What problems do earthworms cause?

The worms alter the physical and chemical properties of soils, changing the pH, nutrient and water cycles, and disrupting symbiotic relationships between soil fungi and roots (mycorrhizas).

By their activity in the soil, earthworms offer many benefits: increased nutrient availability, better drainage, and a more stable soil structure, all of which help improve farm productivity. Worms feed on plant debris (dead roots, leaves, grasses, manure) and soil. … Nitrogen in the casts is readily available to plants.
