As a initial stage before plantation we need a fertile soil. Earthworm will make your soil fertile and itself plough your land regularly. Earthworms are considered to be the farmers friend. When you avoid using pesticide and avoid ploughing your land, earthworms will start growing in your field. As a initial stage you can buy earthworms from farmers and leave in your field (See the below video for multiplication of earthworm). Earthworm will do everything for your. Agriculture waste such as dry leaves, dead plants, waste vegetables, fruits and cow dung will be food for earthworms.
