6. List down all pertinent observations.
7. Present output of small groups to the big group. Conduct participatory discussion to allow
sharing of experiences among participants. Relate abundance of soil organisms (e.g., soil flora
and fauna) to their beneficial activities (e.g., organic matter decomposition, inorganic mineral
transformation, and nitrogen fixation) in organic vegetable production; and
8. Synthesize and summarize output of small groups into one big group output. Draw up
conclusions and recommendation from this exercise.
some suggested questions for processing discussion
❏ What do we mean by soil flora and fauna?
❏ Did you observe beneficial activities of various soil flora and fauna at different soil ecosystems
in learning and adjoining fields?
❏ Do you think there will be differences in performance (e.g., plant growth, development, and
yield) of organically-grown vegetables in soil ecosystems where beneficial activities of soil flora
and fauna were observed? Why?
❏ What factors do you think influenced beneficial activities of soil flora and fauna in different
soil ecosystems?
❏ What do you think is the relationship between abundance of soil organisms (e.g., soil flora
and fauna) and their beneficial activities (e.g., organic matter decomposition, inorganic mineral
transformation, and nitrogen fixation) in organic vegetable productivity?
❏ How do we maintain or enhance abundance of beneficial soil organisms (e.g., soil flora and
fauna)?
