Quick Answer
Using humanure compost in raised beds requires careful handling and preparation to minimize risks and ensure safety. It's essential to pasteurize the humanure compost to kill pathogens and weed seeds. A 131°F temperature maintained for 3 days can effectively pasteurize the compost.
Handling and Preparation
Humanure compost should be stored in a well-ventilated area, away from children and pets, until it’s ready to use in raised beds. A 3-bay composting system with separate bins for adding materials, aerating, and curing the compost is recommended. The composting process typically takes 1-2 years, depending on factors like temperature, moisture, and carbon-to-nitrogen ratio.
Safety Precautions
To minimize the risk of pathogens and parasites, humanure compost should be pasteurized before using it in raised beds. This can be achieved by maintaining a temperature of 131°F (55°C) for 3 days. It’s also essential to use gloves and a face mask when handling the compost, and to avoid getting it in eyes or mouth.
Application in Raised Beds
Once pasteurized and cured, humanure compost can be applied to raised beds at a rate of 2-4 inches (5-10 cm) per bed, mixed with other amendments like peat moss or coconut coir. The compost should be aged for a few weeks before planting to allow beneficial microbes to colonize the soil. Raised beds receiving humanure compost can expect improved soil structure, increased fertility, and reduced need for synthetic fertilizers.
