What is Compost?

Compost is the end product of the decomposition of organic matter, such as food scraps, yard waste, and other biodegradable materials. Through the natural process of aerobic decomposition (using oxygen), microorganisms and detritivores (like worms and insects) break down these materials into a dark, crumbly, earthy-smelling substance that is rich in nutrients and beneficial for soil.

Key Components of Compost

1. Organic Matter:

   • Kitchen scraps (vegetable peels, fruit scraps, coffee grounds).

   • Yard waste (leaves, grass clippings, small branches).

   • Paper and cardboard (uncoated and non-glossy).

2. Carbon and Nitrogen:

   • Carbon-rich materials ("browns"): Dry leaves, straw, cardboard, wood chips.

   • Nitrogen-rich materials ("greens"): Fresh grass clippings, fruit and vegetable scraps, coffee grounds.

3. Moisture:

   • Water is essential to maintain microbial activity. The compost pile should feel like a wrung-out sponge.

4. Oxygen:

   • Aeration is crucial to prevent anaerobic (oxygen-free) decomposition, which can produce unpleasant odors.

5. Microorganisms and Decomposers:

   • Bacteria, fungi, worms, and other organisms break down organic matter into humus, the nutrient-rich substance in compost.
