Making Fermented Plant Juice


Objective: To gain skills in making and using fermented plant juice in
composting, gardening and livestock production.
Time Req: 30 minutes to prepare materials for fermenting; One month to
ferment; 10 minutes to periodically collect fermented plant juice; 15
minutes to mix and spray fermented fruit juice in gardens, pig pens,
etc.

Materials: 
Machete, ripe fruits (banana, papaya, etc.), brown sugar, scales,
ceramic crock, brown wrapping paper (or newspaper), twine, syringe
pump for collecting the fermented plant juice, plastic bottles or jugs,
backpack sprayer.

Procedure: 
Based on traditional Korean farming, indigenous microorganisms
(IMO) found in fermented plant juices and other materials reportedly
quicken the decomposition process of compost. Many farmers also
claim that supplemental IMO’s help to improve soil fertility when
fermented plant juice solutions are sprayed on fields, as well as to
strengthen the ability of crops to resist pests. There are also claims that
floral differentiation is increased when fermented plant juices are
sprayed on plant leaf surfaces. UHDP has noticed that applications of
fermented plant juice solutions help to reduce odor in and around
livestock pens.

Step 1 – select plant materials to be fermented
 With the help of UHDP personnel, select 1-2 kg of mature
sweet fruits such as pineapple, banana or papaya. Non-sweet
banana stalks or bamboo shoots may be selected for use as
well.

Step 2 – cut up larger plant materials
 Larger items, such as papaya and pineapple fruits, banana
stalks, and bamboo shoots should be sliced into smaller chunks
that will fit through the mouth of a ceramic crock.

Step 3 – mixing with brown sugar
 If sweet fruits are used, thoroughly mix 1 kg of prepared fruit
with 1 kg of brown sugar and place the mixture into a ceramic
crock. If non-sweet plant materials are used (e.g. banana
stalks, bamboo shoots), mix in about 2 kg of brown sugar with
1 kg of prepared fruit and place into an urn.2
Step 4 – fermentation of the materials

 Fasten brown wrapping paper (or newspaper) over the mouth
of the urn. Place the urn in a cool, dry place that’s out of direct
sunlight. Allow the mixture to ferment in the urn for a month,
taking care not to disturb it.

Step 5 – collecting and storing the fermented plant juice
 After a month, a brown fermented liquid will have begun to
collect at the bottom of the urn. This liquid, in which IMO’s
are found, can be sucked out with a long syringe pump, then
stored in a plastic bottle or used directly. Always cover the
mouth of the urn with wrapping paper each time after
collecting fermented plant juice. Also, be sure to store the urn
or stored fermented plant juice in a cool, dry location that’s out
of direct sunlight.
 For practice, extract the fermented plant juice from the bottom
of an urn for either immediate use or for storage.

Step 6 – long-term management of fermenting plant juice
 Given proper storage, the plant-sugar mixture should continue
to ferment over the next few months during which the IMO
liquid can be accessed for use. However, the mixture should
be inspected from time to time. We can tell that the mixture
has expired when the residues in the urn have turned
completely black. However, the presence of a white mold over
the materials indicates that the mixture is still viable.

Step 7 – use of fermented plant juice
 The fermented plant juice can be mixed with water to make a
spray solution for application to plants, field and garden soil,
compost heaps and animal pens at a rate of 1 teaspoon of
fermented juice per liter or 1.5 tablespoons per 20 liters.

 For practice, collect some fermented plant juice from either an
urn or a storage bottle, mix it with water according to
recommendations for use in a backpack sprayer and apply the
solution in the garden or in animal pens.

I'm making research on how to make an alternative solution in a organic farming.  I can use this soon.
