Why are red worms called farmers friends?

Red worms, commonly known as earthworms, are referred to as "farmers' friends" because they play a crucial role in soil health and fertility. They aerate the soil by burrowing, which improves drainage and root growth, while their digestion of organic matter enriches the soil with nutrient-rich castings. This natural process enhances plant growth and contributes to sustainable farming practices, making them invaluable to farmers. Their presence indicates healthy soil ecosystems, promoting biodiversity and productivity.
