Mar 21, 2021 · While the Shannon diversity varied between manure compost types, the diversity of sheep and cattle manure composts were significantly higher compared to pig and chicken manure composts at both composting phases (bacteria: F 1,23 = 12.5, P = 0.002; fungi: F 1,23 = 6.07, P = 0.022, Figures 2A,B).
Manure can be composted in piles or in bins. Bins are best for keeping the manure in a neat heap. As with regular composting, a three-bin system can be useful here. One bin can be used for adding fresh manure, a second for the process to finish and a third for use. A larger size will get hotter, though.
