KYUSEI NATURE FARMING WITH EFFECTIVE MICROORGANISMS (EM TECHNOLOGY)
1.0 Introduction (Top of Page)
Kyusei Nature Farming was developed in Japan with the objective of producing
food that is safe and free of harmful chemicals and toxic materials. For many
years the practitioners of Kyusei Nature Farming adopted the organic farming
system, with little results to provide adequate food for the majority of the
population.
In the 1980's, Prof. Dr. Teruo Higa introduced the concept of Effective
Microorganisms(EM) to Kyusei Nature Farming. Thus, a group of beneficial
microorganisms were cultured and used as a means of improving soil conditions,
suppressing disease inducing microbes and improving the efficiency of organic
matter utilization by crops. This technology proved to be highly successful, and
thus an international conference was organized in November 1989 in Thailand to
introduce this technology to the Asia Pacific region. At this conference, the
Asia Pacific Natural Agriculture Network (APNAN) was formed.
The primary aim of APNAN is to establish an international network of
scientists in the Asia Pacific region, in order to promote research, education
practices and technologies.
These activities will be based on the principles of Kyusei Nature Farming and
the technology of Effective Microorganisms (EM).
1.1 Ideal Agriculture (Top of Page)
The main theme of Kyusei Nature Farming is to practice an IDEAL AGRICULTURE.
The five principles of ideal agriculture as advocated by Kyusei Nature Farming
are:
- It produces safe and nutritious food to enhance human health.
-
It is economically and spiritually beneficial to both producers(farmers)
and consumers.
- It is sustainable and easily practiced by everyone.
- It conserves our environment.
-
It produces sufficient food of high quality for an expanding world
population.
1.2 USE OF BENEFICIAL MICROORGANISMS IN AGRICULTURE (Top of Page)
Agricultural production begins with the process of photosynthesis by green
plants, which requires solar energy, water, and carbon dioxide. These materials
are freely available. Therefore, it can be defined that "Agriculture is to
produce something from nothing". Althought it sounds good, when observed as an
economic activity, present agriculture has an extremely low efficiency. This is
due to the very low utilization efficiency of solar energy by plants.
The potential utilization rate of solar energy by plants has been estimated
theoretically to be between 10 and 20%. However, the actual utilization rate is
less than 1%. Even the utilization rate of C4 plants, such as sugar cane which
have a high photosynthetic efficiency, barely exceeds 6 or 7% during the maximum
growth period. The utilization rate is normally less than 3% even for producing
optimum crop yields.
Past studies have shown that photosynthetic efficiency of the chloroplasts of
host crop can not be enhanced much further. This means that their biomass
production capacity has reached a maximum. Therefore, the best opportunity for
increasing biomass production is to utilize the visible light, which
chloroplasts can not presently use, and the infrared radiation. These together
account for about 80% of the total solar energy. We should also explore ways of
recycling organic energy contained in plant and animal residues through direct
utilization of organic molecules by plants.
In the presence of organic matter, photosynthetic bacteria and algae can
utilize wavelengths ranging from 700 to 1200 nm. Green plants do not use these
wavelengths. Fermenting microorganisms can also breakdown organic matter,
thereby releasing complex compounds such as amino acids for plant use. This
increases the efficiency of organic matter for crop production Thus a key factor
for increasing crop production is the availability of organic matter, which has
been developed by utilizing solar energy and the presence of efficient microbes
to decompose these materials. This increases the utilization efficiency of solar
energy.
2.0 EFFECTIVE MICROORGANISMS (EM) (Top of Page)
Effective Microorganisms or EM is a mixed culture of beneficial
microorganisms (primarily photosynthetic and lactic acid bacteria, yeast,
actinomycetes, fermenting fungi) that can be applied as an inoculant to increase
the microbial diversity of soils. This in turn, can improve soil quality and
health, which enhances the growth, yield, and quality of crops.
The concept of inoculating soils and plants with beneficial microorganisms to
create a more favorable microbiological environment for plant growth has been
discussed for decades by agricultural scientists. However, the technology behind
the concept of Effective Microorganisms and it's practical application was
developed by Professor Teruo Higa at the University of the Ryukyus in Okinawa,
Japan.
Professor Higa has devoted much of his scientific career to isolating and
selecting different microorganisms for developing beneficial effects on soils
and plants. He has found microorganisms that can coexist in mixed cultures and
are physiologically compatible with one another. When these cultures are
introduced into the natural environment, their individual beneficial effects are
greatly magnified in a synergistic fashion.
EM cultures do not contain any genetically modified microorganisms. EM is
made up of mixed cultures of microbial species that are found in natural
environments worldwide.
2.1 EFFECTS OF EM (Top of Page)
The following are some of the beneficial influences of EM:
-
Promotes germination, flowering, fruiting and ripening in plants.
-
Improves physical, chemical and biological environments of the soil and
suppresses soil borne pathogens and pests.
-
Enhances the photosynthetic capacity of crops.
-
Ensures better germination and plant establishment
-
Increases the efficacy of organic matter as fertilizers.
Due to the above stated beneficial effects of EM, yields and quality of crops
are enhanced.
* EM is not a pesticide and thus does not contain chemicals that could be
construed as such. EM is a microbial inoculant that functions as a biological
control measure in suppressing and/or controlling pests through the introduction
of beneficial microorganisms to the plant environment. Therefore, pests and
pathogens are suppressed or controlled through natural processes by increasing
the competitive and antagonistic activities of the microorganisms in EM
inoculants.
2.2 PRINCIPAL MICROORGANISMS IN EM AND THEIR ACTION IN SOIL (Top of Page)
(1) Photosynthetic bacteria (Phototrophic bacteria)
Photosynthetic bacteria are independent self supporting microorganisms. These
bacteria synthesize useful substances from secretions of roots, organic matter
and/or harmful gases (e.g. hydrogen sulfide) by using sunlight and the heat of
soil as sources of energy. The useful substances comprise of amino acids,
nucleic acids, bioactive substances and sugars, all of which promote plant
growth and development.
These metabolites are absorbed into plants directly and also act as
substrates for increasing bacteria. Thus increasing Photosynthetic bacteria in
the soil enhances other effective microorganisms. For example, VA
(vesicular-arbuscular) mycorrhiza in the rhizosphere are increased due to the
availability of nitrogenous compounds (amino acids) for use as substrates
secreted by Photosynthetic bacteria. VA mycorrhiza increases the solubility of
phosphates in soils thereby supplying unavailable phosphorus to plants. VA
mycorrhiza can coexist with Azotobactor as nitrogenfixing bacteria and enhance
nitrogen fixing ability of legumes.
(2) Lactic acid bacteria
Lactic acid bacteria produces lactic acid from sugars, and other
carbohydrates produced by Photosynthetic bacteria and Yeast. Thus, food and
drinks such as yogurt and pickles have been made by using Lactic acid bacteria
for a long period of time. However, lactic acid is a strong sterilizer. It
suppresses harmful microorganisms and increases rapid decomposition of organic
matter. Moreover Lactic acid bacteria enhances the breakdown of organic matter
such as lignin and cellulose, and ferments these materials without causing
harmful influences caused by undecomposed organic matter.
Lactic acid bacteria has the ability to suppress Fusarium propagation which
is a harmful microorganism causing disease problems in continuous cropping.
Generally, increased Fusarium populations weakens plants. This condition
promotes diseases and also results in the sudden increase of harmful nematodes.
The occurrence of nematodes disappear gradually, as Lactic acid bacteria
suppresses the propagation and function of Fusarium.
(3) Yeasts
Yeasts synthesize antimicrobial and useful substances for plant growth from
amino acids and sugars secreted by Photosynthetic bacteria, organic matter and
plant roots.
Bioactive substances such as hormones and enzymes produced by yeasts promote
active cell and root division. Their secretions are useful substrates for
effective microorganisms such as Lactic acid bacteria and Actinomycetes.
(4) Actinomycetes
Actinomycetes, the structure of which is intermediate to that of bacteria and
fungi, produces antimicrobial substances from amino acids secreted by
Photosynthetic bacteria and organic matter. These antimicrobial substances
suppress harmful fungi and bacteria.
Actinomycetes can coexist with Photosynthetic bacteria. Thus, both species
enhance the quality of the soil environment, by increasing the antimicrobial
activity of the soil.
(5) Fermenting Fungi
Fermenting fungi such as Aspergillus and Penicillium decompose organic matter
rapidly to produce alcohol, esters and antimicrobial substances.
These suppress odors and prevent infestation of harmful insects and
maggots.
Each species of Effective Microorganisms (photosynthetic bacteria, lactic
acid bacteria, yeasts, actinomycetes and fermenting fungi) has its own important
function. However, photosynthetic bacteria is the pivot of EM activity.
Photosynthetic bacteria support the activities of other microorganisms. On
the other hand, photosynthetic bacteria also utilizes substances produced by
other microorganisms. This phenomenon is termed "coexistence and
co-prosperity".
When Effective Microorganisms increase as a community in soils, populations
of native effective microorganisms are also enhanced. Thus, the micro flora
becomes rich and microbial ecosystems in the soil become well-balanced, where
specific microorganisms (especially harmful microorganisms) do not increase.
Thus, soil borne diseases are suppressed.
Plant roots secrete substances such as carbohydrates, amino and organic acids
and active enzymes. Effective microorganisms use these secretions for growth.
During this process, they also secrete and provide amino and nucleic acids, a
variety of vitamins and hormones to plants. Furthermore, in such soils,
effective microorganisms in the rooting zone(rhizosphere) co-exist (symbiosis)
with plants. Hence, plants grow exceptionally well in such soils which are
dominated by effective microorganisms.
This chart
shows the fuctions of Effective Microorgansims in the soil.
3.0 APPLICATION OF EM1 (Top of Page)
Basically, EM can be applied in four ways, namely as EM1 stock solution, EM5
solution, EM Bokashi and as EM fermented plant extract.
3.1 EM1 Stock Solution (Top of Page)
EM1 stock solution can be applied by:
-
Watering into the soil (by watering cans, sprinklers or irrigation systems)
-
Spray onto plants (foliar spray) by sprayer or watering can
3.2 EM BOKASHI (EM fermented organic matters) (Top of Page)
"Bokashi" is a Japanese word which means "Fermented organic matter". It is
made by fermenting organic matter (rice bran, oil cake, fish meal etc.) with EM.
Bokashi is normally found as a powder or as granules. Bokashi has been used by
Japanese farmers as traditional soil amendments to increase the microbial
diversity of soils and supply nutrients to crops. Traditionally Bokashi has been
made by fermenting organic matter such as rice bran by soil from forests or
mountains, which contain various microorganisms.
However, EM Bokashi is fermented organic matter using EM instead of forest or
mountain soil. Thus, EM Bokashi is an important additive to increase effective
microorganisms in the soil. (Details on the preparation of EM Bokashi is
discussed later.)
3.3 EM5 (EM fermented solutions) (Top of Page)
EM5 is a fermented mixture of vinegar, spirits(alcohol), molasses and EM 1.
It is used to spray the plant to suppress pathogens and keep away insect
pests. (Details of EM5 preparation is discussed later.)
3.4 EM Fermented Plant Extract (EM-F.P.E.) (Top of Page)
EM fermented plant extract is a mixture of fresh weeds fermented with
molasses and EM 1. The main effect of this extract is to supply quality
nutrients to crops, and also to suppress pathogens and keep away
insects.
4.0 EM1 STOCK SOLUTION (Top of Page)
Original EM 1 is yellow-brown liquid with a pleasant odor and sweet-sour
taste. The pH of EM 1 should be below 3.5.
If it has a bad smell or foul odor or pH is more than 4.0, the EM1 has
deteriorated. It should not be used.
4.1 USE OF EM1 STOCK SOLUTION (Top of Page)
Original EM1 is dormant. Thus EM1 needs to be activated by the provision of
'water' and 'food'. This is done by adding water and molasses. (Use EM diluted
solution (0.1%) to apply to crops.)
- 1 litre (1000 cc) of water
- 1 cc of EM1
- 1 cc of Molasses or 1g of any sugars
This solution is left for 2-24 hours and sprayed to plants, soil or organic
matter.
5.0 BOKASHI (Top of Page)
Bokashi is equivalent to compost, but it is prepared by fermenting organic
matter with EM. It can be used 3 - 14 days after treatment (fermentation).
Bokashi can be used for crop production even though the organic matter has not
decomposed as in compost.
When bokashi is applied to soil, organic matter can be utilized as a feed for
effective microorganisms to breed in the soil, as well as supplying nourishment
to crops.
5.1 Aerobic Bokashi and Anaerobic Bokashi (Top of Page)
Bokashi is classified as "Aerobic bokashi" and "Anaerobic bokashi" based on
the manufacturing process. The advantages and disadvantages of aerobic and
anaerobic bokashi are as follows:
Aerobic type Advantage: Can be produced on a large scale.
Fermentation period is shorter than in the anaerobic type.
Aerobic type Disadvantage: Energy of organic matter is lost, if temperatures during fermentation is
uncontrolled.
Anaerobic type Advantage: Maintains energy(nutrition) of organic
matter. This condition is similar to silage.
Anaerobic type Disadvantage: Mismanagement causes spoilage.
In Japan, the anaerobic type is popular, but in Thailand the aerobic type
is widely used.
5.2 Materials of Bokashi (Top of Page)
EM can utilize any type of organic matter. For example, the following can be
used as organic matter in preparing Bokashi
Rice bran, corn bran, wheatbran, maize flour, rice husk, bean husk, rice
straw, oil cake cotton seed cake, pressmud, bagasse,chopped weeds, sawdust.
coconut fiber and husks. crop residues such as empty fruit bunches in oil palm,
fish meal. bone meal. dung of any animals, kitchen garbage, sea weed. crab
hells and similar material.
However, rice bran is recommended as an important ingredient of Bokashi, as
it contains excellent nutrients for microorganisms. It is desirable to combine
organic matter which have low and high C/N ratios. Generally the use of at least
three types of organic matter is recommended in order to increase microbial
diversity.
Adding wood or rice husk charcoal, zeolite, kelp, grass and wood ash to
Bokashi is desirable. These porous materials improve soil physical conditions
and nutrient holding capacity. They also act as harbouring points for
effective microorganisms.
5.3 Preparing Bokashi (Top of Page)

* If you do not have molasses, any kind of sugar can be used. Some materials
that can be used are raw cane sugar, juice of any fruits and waste water of
alcohol industries.
** The quantity of water is a guideline. The quantum of water that needs to
be added will depend on the moisture content of the materials used. The ideal
quantum of water is that required to moisten the material, without
drainage.
Preparation
Anaerobic-type
- Mix rice bran, oil cake and fish meal well.
- Dissolve molasses in the water(1 :100). It is easily dissolved in warm water.
- Add EM into the above prepared molasses solution
-
Pour the EM mixture onto the organic matter and mix well. Please pour the EM
dilution gradually and mix well while checking the moisture content. There
should be no drainage of excess water. The moisture content should be about
30-40%. You can check it by squeezing a handful. Once squeezed, it should remain
as a single unit without crumbling. However, on touching it should crumble
easily.
-
Put the mixture thus made into a bag that does not permit air movement (e.g.
paper or polyethylene bag). This is placed within another polyethylene bag
(black vinyl) to prevent movement of air. Close the bag tightly to maintain an
anaerobic condition. This is placed away from direct sunlight.
-
Temperate zone fermenting period: More than 3-4 days in the summer, more than 7-8
in the winter (In winter, put the container in a warm location to hasten
fermentation), and more than 3-4 days in the tropics.
The Bokashi is ready for use when it gives a sweet fermented smell. If it
produces a sour and rotten smell, it is a failure.
-
Anaerobic Bokashi should be used soon after preparation. If storage is
required, spread it on a concrete floor, dry well in the shade and then put into
vinyl bag. Note: Please prevent rodent or other pest attacks.

-
Put the mixture made above on a concrete floor, and cover with gunny bag,
straw mat or similar material. Avoid exposure of this material to rain.
-
Under aerobic conditions, bokashi ferments rapidly. Thus the temperature
increases. Ideally, the temperature should be kept around 35-45°C. Thus,
please check temperature regularly using a normal thermometer. If the
temperature rises beyond 50°C, mix the Bokashi well to aerate it.
-
Temperate zone fermenting period: More than 3-4 days in the summer,
more than 7-8 days in the winter and more than 2-4 days in the tropics.
It is ready for use when it gives a sweet fermented smell and white mold is observed. If it has a
sour and rotten smell, it is failure.
-
This Bokashi is best used soon after preparation. If storage is required,
spread it on a concrete floor, dry well in the shade and then put into vinyl
bag. Please prevent rodent or other pest attacks.
The efficacy of Bokashi made at temperatures above 50°C is 50% lower than that made at a lower temperature. This
is due to the loss of heat energy at high temperatures.
*Please practice preparing bokashi several times. The key of preparing good
bokashi is to know suitable moisture content and temperature of bokashi through
practice.
It is recommended that you join the EM technology workshop to learn the
process.
5.4 Using Bokashi (Top of Page)
In general, apply Bokashi 200g per 1 square meter on the top soil, when
enough organic matters has been applied.
You can apply more (maximum 1 kg per 1 square meter), when soil is poor or
as little organic matter.
6.0 EM5 (Also known in Japan as Sutochu) (Top of Page)
EM5 is a non-chemical insect repellent and is non toxic . EM5 is used to
prevent disease and pest problems in crop plants. It is usually sprayed onto
plants at a dilution of 1/500 -1/1000 in water. It is mainly used to repel
insects by creating a sort of barrier. EM5 could also control insect
populations. EM5 carried by insects to places of food storage could
"contaminate" the stored food. The process of fermentation that takes place in
the food due to EM5 makes it non-edible to insects, thereby diminishing
populations.
In making EM5, ingredients may vary. A standard set of ingredients is listed
below. However, to make effective EM5 for more persistent pests, more organic
materials should be added (organic materials that has a high quantum of
antioxidants such as garlic, hot peppers, aloe, neem leaf, pruned green fruits,
and grass) which are considered to be of medicinal value. When using such
materials, they should be chopped or mashed in a mixer. Some or all of the
materials may be used in making EM5.

* Well water preferred since tap water is chlorinated.
** Natural vinegar is better than artificial acids
*** Whiskey or Ethyl alcohol could be used.
Items needed in making of EM5:
A large pot may be used to initially blend all of the ingredients. Plastic containers are required to store the EM5 along
with a funnel to pour the EM into the containers.
Preparation
-
Blend the molasses with water, make certain that it has been completely
dissolved. You may use warm water for quick dilution of molasses.
-
Add vinegar and distilled spirit, followed by EM1.
-
Pour the mixed solution into a plastic container which can be shut tightly
(A glass container should not be used). Remove excess air in container to
maintain anaerobic conditions.
-
Store the bottle in a warm place (20-35°C), away from direct sunlight.
-
When container is expanded by the fermented gas, loosen the cap of the
container to release gas. Shut it tightly again.
The EM5 is ready for use when the production of gas has subsided. The EM5
should have a sweet smell (Ester/alcohol).
Storage:
EM5 should be stored in a dark cool place, which has a uniform temperature.
Do not store in the refrigerator or in direct sunlight. EM5 should be used
within three months after preparation.
6.2 Using EM5 (Top of Page)
-
Spray EM5 diluted in water 1/500-1/1000 to wet the crop.
-
Start spraying after germination, before pests and diseases appear.
-
Spray in the morning or after heavy rains.
- Apply EM5 regularly.
Since EM5 is not a pesticide, germicide or a harmful chemical, the
application method is different from other agrochemicals. Chemicals are used to
solve a problem forcefully and quickly and are applied at specific intervals.
EM5, on the other hand, should be applied from the time of planting before the
development of any disease or pests. If this is not done and diseases or pests
appear, EM5 should be sprayed daily until the problem disappears.
Application can be done once - twice a week with a direct spray onto the
plants. Direct spraying on harmful insects should reduce populations leading to
eventual disappearance. A thorough spraying to the plant ensures good
results. Continuous or regular sprayings ensure that harmful insects which may
have escaped or are recent additions will be affected by the EM5.
EM5 works over time. Thus regular applications brings out the best results.
Although chemical applications may give rapid results, it may be harmful to
plants and soil. The long term effects may be disastrous not only to the
environment but also to the farmer's economic condition and health. EM5 has no
adverse effect even with excessive applications. In contrast, EM5 may enhance
the plant's strength through the absorption of EM and therefore increase the
level of antioxidation (that is, the ability to suppress disease, pest
infestation, and overcome any debilitating factors.). Although EM5 may take time
to create the best condition depending on soil and type of crops grown, it will
benefit the environment, the soil, the plant cultivated, and the economic status
of the farmer.
The upliftment of the economic status occurs as EM5 can be made easily and
heaply. Over the long term, less EM5 (costs for the material to make EM5) is
needed since the soil conditions change. This ensures a healthy and strong crop
to protect itself from disease and pests. The post-harvest crop residues
incorporated back to soil as a pre-treatment before the next season is
recommended and, additionally, the use of EM5 would help in the suppression of
diseases and pests that would be recycled back into the next crop.
EM5 contains EM l - therefore it contributes to the beneficial effects that EM 1
increasing yield and quality of the crop. Thus, less expense is incurred on
fertilizers and no cost would be expended on agricultural chemicals.
7.0 EM FERMENTED PLANT EXTRACT (EM-F.P.E.) (Top of Page)
EM fermented plant extract is prepared by using fresh weeds and EM1.
EM-F.P.E. includes organic acids, bioactive substances, minerals and other
useful substances from weeds. The production cost of EM-F.P.E.. is very low,
because of the use of weeds.

8.0 EM1 IN CROP PRODUCTION (Top of Page)
8.1 RICE (Top of Page)
[Autumn treatment in temperate zones.] (After harvest in the tropics)
After harvest, add all crop residues (rice straw and rice husk) to the field,
and apply 30-150kg/ 10a of Bokashi and 500 - 5000L/10a of EM diluted solution (1
:1000) (1-10L/l0a of EM stock solution).
[Raising of seedling]
To hasten germination and prevent diseases, soak rice seeds into EM diluted
solution (1:1000) until seeds are enlarged. It is preferable to change the
solution daily. During raising of seedling, apply EM with water( 1:1000) total
4-5 times. To prevent pest and disease, spray EM5(1:500) to seedlings several
times.
[Spring treatment - for temperate zones.]
At plowing, apply 30-150kg/ba of Bokashi and 50 - 5000L/10a of EM diluted
solution(1 :1000) (1 - 10 L/ 10a of EM stock solution).
[Before and after planting rice seedling]
At puddling, apply 1-10L/ 10a of EM. High concentration (1:50-1:100) can be
acceptable, because the rice field is flooded. 10-15 days after
transplanting, apply 500-1000L/10a of EM diluted solution(1:1000)(1-2L/10a of EM
stock solution), before intercultivation and weeding.
[Growing period]
While observing growth, apply Bokashi(30-50 kg/ 10a) as supplementary
fertilizer. Spray 500-5000L/ 10a of EM diluted solution( 1:1000) (1-10L/10a of
EM stock solution) every 1 or 2 month. Also spray EM5(1 :500) regularly. A
total of 3 - 6 applications of EM and EM5 is required up to harvest.
Weeding in Rice fields (without herbicides)
-
The principle of suppressing weeds by EM
Microorganisms (particularly lactic acid bacteria) in EM produces organic
acids such as lactic acid and other bioactive substances when applied with
organic mater to the soil. These organic acids and bioactive substances break
the dormancy of seeds. They also act on perennial weeds like a rotary
cultivator, and obstructs callus formation, which results in fermented
decomposition of the tubers and roots. By this action weeds are sprouted by
force after tilling in autumn or rough puddling. These weeds just sprouted can
be suppressed at the final puddling, in order to cut down the number of weeding
after planting.
Lactic acid bacteria begins activity at a ground temperature above 5°C. The higher the ground temperature, the more vigorous the
action. Weeds start sprouting at 10 – 15°C. Their action becomes more vigorous with raised temperatures. A temperature greater
than 18°C is required to hasten germination. Therefore conditions are controlled to ensure that lactic acid bacteria works until the
temperature rises.
-
EM treatment in autumn
Spray 1-10L/ 10a of EM stock solution after harvest. This treatment should be
carried out as soon as possible after harvesting rice plants in order to have a
higher ground temperature (over 18°C) for a longer
time. Weeds which sprout in the year can not survive the coming winter, and they
die. For a rice field that could be flooded in winter, a state of flooding gives
a greater effect.
-
EM treatment in spring
Spray 1-1 0L/ 10a of EM stock solution with molasses at rough puddling(depth
of 15-20cm). Let water into the field as soon as possible when the ground
temperature is around 10°C, and puddle roughly. Keep
water from leaking to increase both the ground and water temperature. Then flood
shallowly, and keep the ground temperature >15°C
for more than 20 days. A longer flooded period and higher ground temperature
hastens germination of weeds. After confirming the emergence of main weeds, do
the second puddling(final puddling). This time, puddle the outer side (around 5
cm deeps) to dig up both weeds just sprouted and seeds. Let water into newly
puddled field and wash them out. To avoid pushing them out to the lower rice
fields, pick them up at the water outlet by using cheese cloth or some nets.
The sprouting condition depends on species of weeds. It is important to know
the characteristic of the weeds germinating in your rice field.
8.2 UPLAND FIELD CROPS (Top of Page)
[Preparation of soil]
1-2 months before seeding or transplanting, apply 30-200kg/ 10a of Bokashi
and EM diluted solution (1 :1000) (1-10L/10a of EM stock solution) and plow the
field (In the tropics, bokashi can be applied 2-3 weeks before seeding). After
plowing, mulch field with rice straw, hay or a vinyl sheet. The mulching is
effective to keep soil moisture (i.e. help EM to increase), arid to control
weeds.
[Raising of seedling]
Prepare a good soil for raising seedling with Soil Bokashi. (*See Page
27). Soak seeds (such as seed potatoes) in an EM diluted solution (1 :1000)
for approximately 30 minutes to coat seed with EM. This inoculates seed with
EM. After seeding, water with EM (1:1000-2000). Then spray EM5 (1:1000) to
prevent pests and diseases 1-2 times a week. For seedlings purchased (pot
seedlings), transplant after sprinkling a EM diluted solution (1:1000) 2-3 times
instead of flooding.
[Before and after transplanting (seeding)]
At 3-7 days before planting (seeding), apply an EM diluted solution (1:1000)
(1-10L/10a of EM stock solution). After transplanting, until roots develop,
apply an EM diluted solution (1:1000 - 1:5000) until the field is flooded. The
volume of EM stock solution you can use this time is not fixed. Dilute it
appropriately according to the volume of water required for flooding.
*Bokashi should be applied at least 7-15 days before seeding or
transplanting. Too much Bokashi might cause problems.
[Growing period]
Depending on the crop, apply an EM diluted solution (1:1000) (EM stock
solution 1-10L/10a/one time) every 1 week for 1 month. Increased applications
will not cause any problem, but will be more effective. If it is expensive,
effectual measures should be recommended. At the beginning of the growth
period, increase the number of times of application by shortening spray
intervals. If the growth is favorable, apply at longer intervals.
For prevention of pests, EM5 should be sprayed on the leaves regularly at 7 -
14 days intervals. Addition of molasses or juice of Aloe(0.1%) as sticker into
EM5 increases effectiveness. Please do not spray EM5 at a dilution less than 1:
500. Apply Bokashi as additional manure, while observing crop growth. Do not
apply too much Bokashi at a time. Pay attention not to put Bokashi over the
crops directly, apply Bokashi around the crops.
Never use EM4 and 5 solutions diluted less than 1:500. Concentrated solution
could cause a physiological problem or yellow spots on the leaves, especially in
dry seasons, because of the pH of EM.
[Together agricultural chemicals] (We do not recommend to use these
chemicals)
Agricultural chemicals, especially fungicides (soil disinfectant) reduce the
effect of EM by half. After applying these chemicals, try to spray EM5 days
later.
[Harvest]
Harvest only necessary parts, and return all crop residue to the soil.
Damaged and diseased plants could also be added into the soil. EM is applied as
a diluted solution(1 :1000) with Bokashi. Mulch with rice straw or other
material. Seeding or transplanting could be carried out 14 days - 1 month
after this treatment.
In case of non-tillage culture, start seeding or transplanting between crops
before harvest.
8.3 ORCHARD CROPS (Top of Page)
[Raising of seedling]
It is very important to select suitable species for the environmental
condition and management regimes of your orchard. It is also important to raise
high quality and healthy seedlings using EM, as it costs to replant fruit
trees.
[Before and after planting]
Make the planting hole and put Bokashi and organic matter. After planting,
mulch with rice straw or fallen leaf and water with EM (1:1000).
[Growth period]
Apply EM diluted solution (1:1000) (1-10L/10a of EM stock solution) and
Bokashi (200g - 500g/a square meter) regularly. Spray EM5 (1:500-1:1000)
regularly to prevent pests and diseases.
[After harvest]
Apply EM diluted solution (1:1000) (1-1 0L/ 10a of EM stock solution) and
Bokashi (200g - 1kg/a square meter).
[Sod culture system]
Cover ground with leguminous or graminaceous cover crops. Mow several times a
year and use the cuttings as a mulch. This system can prevent soil erosion,
increase organic matter in soil and improve soil aggregate structure. Alternate
row sod systems or mulch-sod Systems are recommended.
[Mulch with EM]
Grass Mulch is an important technique in nature farming. The good points of
Mulch are as follows: To prevent soil erosion, to keep soil moisture, soil
temperature and maintain a good environment for EM, to suppress weed, improve
soil physical conditions by providing organic matter. To provide nutrients
(particularly water soluble potassium) to crops. Always try to mulch and
apply Bokashi or EM diluted with molasses on the mulch.
This manual presents basic information. Application depends on soil and climate
conditions, and culture such as green house or open air cultivation. The values
on this manual should be used only as a basic reference.
9.0 EM1 IN ANIMAL PRODUCTION (Top of Page)
9.1 Effects of EM1 on livestock (Top of Page)
- Suppresses the foul smell on livestock barns and septic tanks
- Decreases numbers of flies and ticks.
- Improves animal health
- Decreases the stress of animals.
- Improves meat quality.
- Improves fecundity.
- Improves animal dung quality. (produces good manure)
9.2 APPLICATION OF EM1 (Top of Page)
- Add EM Bokashi into feed of animals.
- Mix EM1 into drinking water.
- Spray EM1 multiplied solution on to the livestock barn.
- Sprinkle EM Bokashi on the bedding for animals.
- Put EM1 into septic tanks.
[Add EM Bokashi into feed of animals]
Prepare edible Bokashi and give to animal as additive feed. This Bokashi
improves microflora in intestines. As the result, health of animals is improved
and the bad smell of dung is suppressed.
Preparation
[Materials]
|
Rice Bran
|
100 litres
|
|
Wheatbran*
|
100 litres
|
|
Molasses
|
200 cc
|
|
EM1
|
200 cc
|
|
Water*
|
20 - 30 Litres
|
* Corn flour can also be used as a material.
** The quantity of water is a guideline. The quantum of water that needs to
be added will depend on the moisture content of the materials used. The ideal
quantum of water is that required to moisten the material, without drainage.
- Mix rice bran and wheat bran well.
- Dissolve molasses in the water (1:100). It is easy to dissolve molasses in
warm water.
- Add EM1 into the above prepared molasses solution
- Pour the diluted EM mixture onto the organic matter and mix well. Please
pour the EM dilution gradually and mix well while checking the moisture content.
There should be no drainage of excess water. The moisture content should be
about 30-40%. You can check it by squeezing a handful. Once squeezed, it should
remain as a single unit without crumbling. However, on touching it should
crumble easily.
- Put the mixture thus made into a bag that does not permit air movement (e.g.
paper or polyethylene bag). This is placed within another polyethylene bag
(black vinyl) to prevent movement of air. Close the bag tightly to maintain an
anaerobic condition. This is placed away from direct sunlight.
- The fermenting period is: In the temperate zone: In summer more than 3-4
days. In winter more than 7-8 days. In winter, put the container in a warm location to hasten fermentation.
In the tropics: more than 3-4 days. If anaerobic conditions are not maintained, the temperature increases.
Ideally, the temperature should be around 35-45°C. Thus, please check temperature regularly using a normal thermometer. If the
temperature rises beyond 50°C, mix the Bokashi well to
aerate it, and put into polyethylene bag (black vinyl) and close it to maintain
anaerobic conditions. The Bokashi is ready for use when it gives a sweet fermented smell. If it
produces a sour and rotten smell, it is a failure.
- The Bokashi should be used soon after preparation. If storage is required,
spread it on a concrete floor, dry well in the shade and then put into vinyl
bag. Please prevent rodent or other pest attacks.
Application
1) Mix the bokashi (1-5% of feed) into feed, or sprinkle the bokashi on feed
everyday.
2) Mix EM1 into drinking water.
EM improves microflora in intestines of animals. As the result, health of
animals is improved and also the bad smell of dung is suppressed.
Application
Put EM 1 in the drinking water for animals (1:1000 - 1:5000).
3) Spray EM multiplied solution on livestock barns.
Bad smells in barns and animal diseases are caused by increasing harmful
microorganisms. These produce harmful substances and toxins such as ammonia,
hydrogen sulfide, tori-metiru-amin. EM suppresses the increase of harmful
microorganisms. Thus, the environment of the barns and animal hygiene are
improved.
Preparation

* Well water is preferred since tap water is chlorinated.
- Blend the molasses with water, make certain that it has been completely
dissolved. You may use warm water for quick dilution of molasses.
- Pour the mixed solution into a plastic bucket or drum which can be shut
tightly.
- Store the bucket in a warm place (20-35°C), away
from direct sunlight. It is ready for use 1-2 days later. However, it should be
used within 3 days, after mixing.
Application.
Spray on livestock barn by sprayer. (spray onto floor, walls, ceiling and
drain.) or use as water for washing. Splashing EM solution on animals does not
cause problems. However, in the winter do not spray animals with EM
solutions.
Spray 1-2 litres per square meter every 3-7 days. When bad smell is
suppressed, the number of spray can be decreased.
In case of treading style beds such as in cattle pens, applying this EM
solution in rainy season or winter may cause excess humidity. In such case, use
EM Bokashi (show following) instead of this EM multiplied solution.

Preparation is the same as for "EM Bokashi for animals"
Application
Sprinkle about 50g (a handful of bokashi) per 1 square meters on the bed
every 3-7 days. Once the bad smell is lessened, sprinkle it at longer intervals
(every 2 weeks - 1 month). Consumption of the sprinkled bokashi on the bed does
not cause problems.
5) Put EM1 into septic tanks.
By adopting application methods 1 to 4, EM is fixed in excreta of animals
(manure). Fixed EM utilizes excreta actively, and suppress the work of harmful
microorganisms. As the result, the bad smells of septic tanks are reduced. The
sludge and scam in septic tanks are decreased. Putting EM into septic tanks
increases these effects much more.
Application
Put EM1 stock or EM1 multiplied solution into septic tank (1% of total water
amount in tank) every 1-2 weeks. For example, put 10 litres of EM 1 multiplied
solution into 1 ton tank.
10.0 EM1 IN FISH CULTURE (Top of Page)
EM1 is useful for fish and prawn culture, because it improves water
quality.
Application
Put EM1 into the pond. (0.01% of total water in the pond)(1:10000) every
month. Please check the odor of water regularly. If the bad smell is not
suppressed, put EM1 at shorter intervals.
Mixing "EM bokashi for animals" into feed for fish (1-5% of feed) is very
effective in raising the productivity of fish farms.
11.0 IMPORTANT ASPECTS OF USING EM1 (Top of Page)
(1) EM is a living thing
EM is a living entity. Therefore, EM is completely different from chemical
fertilizers or agrochemicals. EM does not work when applied in the same method
as chemical fertilizers or agrochemicals. It is important to note that EM
increases population of beneficial microbes in the soil.
(2) Use good quality water
It is important to use good quality water when watering crops, diluting EM 1,
preparing Bokashi and EM5. Using polluted water (high BOD, Low DO) causes infection of pests and
diseases, reduction of yield and crop quality. If you can not get good quality water,
please filter it by charcoal or EM ceramics.
(3) Storage of diluted solution
It is desirable to utilize diluted EM1 solutions within 3 days.
(4) Storage information
Store of EM1 - up to 6 months in a closed container, in a cool and dark
place, (Please do not store in refrigerator). Check smell if in doubt. EM 1
always has a sweet and sour smell. If smell is foul, do not use it. After the cap
of bottle is opened and air comes in, a white membrane may be observed on the surface of EM1. This is yeast and does no cause
a problem.

APPENDIX 3: PREPARATION OF EM1 SECONDARY STOCK SOLUTION (Top of Page)
If you cannot get sufficient EM1 stock solution for your land, you can
multiply available EM1 stock solutions. This secondary EM1 stock solution can be
used instead of the original EM1 stock solution. However, this multiplied EM1
(EM1 secondary stock solution) is inferior to original EM1 (EM1 stock solution)
in quality.
Storage period of EM1 secondary stock solution is obviously shorter than the
original EM1 stock solution.
Material
|
Water (without chlorine)
|
100 litres
|
|
EM1
|
5 litres
|
|
Molasses
|
5 litres (or 5 kg brown sugar)
|
(2) Preparation
- Mix EM1 and Molasses well in the water.
- Pour the mixture into a clean plastic container or drum, which can be shut
tightly (A glass container is not applicable.) and store at the ambient
temperature.
-
After 3-10 days, when pH is below 3.5, it is ready for use.
* It is desirable to use this secondary solution as soon as possible. It can
be stored for 1 week under air tight and shady condition.
* DO not multiply the third EM1 stock solution from EM1 secondary stock
solution, because it is very difficult to prevent contamination. The balance of
microorganisms is changed, and the efficacy is lost.
APPENDIX 4: SOIL CLASSIFICATION ON THE BASIS OF MICROBIAL ACTIVITY (Top of Page)
(1) Disease-inducing soil
The percentage of Fusarium in all fungi is high (more than 15 - 20%) in this
soil. When raw organic matter containing high nitrogen is applied, this soil
produces a foul odor. Maggots develop in the soil together with many harmful
insects. Pest and disease infestation is high with significant damage to the
crops.
Therefore, applying raw organic matter is harmful for crops in this
soil. Application of raw organic matter hardens the soil. The soil physical
conditions deteriorate. In case of rice fields, gas is generated. Application of
high quantities of chemical fertilizer and/or agricultural chemicals leads to
the development of this type of soil.
(2) Disease-suppressive soil
Microorganisms which produce antibiotic substances exist in this soil. Thus,
soil borne diseases do not develop easily. As Microorganisms such as Penicilium,
Tricoderma, Streptamyces are active, the percentage of Fusarium in all fungi is
low (less than 5%) in this soil. When raw organic matter containing high
nitrogen is applied to such soil, foul odors do not develop. The soil has the
fresh sweet smell of mountain soil after decomposition. Soil aggregation and
permeability are improved. On cultivation, pest and disease infestation is very
low, but the yield is not so good. If this soil links up with a "Synthetic
soil", productivity is enhanced.
(3) Zymogenic soil
This soil primarily contains zymogenic microorganisms such as lactic acid
bacteria and yeasts. When raw organic matter containing high nitrogen is
applied, this soil develops an aromatic fermented smell. The populations of
fermentable fungi such as Aspergillus and Rhizopus are increased. The percentage
of Fusarium in all fungi is low (less than 5%) in this soil. The water-stable
soil aggregate is high, and the soil becomes soft. Thus the solubility of
inorganic nutrients enhances. The presence of amino acid, sugars, vitamins and
other bioactive substances is increased in this soil, thereby promoting growth
of crops.
(4) Synthetic soil
This soil contains microorganisms such as photosynthetic, nitrogen fixing
bacteria. Under stable soil moisture conditions, the soil quality is enhanced
by addition of small volume of organic matter. The percentage of Fusarium in all
fungi is low in this soil. This soil often links up with a "disease-suppressive
soil"
Zymogenic-synthetic soil
When "Zymogenic-soil" and "Synthetic soil" are linked, it becomes an ideal
soil for crop production. Such as soil is termed "Zymogenic-synthetic soil".
