As they burrow their way through soil, earthworms eat their weight each day in organic materials, such as fallen leaves and decaying grass and other plants. They grind up this material and leave it behind in smaller deposits known as castings. The castings are rich in elements crucial for plant growth; those elements include phosphates, nitrates and potash. Just as important, their burrowing helps to aerate the soil, which allows for better air and water penetration to feed plant roots and creates room for healthy root growth. Their activity also neutralizes the acidity and alkalinity of soil and stimulates the activity of soil microbes.
