Use of earthworms in the composting process in Guatemala

Credit: Manuel Cano Alfaro (Guatemala)

The photos show the use of nymph as a substrate for the production of the earthworm. The use of worms allows the production of compost and simultaneously stabilizes the presence of heavy metals and some other chemicals which could present in the plants. The role of the earthworm stops at the cleaning process of produced compost and it is not recommended to use the earthworms itself as protein supplement to avoid any bioaccumulation possibility of heavy metals and/or other harmful substances in the tissues of the earthworms. The earthworms are commercially produced and sold to compost producers.
