Compost Pile Volume Calculator
Compost Pile Volume
Calculate the volume and weight of compost generated from green and brown organic materials, with moisture and carbon-to-nitrogen ratio analysis.
Formula
Pile Volume = Total Material Weight / Density; Finished Volume = Initial Volume x 0.4; C:N Ratio = Weighted average of green and brown carbon ratios
Frequently Asked Questions
What is the ideal carbon to nitrogen ratio for composting?
The ideal C:N ratio for active composting is 25:1 to 35:1. Too much carbon (browns) slows decomposition, while too much nitrogen (greens) causes odor and ammonia loss.
How much does a compost pile shrink?
A compost pile typically reduces to 40 to 60 percent of its original volume as materials decompose, compact, and lose moisture.
