Quick Answer
Store finished compost in a dry, well-ventilated area, away from direct sunlight and moisture, and at a depth of 2-3 feet to maintain its quality and stability.
Storing Finished Compost: Temperature and Depth Considerations
When storing finished compost, it’s essential to maintain the correct temperature and depth to ensure its stability and quality. A pile of finished compost should be at least 2-3 feet deep and 4-6 feet wide to allow for adequate carbon-to-nitrogen ratios and microbial activity. Maintaining a temperature of 131-140°F (55-60°C) for 2-3 days will kill pathogens and weed seeds, ensuring the compost is safe for use. However, temperatures above 160°F (71°C) can lead to the loss of beneficial microorganisms.
Compost Storage Containers and Liners
For long-term storage, it’s recommended to use a covered container or bin with a lid to prevent moisture and contaminants from entering. A durable, waterproof liner such as a geomembrane or a heavy-duty plastic sheet can also be used to line the container and prevent leachate from seeping into the surrounding soil. The container should be designed to allow for adequate airflow to prevent anaerobic conditions, which can lead to unpleasant odors and ammonia production.
Handling and Transfer of Finished Compost
When handling and transferring finished compost, it’s essential to wear protective gloves and eyewear to prevent exposure to potential pathogens. A shovel or pitchfork with a long handle can be used to transfer the compost, and a tarp or bucket can be used to collect the compost and transport it to the desired location. To minimize compaction and maintain the compost’s structure, transfer the compost in thin layers and avoid stepping on the pile.
