Do Earthworms help plants grow?

Earthworms are among the most important soil dwelling invertebrates. Their activity affects both biotic and abiotic soil properties, in turn affecting plant growth. ... This suggests that earthworms stimulate plant growth predominantly through releasing nitrogen locked away in residue and soil organic matter.

Can Earthworms help keep nutrients in soil?

Earthworms help create humus—a dark brown-black type of soil which holds important nutrients in place for plant growth and use. Earthworms also help create good soil structure; their burrows open up the soil and create aeration and drainage channels.

What does lots of earthworms mean?
