Quick Answer
To maintain temperature in humanure compost during winter, use insulation, cover the pile with a tarp or black plastic sheet, and ensure adequate carbon-rich materials to retain heat.
Insulation and Thermal Mass
Insulate the humanure compost pile with a thick layer of straw, shredded newspaper, or wood chips to prevent heat loss. This insulation will reduce the temperature drop and keep the compost pile at a minimum of 131°F (55°C). Add thermal mass materials like brick, concrete blocks, or ceramic tiles to absorb and release heat, maintaining a stable compost temperature.
Covering the Pile
Cover the humanure compost pile with a tarp or black plastic sheet to retain heat and prevent moisture loss. This will also help to speed up the composting process by trapping the heat and carbon dioxide produced during decomposition. Make sure to weigh down the tarp or plastic sheet with rocks or bricks to prevent it from blowing away in the wind.
Carbon-Rich Materials and Turning
Ensure the humanure compost pile has an adequate amount of carbon-rich materials like coconut coir, shredded newspaper, or wood chips. This will help to retain heat and maintain a healthy composting process. Regularly turn the compost pile to aerate it and distribute the heat evenly. Aim to turn the pile every 7-10 days during winter to maintain optimal composting conditions.
