A farm that uses solid-liquid separation has multiple uses for the manure solids after in-vessel composting (windrow composting, solid off-farm, and bedding). Should all of that be taken into consideration or should it all be considered as going through the in-vessel composting?

We only have the option to specify 2 management strategies for the solid fraction after SLS, so there isn’t a perfect answer to match the farm’s situation. If we could enter more than 2 strategies, we could capture all 4 of the above and weight them by the amount of time (in-vessel composting, windrow composting, sold off-farm, and bedding) – but since we can only do 2, I would focus on those where the manure spends the most ‘time’ of the year, e.g. bedding and sold off farm.
