What are the 4 components needed for composting?

The four essential components needed for composting are nitrogen-rich materials (greens), carbon-rich materials (browns), water, and air. Nitrogen sources include kitchen scraps and grass clippings, while carbon sources consist of dried leaves and paper. Adequate moisture helps maintain microbial activity, and air circulation is crucial for aerobic decomposition. Balancing these components promotes efficient composting and results in nutrient-rich compost.
