Earthworms are the unsung champions of the soil.
In healthy ecosystems, they can move up to 10–20 tons of soil per acre each year, continuously mixing and enriching it.
As they tunnel through the ground, they create channels that let air and water reach plant roots. At the same time, they recycle decaying matter into casts that are several times richer in nutrients than the surrounding soil.
These tiny engineers help gardens and farms thrive by stimulating beneficial microbes, improving drainage, increasing drought resistance, and storing carbon in the soil.
Want to support them? Feed the soil with organic matter, disturb it as little as possible, avoid harsh chemicals, and keep it slightly moist.
While exact numbers vary, scientists estimate trillions of earthworms live worldwide, working quietly beneath our feet to keep the planet’s soil alive.
