Quick Answer
To turn your humanure compost into a valuable resource, focus on hot composting, using the right carbon-to-nitrogen ratio, and maintaining adequate moisture levels. This involves mixing 1 part humanure with 5 parts "brown" materials and 1 part "green" materials, and monitoring temperature to reach 160°F. Regular turning and aeration are essential for effective decomposition.
Creating a Balanced Mix
To successfully compost humanure, it’s crucial to achieve a balanced mix of materials. Aim for a ratio of 1 part humanure (rich in nitrogen) to 5 parts brown materials (rich in carbon) and 1 part green materials (rich in nitrogen). Brown materials include dry leaves, straw, or shredded newspaper, while green materials include grass clippings, kitchen scraps, or manure from herbivores. This balance facilitates efficient decomposition and microbial growth.
Maintaining Adequate Moisture and Temperature
Proper moisture levels and temperature are critical for composting humanure. Aim for a mix that’s as damp as a wrung-out sponge, and maintain a temperature of 160°F (71°C) for at least 7-10 days. Monitor temperature regularly by inserting a compost thermometer, and turn the pile every 7-10 days to ensure even aeration and decomposition. Insufficient moisture or extreme temperatures can slow or halt the composting process.
Monitoring and Regular Maintenance
Regular monitoring and maintenance are essential for producing high-quality compost from humanure. Use a compost turner to aerate the pile and break up clumps, and add bulking agents like straw or shredded newspaper to absorb excess moisture and odors. Regularly inspect the compost for pests, pathogens, and contaminants, and take corrective action as needed to ensure a safe and healthy final product.
