She is trying to enrich the soil with nutrients.
Why are earthworms are important in soils?
- Enhanced nutritional availability: Earthworms eat on plant debris such as dead roots, leaves, grasses, manure, and dirt. Their digestive system focuses on the organic and mineral components of the food they consume. As a result, their wastes are more nutrient-dense than the soil.
- Drainage improvement: Earthworms loosen the soil and improve the drainage system. Earthworm-infested soils can drain water up to ten times faster than soils without earthworms. Under the effect of rain, irrigation, gravity, lime, and other materials, earthworms dig tunnels in the soil that serve as a pathway.
- Earthworms bind sticky soil particles together in water-stable aggregates, improving soil structure. These also aid in the storage of moisture.
- Increased production: Earthworms improve productivity by 70-80% after a short period of time.
