what is compost used for

Compost is used mainly as a soil amendment and natural fertilizer: it adds nutrients, improves soil structure, helps soil hold moisture, and supports healthy plant growth.

Common uses

• Garden beds and lawns to enrich poor soil.

• Farming and horticulture to reduce reliance on synthetic fertilizers.

• Landscaping and urban agriculture to improve soil health and plant resilience.

• Reclaiming damaged land, covering landfills, and other environmental restoration work.

Why people use it

Compost helps soil retain water, reduces erosion, and encourages beneficial microbes that can suppress some soil-borne diseases.

It also keeps food scraps and yard waste out of landfills, which can reduce methane emissions from decomposing organic waste.

Simple example

A gardener might mix compost into a vegetable bed before planting so the soil becomes richer, looser, and better at holding nutrients and water.

TL;DR: Compost is used to feed soil, help plants grow, improve water retention, reduce waste, and support more sustainable gardening and farming.
