Composting is performed at the landscape shop located at the former
Northwest Airlines hangar. The process combines nitrogen from the green materials (
flowers, grass clippings) and carbon from the brown materials (dried leaves and straw).
These materials are turned regularly and eventually break down into decomposed
organic matter known as compost. All of the materials are derived from routine
work at the airport (eg. grass cutting, raking leaves in the fall, recycled flowers).
The materials are added to the compost pile throughout the year.
The compost is used as a soil amendment in the various seasonal color beds
and containers throughout the Airport property.
