Final answer:
Earthworms play a vital role in enhancing soil health and fertility in agriculture. They improve soil structure, promote nutrient availability, and increase water retention. Their activities ultimately result in better crop yields.
Step-by-step explanation:
Earthworms play a vital role in agriculture by improving soil health and fertility. They burrow through the soil, creating channels that help with aeration and water drainage. Their castings, also known as worm manure, are rich in nutrients that enrich the soil. This makes the soil more fertile and promotes plant growth.
Additionally, earthworms break down organic matter, such as dead plant material, into smaller particles. This process, known as decomposition, helps release essential nutrients into the soil that can be readily absorbed by plants. Earthworms also enhance soil structure by binding soil particles together, which improves the soil's ability to retain water and resist erosion.
Overall, earthworms contribute to agriculture by contributing to soil health, fertility, and structure, which ultimately leads to better crop yields.
