A worms job is to eat decaying and composting materials in the soil. Worms dont eat dirt. Instead they create a dirt-like substance called worm castings. The benefits of worm castings to the biological composition of the soil have been established through scientifice research.
Research has concluded that by adding as little as 10% worm castings by volume, seed germination increases over 50%. By adding as little as 20% by volume to potting or garden soil, plant size increases by 48-50%; production of fruit by up to 50%; and size and weight of produce by up to 19%. Similar results were derived from studies done on bedding plants as well. In addition, they found that diseases were significantly depressed. For more information, click here,
