After harvesting rainwater, sediment and debris tend to settle at the bottom of the barrel. To dispose of the sediment, it is recommended to compost it since it contains organic matter that can be used as garden fertilizer. Composting sediment can enhance soil quality, improve water retention, and increase the nutrient content of the soil. To compost sediment, mix it with other organic materials such as leaves, grass clippings, and food scraps. The mixture should be turned regularly to promote aeration and decomposition. Composting sediment not only reduces waste but also provides a natural and sustainable way to enrich garden soil.
