Residential Composting: At Home and Educational Materials

What is Compost?

Compost is organic material that can be added to soil to help plants grow. Food scraps and yard waste currently make up 20 to 30 percent of what we throw away, but they could be composted instead. Making compost keeps these materials out of landfills where they take up space and release methane, a potent greenhouse gas.

Benefits of Compost

The use of compost is beneficial in many ways.

  • Improves soil structure
  • Improves water holding capacity
  • Modifies and stabilizes pH
  • Increases Cation Exchange Capacity
  • Provides nutrients
  • Provides soil biota
  • Suppresses plant diseases
  • Binds or degrades contaminants

How do I get started

All composting requires four basic ingredients:

  • Browns - This includes materials such as dead leaves, branches, and twigs.
  • Greens - This includes materials such as grass clippings, vegetable waste, fruit scraps, and coffee grounds.
  • Water – Composting organisms need a moist environment.
  • Air – Air circulation in the pile will allow the composting organisms the oxygen they need to live and keep the pile from producing a foul odor.

 

Basic Instructions

  1. Find an area of your yard that gets at least five hours of sunlight per day for best results. (You can compost in the shade, but it takes a bit longer.)
  2. Make or purchase a composting bin to place in your chosen area. A wire ring of chicken wire works just fine, as does a simple pile.
  3. Find a container with a lid to store your kitchen waste.
  4. Fill the container with your kitchen waste.
  5. Accumulate a large pile of brown leaves or other high carbon material like sawdust to put in your composting bin.
  6. Moisten the leaves to the consistency of a wrung-out sponge.
  7. Periodically, stir the contents of your kitchen-waste container into the pile of leaves.
  8. After about one month to 6-weeks, check the bottom of the pile to look for finished compost -- it will look like mulch and smell like “fresh, good soil.” You can use it immediately as mulch around plants.  If you want to use it as a soil amendment, it is best to sift the large chunks out and let it mature a month or so first.

What Can I Put In My Compost?

Just about any kitchen or yard waste can go into your backyard compost. Dry leaves, shredded newspaper and soiled napkins can also be mixed into the bin. Always cover food waste with leaves, weeds, or paper to avoid attracting bugs.

Educational Materials

If you are a teacher, the US Composting Council has several resources that you can use to educate your students on composting.  Additionally, National Agriculture in the Classroom has a small curriculum

 

Other Relevant Information

Metro Nashville has an excellent publication for backyard composters called Dirt on Composting.

Cornell University's Waste Management Institute also has lots of resources for small-scale composting.
