Composting is the process of turning organic matter into fertilizer that can enrich soil and help plants to grow.
Composting has many benefits. It decreases reduces the methane emissions that come from landfills. Normally, organic matter is broken down by organisms that require oxygen. When it is placed in a landfill, the oxygen supply is cut off as the waste becomes buried. Thus, it is broken down by organisms that do not require oxygen, which releases methane, a greenhouse gas that contributes to climate change.
Composting also reduces food waste, conserves water, and improves soil quality. Using compost as fertilizer can help soil to retain more water, meaning less is necessary to water plants and more can be conserved. Compost contains nitrogen, phosphorus, and potassium, the nutrients that fertilize crops. Compost makes soil more productive, and it can also reduce erosion.
