COMPOST PREPARATION
Phase I
Compost does not heat up,
remains under 1 40°F.

Undersupplemented.

Check compost formula.
Check Nitrogen content of
raw materials.

Pile too open, airy.

Compress pile sides. Protect
pile from strong winds.

Moisture content too high or

Balance moisture to 70%.

low.

Compost generates no ammonia.

Insufficient pile mass.

Increase total raw materials.

Undersupplemented.

Check compost formula calculations. Check Nitrogen
content of raw materials.
