Compost
/KOM-post/🪨 Soil Types● Basic
Also known as: garden compost, finished compost
The product of controlled aerobic decomposition of organic materials such as garden waste, kitchen scraps, leaves, and manure. Mature compost is dark, crumbly, earthy-smelling, and rich in nutrients and beneficial microorganisms. It improves soil structure, water retention, drainage, and nutrient-holding capacity. Composting recycles waste into a valuable soil amendment. The process requires balanced carbon-to-nitrogen ratios, adequate moisture, and aeration.
Etymology
Latin compositus (put together), from componere (to arrange)
Example
“Work a 2-inch layer of compost into the top 6 inches of garden soil each spring to improve tilth and fertility.”
