worm castings

Digested soil fertilizer

Worm castings are the excrement of earthworms, prized as a nutrient-rich organic fertilizer.

As worms digest organic matter, they produce castings that improve soil structure and provide plants with readily available nutrients.

Gardeners value them for enriching compost and potting mixes: I add worm castings to my seedling trays.
