composting

Composting is a waste management technique that involves the controlled decomposition of organic matter, such as plant material and kitchen scraps, into a nutrient-rich soil amendment called compost. This process is vital in organic farming, where synthetic fertilizers are prohibited, as compost enhances soil structure, provides essential nutrients, and introduces beneficial microbes.1

The decomposition is carried out by microorganisms, breaking down organic waste and reducing its volume by up to 50 percent. This process can occur in simple piles or specialized bins, with aeration being crucial for efficient decomposition. Properly managed compost piles generate heat, which helps eliminate pathogens and weed seeds. Composting can be done on a small scale for home gardens or on a large scale by municipalities to divert organic waste from landfills. Vermicomposting, using earthworms, is another method that produces rich castings.21
