Composting is a manure management option to consider if there isn’t enough land for manure application. Increased cash flows can be obtained from compost sales only if patience and hard work are present. A composting option should be evaluated in the context of the entire manure management system on the farm. For liquid manure systems, composting may require separation of liquids and solids, which will add an extra step and additional cost. Composting can easily be done with manure from shallow or deep-bedded systems. Composting has also been done using liquid manure directly by blending with straw, corn stover or wood waste. This may be a viable option on farms that have manure with higher solids content. If composting is to be done, there are 2 options. If siting a new operation, it makes sense to consider a shallow litter system, followed by composting the manure. For existing operations, consider the overall manure management and reduce the water content of the manure. Composting of the manure following separation is a good option, but there is the idea of a system that does not require separation.
