A poultry operation wishes to initiate a composting program to deal with the large volume of manure produced (2,500 kg/d). The chicken manure by itself contains too much nitrogen for proper composting. However, sawdust is available from a nearby sawmill to use as a carbon source.
a) If the blended compost (using 2,500 kg of wet manure) is to
have a desired C:N ratio of 32:1 how much sawdust (give in kg of
dry mass and kg wet mass) needs to be added?
b) The ideal moisture content for a compost pile is 60% (by wet
mass). How many liters of water must be added to the compost
mixture for sawdust?
| Product | Chicken Manure | Sawdust |
| C:N ratio | 10:1 | 225:1 |
| N content (by dry basis) | 6% | 0.2% |
| Moisture Content | 70% | 35% |
a)If we consider manure as NH3 source then the required sawdust(as carbon source) is approximately 658.823 kg
b) amount of water required will be approximately 60049 kg
