|Which environment results in faster decomposition rates: aerobic or anaerobic?
|Turn one compost pile periodically, while leaving the other pile to rest.
|Does an increase in surface area result in a faster decomposition rate?
|Shred materials before adding
one compost pile, while adding
materials to the other pile whole.
|Does an increase in nitrogen result in a faster decomposition rate?
|Add nitrogen fertilizer between
layers of compost material in one pile only, or add more nitrogenous material such as grass clippings or food wastes.
|Does atmospheric temperature affect decomposition rate?
|Measure the rate of decompositionin a compost pile in the early fall compared with the winter.
|Does the pile generate heat? How does the temperature change when the pile is turned?
|Using a glove, insert a thermometer deep into the compost pile.
