materials
• Office and field supplies (e.g., Manila papers, notebooks, ball pens, marking pens, crayons,
shovel or spading fork, bamboo poles, plastic sheets, wood, and feedstuff sacks);
• Organic vegetable fields ready to be applied and vegetable crops already applied with vermicompost
in learning and adjoining fields;

methodology
• Field walks, hands-on, and brainstorming
steps
1. Divide participants in small groups and ask them to conduct field walks and observe presence
of vermi-casts in vegetable area in learning and adjoining fields. Interview other farmers and
list down all observations related to:
5 Dry, shaded, and cultivated vegetable areas;
5 Moist, shaded, and cultivated vegetable areas;
5 Moist, grassy, and cultivated vegetable area;
5 Moist and uncultivated field; and
5 Dry and uncultivated field.
2. Go back to processing area; brainstorm in small groups and present output to big group. Conduct
participatory discussion to allow sharing of experiences among participants and facilitators.
Motivate farmers to share their best experiences in producing and using vermi-compost as
organic fertilizer in organic vegetable production.
3. Develop an improved procedure of producing and using vermi-compost as organic fertilizer in
organic vegetable production.
4. Facilitate each farmer to do hands-on of producing and using vermi-compost as organic
fertilizer by improving the procedure below 66 :
