Vermicomposting is a process that relies on earthworms and microorganisms to help stabilize active organic materials and convert them to a valuable soil amendment and source of plant nutrients. Earthworms will consume most organic materials, including food preparation residuals and leftovers, scrap paper, animal manure, agricultural crop residues, organic byproducts from industries, and yard trimmings. This website provides cooperative extension agents, interested stakeholders and the general public with information and resources to vermicompost organic materials generated by farms, institutions, businesses and households.

The Importance of Vermicomposting Today:

worm.ncsu.edu graphicUp to 75 percent of what is discarded by North Carolina’s communities and businesses are organic materials. Instead of disposing of food scraps, yard wastes, and other organics, the materials can be vermicomposted.  This method of recycling converts organic materials that have traditionally been viewed as waste into a valuable soil amendment for plants and crops. When vermicompost is added to soil, it boosts the nutrients available to plants and enhances soil structure and drainage. Vermicompost has also been shown to increase plant growth and suppress plant disease and insect pest attacks.

Vermicompost products have many applications, including home gardening, landscaping, turfgrass, golf courses, viticulture, DOT projects, use in potting soil for the horticultural industry, and in agriculture. Vermicomposting may also be used to help solve North Carolina’s hog waste problems.
