4. Facilitate each farmer to do hands-on of green leaf manuring using weeds and other crops in
learning field during land preparation, weeding, and hilling-up operations by improving the
procedure below:
5 Before land preparation, weeding or hilling-up operations in learning field, collect all
possible green leaf manure materials (e.g., weeds and other crops) from other fields;
5 Cut or remove all weeds before land preparation or hilling-up operations in learning field;
5 Gather other weeds and trim hedges or plants growing on the sides of terraces and bring
from adjoining to learning field;
5 Incorporate in the soil all weeds gathered, plants and hedges trimmed during land
preparation or hilling-up operations;
5 Take note of all relevant observations and experiences during this activity.
5. 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
❏ Did you observe different weeding and post-weeding practices on organic vegetables and other
plants in learning and adjoining fields?
❏ Did you observe farmers green leaf manuring in their fields? Did they use weeds and other
crops for green leaf manuring?
❏ Did you observe farmers using other green leaf manuring materials? What are these green leaf
manuring materials?
❏ Is green leaf manuring effective as a soil and weed management strategy in organic vegetable
production? When is the best time to do green leaf manuring as a soil and weed management
strategy in organic vegetable production?
❏ Did you observe any innovative green leaf manuring procedures used by farmers as a soil and
weed management strategy in organic vegetable production? What benefits did farmers derive
from green leaf manuring weeds and other crops?
❏ What other cultural management options can you use to complement green leaf manuring as a
soil and weed management strategy in organic vegetable production?
