堆肥化是有机物的受控生物分解——如食物残渣、花园垃圾和纸张——分解成一种富含营养的土壤改良剂，称为堆肥。它将有机物返回土壤，改善结构、保水性和微生物生命。
关键事实
- Converts organic waste into nutrient-rich soil amendment
- Requires a balance of carbon-rich (browns) and nitrogen-rich (greens) materials
- Moisture and aeration are key to maintaining an active decomposition process
- Finished compost improves soil structure, drainage, and water retention
- Suppresses certain soil-borne diseases and boosts beneficial microbial activity
- Reduces household and garden waste sent to landfill
- Can be done in outdoor piles, bins, or indoor worm farms (vermicomposting)
