JADAM Organic Farming 
Old friends of JADAM will have a special
memory of the Jiri Mountains. JADAM
had tried and experimented with many
methods based on the one developed
by Mr. Hankyu Cho, who laid the foun-
dation of JADAM organic farming sys-
tem. Once, we even cooked 10 huge
pots of rice to promote the use of our in-
digenous microorganisms. JADAM’s
current method is a significant develop-
ment from this. It has been simplified to
the extreme while still improving effec-
tiveness..

2. JADAM indigenous microorganism soluion (JMS)
Under the leaf mold in the mountains live millions of different indige-
nous microbes that have adapted to the local environment. Use them as
starter. Use potatoes or grains as medium (feed). Apply continuously
throughout growth but intensively before transplanting for annuals and be-
fore lowering/sprouting for perennials. It reduces soil salinity, helps root
settlement, prevents nematodes and wilting. Developed by Youngsang Cho. 
Pour 500 L (132 gal) of water in a container. Dissolve 0.5 kg (1.1 lb) of sea
salt into the water. Put 1 kg (2.2 lb) of boiled potatoes, 0.5 kg (1.1 lb) of leaf
mold and some rocks in a ine net bag. Hang the bag over the container so
that the bag is underwater. Knead well so that the contents melt into the water. 
To culture crop-customized microbes, blend 1 kg (2.2 lb) of crop residues
(fruits, leaves, branches), put it in a ine bag and hang it over the container. 
Close the lid and leave under the sun for culturing. Place it in the same en-
vironmental condition as the crops. Leave it at ambient temperature. It takes
1-3 days till completion. It is faster, and there are more foam in summer. If
water temperature drops below 18
℃ 
(64.4
℉
), use an electric heater to keep
at 20
℃
(68
℉
) and wrap the container with insulation. (If you use cold un-
derground water, take out the water and leave for a day for it to warm before
use.)
When foam is at its most vigorous and the edges of the disc is clear, it is
time for use. If you are just one day late, the edges will crumble and the mi-
crobes will die so is useless as JMS (in this case, use as JLF). Dilute 10 times
with water and use up completely. 500 L (132 gal) of JMS can be applied to
0.1 to 3.3 ha (0.25-8.2 ac).
When applying JMS through a hose or on the leaves, ilter with a ine net.
Run clean water through hose after running JMS. For foliar application, dilute
over 20 times and mix with JADAM wetting agent (3 L for 500 L, or 0.8 gal
for 132 gal).

JADAM Organic Farming 
Microbes are extremely small forms of life only seen under a microscope.
ey include protozoa, algae, fungus, bacterium and virus. Approximately,
2 to 10 billion microbes live in 1 gram of leaf mold. Fungus and bacterium
are decomposers that recycle nutrients. Protozoa are predators that control
the microorganism population. Just as the food chain exists in our visible
world, so too does it in this tiny universe. A variety of decomposers and
predators form a complicated relationship. As they feed, excrete, breed, die
and decompose, soil environment changes; it recovers vitality and fertility,
and becomes optimum growing ground for plants. Most of the nutrients re-
quired by crops are produced by microbial activities. Microbial conditions
and farming are directly linked. 
Some algae and bacteria can make food by themselves through photo-
synthesis or chemical reactions. Autotrophic microbes synthesize their food
themselves. Heterotrophic microbes are those that rely on feeding for food.
Aerobic microbes like oxygen while anaerobic ones dislike exposure to air.
Microbes that have adapted to both environments are called conditional
aerobic (or anaerobic) microbes. In nature, aerobic and anaerobic processes
are not strictly separated. Many microorganisms change from one system to
another according to their situation. Acidophilic, neutrophilic and alka-
liphilic microbes respectively favor acidic, neutral, and alkaline conditions.
e majority of disease-causing pathogens are classiied as acidophilic, so
most of the time disease breaks out when the body luid of the crop or the
soil is acidiied. Most microbes survive between -10 to 110
℃
(14 to 230
℉
).
Depending on what temperature they like, they are classiied into psy-
chrophile, psychrotrophile, mesophile, thermophile and hyperthermophile.
e lower the temperature the microbe likes, the smaller its body size tends
to be. ere also exist microbes living in extremely low or high tempera-
tures. If you catch a ly and put it in a freezer, it will appear dead. However,
if you take it out to room temperature, it will come alive again. Microbes
are even more like so; they become dormant or active according to the
changing conditions. ey adapted to their environments over billions of
years amid the challenges of nature: high or low temperatures, too much or
too little moisture, acidic or alkali soil, aerobic or anaerobic environments

and so forth. Some microbes have been reported to wake up from thou-
sands of years of dormancy to be fully active again. 
Some complain that crop yield decreases after switching to organic
farming from conventional farming. is is because soil microbial activity
has not yet been fully normalized to the original natural level. Chemical
pesticide, fertilizer and herbicide have decreased the biodiversity, popula-
tion and vigor of the microbial ecology. Even if you add organic matter to
this kind of soil, they are not broken down rapidly due to the weakness of
the microorganism activity. is in turn causes nutrient deiciency for
crops, thus the low yields in the early stages of transition to organic farm-
ing. If you make efforts to restore the soil microbial abundance in advance,
cutting off chemical fertilizer and replacing them with organic matter does
not signiicantly reduce yield; in many cases, yield actually increases. 
Modern science knows less than one percent of the total number of mi-
croorganisms in existence. We know this because only one percent of mi-
“Flower” of microorganisms blooming on cooked rice. Modern science knows almost nothing
of this world. JADAM does not select a few “good” microorganisms and use them. JADAM
embraces the whole microbial diversity by using leaf mold; this way, you can use microor-
ganisms that have adapted to the local environment.

croorganisms can be cultivated with the methods developed by science. If
we cannot cultivate them, we cannot study them. Another amazing fact is
that microorganisms are constantly evolving – probably at a rate faster than
the development of science. is means that we might never know more
than that one percent that we think we know now. Modern farming recom-
mends the input of “good” microorganisms and teaches us to suppress the
“bad” ones. Selective usage of microbes is regarded as scientiic farming.
However, it is nonsense to divide “good” and “bad” microorganisms. We
simply do not know well enough to tell which is good and which is bad.
Remember, we know less than one percent. ere have been quite a lot of
researches done on some well-known pathogens, but we only have some
very basic information about most other microbes. Moreover, we have no
knowledge on how the species relate to other species to form this compli-
cated micro-ecosystem. 
JADAM believes this dualistic thought of dividing good and bad is actu-
ally unscientiic, furthermore, it is invariably linked to a commercial moti-
vation. What is a microorganism? JADAM simply sees it as a “worker.” We
want to boost the workforce in our ield where the crops are. en the best
way to do that is to bring in workers from an environment closest to that of
our ield. Where are they? ey are in the leaf molds in nearby forests, hills
and mountains. It makes no sense to look for microorganisms imported
from other places or countries. How can you bring in a foreigner and ex-
pect him/her to suddenly speak the local tongue, mix with local population
and become a good worker? 
Use the leaf mold as the starter for microorganism culture. JADAM does
not separate the “good” ones from the leaf mold and use them selectively.
Narrowing down microorganisms means narrowing down the pool of nu-
trients available for plants. Selective use of microbes will result in an imbal-
ance in nutrients. Stop narrowing and start expanding, embracing.
Restoring diversity and population of soil microorganism will give you re-
markable results. JADAM believes that this is the best approach we can take
as of yet, taking into consideration the very real limits of modern science.
e cost is much less than commercial microbes but is just as effective. It can
