when the odor started and what might have caused it.
- Pest Infestations: Cover food scraps with a layer of brown materials to deter flies. Ensure the compost pile is hot enough to kill fly larvae. If you are seeing a particular type of pest, document it and research appropriate organic control methods.
- Compost Too Wet: Add more brown materials, especially absorbent materials like shredded paper or cardboard. Turn the pile to improve aeration. Cover the pile to protect it from rain.
- Compost Too Dry: Add water gradually, turning the pile to distribute the moisture evenly.
Beyond the Basics: Advanced Composting Documentation
For more advanced composters or those conducting research, consider documenting the following:
- Microbial Analysis: Send compost samples to a lab for microbial analysis to assess the diversity and activity of beneficial microorganisms.
- Nutrient Analysis: Test the nutrient content of your compost (e.g., nitrogen, phosphorus, potassium) to determine its suitability for different plants.
- Seed Germination Tests: Conduct seed germination tests using your compost to assess its phytotoxicity (i.e., whether it inhibits seed germination).
- Water Holding Capacity: Measure the water-holding capacity of your compost to understand how well it retains moisture.
