Vermicomposting is a process that uses worms, like red wigglers, to break down organic materials into a nutrient-rich humus known as castings or vermicompost. The document discusses the vermicomposting process, the types of worms used like red wigglers, how to care for the worms, and the benefits of the nutrient-dense vermicompost produced, which includes increasing soil fertility and plant growth when used in gardens or with potted plants. Vermicompost also contains higher concentrations of nutrients like nitrogen, phosphorus and potassium compared to regular soil or compost.
