Expand the use of worms to improve agricultural productivity, restore soil health, and reduce food waste.
Vermiculture is the intentional cultivation of worms. In gardens and farms, worms are raised and used to break down organic materials as part of a compost process called vermicomposting. During digestion, beneficial microbes are transferred from worm guts into their manure, called castings. When castings are added to soil or mixed into compost, microbes continue to break down organic matter. Castings are a natural fertilizer, providing essential nutrients. They can be steeped in water to produce compost tea. Vermicompost can prevent plant disease and increase the productivity and carbon content of soils. It can be used to divert food and plant waste from landfills. Certain hazardous wastes can also be treated through vermicomposting. Whether at home, on small-scale farms, or on large commercial vermiculture facilities, composting with worms can reduce methane emissions while regenerating the soil.
