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.
