What is Compost?
Compost is decomposed organic materials. It is a natural soil amendment that helps hold soil together and helps soil hold more water. Composting is an acceleration of the decomposition process, where food scraps are referred to as greens and bulking materials (such as newspaper, dry leaves or shredded paper) are called browns.
Compost contains nutrients plants need and reduces the amount of chemical fertilizers needed, thereby saving you money! With approximately 25% of our landfill bound waste being food waste, compost also reduces the amount of waste that enters our landfills.
Build Your Own Composting System
Outdoor Compost PileConstruct a compost bin out of wire-mesh, wooden pallets or a garbage can. Manufactured compost bins are also available for purchase. Ideal size is approximately a 3 foot cube to promote sufficient aeration. A shaded area will help prevent drying out in summer, and avoid areas that will interfere with lawn and garden activities. As you build your compost pile, alternate materials that are “green” with materials that are “brown.” For example, after layering grass clippings and green leaves, alternate with newspaper and dried leaves. Add your compostable items, water the pile regularly and turn every few weeks to increase aeration. When pile no longer heats after mixing, allow it to cure (stand without mixing) for at least 4 weeks before using the compost.
VermicompostingWorm composting is a method for recycling food waste into a rich, dark, compost. Worm composting allows for year round composting and works well for apartment dwellers and classrooms.
To Build One:
- Begin with a small 10 gallon bin and drill a row of holes along the top edge of the bin and about ten holes in the bottom. Also, drill several holes in one of the lids.
- Take the second bin and put several rocks inside. Then take the other bin that now has holes in it and place on top of the rocks in the second bin. The rocks will prop the inside bin up and allow any extra moisture to drain and collect at the bottom.
- Next take soil, shredded paper, a few food scraps and put in the bin and arrange in a pile in the center of the bin. Cover any food with paper! This is very important to prevent fruit flies or the smell of food in contact with air.
- Then take the worms and add to the bin. Right away you will notice that the worms will start disappearing into the paper and center pile.
- Spray with water until all the paper is moist, not wet!
- Check the bin every few days and add paper and water slowly as needed and add food sparingly. Food scrapes can be added every couple weeks.
