Pig Manure Composting & Fermentation
Release date：2018/10/15
There are several points that need to emphasize when starting to compost pig manure commercially:
* The C:N ratio for pig manure is 6:1. So pig manure should be mixed with common carbon rich materials like sawdust, leaves, hay, straw powder, cornstalks, sawdust, wood bran, peanut shells and various plant refuse with the requirement of 6:1 carbon organic matter to nitrogen ratio.
* When creating pig manure compost pile, the pile size should be controlled, neither too small nor too short, which would affect the fermentation. Usually, the pile height and width depends on the choosed compost turner machine (for instance, the maxmium width and height supported by Whirlston windrow compost turner FD300 is 3m and 1.5m), while the length depends on the space of composting.
* Fermentation temperature should be controlled within 65℃because too high temperature would affect the nutrient of pig manure compost.
