Earthworms are a sign that you have a fair amount of organic nutrients within your soil. They are indicitive of good growing conditions because they prefer to live in similar conditions that plants like to grow in. The worms also contribute to 'fixing' nutrients for plants to better utilise. The plants in turn give back organic material that worms continue to break down and the cycle thus continues.
