GUIDELINES FOR PROMOTING EARTHWORM FARMING: A CASE STUDY OF LUNG DEE EARTHWORM FARM, VILLAGE NO. 1 BAN NONG PHONG KHE, KHUAN PHANG SUBDISTRICT, RON PHIBUN DISTRICT NAKHON SI THAMMARAT PROVINCE

Abstract

This study aimed to: 1) investigate the existing conditions, challenges, and local wisdom associated with earthworm farming at Lung Dee Earthworm Farm; and 2) explore guidelines for promoting earthworm farming at Ban Nong Phrong Khao, Village No. 1, Khuan Phang Subdistrict, Ron Phibun District, Nakhon Si Thammarat Province. A qualitative research methodology was employed. The key informants consisted of Mr. Noppadon Maiduang, the owner and operator of Lung Dee Earthworm Farm, who possessed extensive practical experience in earthworm cultivation, as well as 12 local farmers and community members who utilized earthworm castings in agricultural activities. Data were collected through in-depth interviews and participatory observation and were subsequently analyzed using content analysis. The findings revealed that: 1) local wisdom in earthworm farming comprises two principal systems. The first is the open-system approach, which is characterized by convenience, efficient use of space, and cost-effectiveness, making it particularly suitable for beginners. The second is the closed-system approach, which provides greater control over environmental conditions and production quality but requires more complex management practices and higher investment costs. Regarding utilization, earthworms demonstrate significant potential in organic waste management, vermicompost production, and the generation of high-quality liquid biofertilizers. These products contribute to improving soil fertility, enhancing plant growth, and reducing dependence on chemical agricultural inputs. and 2) Future promotion strategies should emphasize collaboration among community members, governmental agencies, and private-sector organizations. Key initiatives include the establishment of community learning centers, the development of participatory knowledge-sharing platforms through community forums and digital media, and the promotion of earthworm farming as both a primary and supplementary occupation. Such approaches can strengthen community self-reliance, increase household income, reduce agricultural production costs, and support sustainable community development.
