Quick Answer
Wet conditions require extra care when composting humanure to prevent anaerobic conditions and pathogen survival. Aeration and carbon-rich materials are crucial in these situations. Covering the pile and incorporating turn times can also help speed up the process.
Managing Moisture
Composting humanure in wet conditions can be challenging, but there are strategies to overcome this issue. One approach is to increase the carbon-to-nitrogen (C:N) ratio by adding more brown materials, such as straw or coconut coir. Aim for 20-30% carbon-rich content, which will help absorb excess moisture and speed up decomposition.
Aeration and Turning
Aeration is critical in wet composting piles to prevent anaerobic conditions, which can lead to pathogen survival and unpleasant odors. Regular turning of the pile (every 7-10 days) can help maintain oxygen levels and speed up the composting process. Aim for 3-5% moisture content, which will facilitate aeration and decomposition.
Covering the Pile
Covering the compost pile with a breathable material, such as a tarp or a mesh screen, can help manage excess moisture. This will prevent rain from entering the pile and reduce the risk of anaerobic conditions. Aim for a 1-2 inch layer of cover material to maintain aeration and regulate moisture levels.
