How Composting Works
Composting is decomposition — the natural process of organic matter breaking down. Here is the science:
The recipe for compost:
- GREENS (nitrogen-rich): Food scraps, grass clippings, coffee grounds. These are wet and provide nitrogen.
- BROWNS (carbon-rich): Dried leaves, shredded newspaper, cardboard, sawdust. These are dry and provide carbon.
- WATER: Moisture helps microorganisms work. The pile should be damp like a wrung-out sponge.
- AIR: Microorganisms need oxygen. Turn the pile regularly to add air.
The workers: Billions of tiny microorganisms (bacteria, fungi) eat the organic matter and break it down. Worms, insects, and other small creatures help too. They are the real heroes of composting!
The process:
1. You add food scraps and brown materials to the pile
2. Microorganisms start eating and multiplying
3. The pile heats up (compost piles can reach 130-160 degrees F!)
4. Over weeks to months, everything breaks down
5. The result: dark, crumbly, earthy-smelling compost
Compost is often called 'black gold' by gardeners because it is so valuable for growing plants!
