earthworm breeding has a good profit. The highest profit per mu of earthworm culture can reach 1 thousand yuan. Compared with planting vegetables and fruits, this is indeed a minority project, which requires certain farming experience. Such an unpopular business needs to find a sales channel in order to find its own way. In a word, the profits of earthworms are considerable, but there are also some risks, among which sales are the most important thing we need to pay attention to. If there is no market and it can't be sold, the economic benefits will be greatly affected. Everyone must consider it carefully.
