I never realized how important the earthworm was to our soil.
They are not only good for catching fish. The earthworm is what feeds our soil and gives it the rich nutrient our plants need.
Earthworms also create tunnels in the soil that allow air and water to flow through. The earthworms eat the soil which has decaying matter and digest it. After it is digested through the worm it is released waste called casting. Casting is full of nutrient that plants can use. The casting is great for fertilizer.
