Jadam organic Farming & Gardening : The Way to Ultra-Low-Cost Agriculture, Make All-Natural Fertilizer, Pesticide and Microorganism Inputs Yourself

You will learn many useful new methods including increasing mi-
crobial diversity and population, boosting soil minerals, tackling soil
compaction, reducing salt level, raising soil fertility and more. is
book also shows you how to make natural pesticides that can replace
chemical ones.
What is amazing is that not only are they cheap and effec-
tive, but they are remarkably simple and easy to make. 
When farmers begin to make their own inputs, farming can inally de-
clare independence from the corporations. Ultra-low-cost farming is possi-
ble only when farmers are the masters of their farming. It is a tragedy for
nations and indeed all of humanity if agricultural technology is monopo-
lized by big businesses. JADAM is not simply about lowering farming costs;
it is the product of my life-long contemplation and relection on the histor-
ical, philosophical ecological aspects of agriculture. It is JADAM’s goal to
bring forth a change in the world with the ultra-low-cost agriculture sys-
tem. Agriculture shall change at individual, national and global levels. Or-
ganic farming will be popularized; both farmers and consumers will be
happy; humans will live in harmony with the nature. 
We have been operating our website www.jadam.kr for 14 years now.
Ultra-low-cost agriculture became quite well-known in many countries. We
are receiving many questions. JADAM organic farming has its root in

Korea; it was founded and developed on Korean soil. is means that for it
to be transplanted to other countries, it would need some adaptations and
adjustments. But I can assure you that JADAM organic farming will be a
powerful tool in other regions, because fundamentally JADAM does not
advocate individual material or inputs; it is methodology, principle and
spirit. Over 20 years passed since JADAM started its activity. Members reg-
istered in our website and those who inished our workshop count nearly
60,000. I am grateful that many people have shown interest. I especially
thank our sponsors who supports us with 10 dollars or more every month;
it has helped us immensely through our periods of hardship. Without sus-
tained help, JADAM would not have stood through the decades. JADAM
would not have been able to produce this original vision of “ultra-low-cost
agriculture.” ank you! 
Many farmers also helped JADAM by providing invaluable knowledge
that they gained from life-long experience and their experiments of
JADAM method. I deeply thank them. is book and the website
www.jadam.kr are testimony to what great a result can be achieved when
farmers come together to share wisdom. 
Collaboration with the Korean Rural Development Administration
(RDA) enabled us to present a detailed numerical analysis of JADAM in-
puts. I thank Dr. Hyeongjin Ji, former Organic Farming Division Director,
and Nanhee An of the RDA. Special thanks also to: Dr. Chunu Nam of
National Institute of Horticultural & Herbal Science who included me in
his research to help organize JADAM system in a scientiic fashion; Jongseo
Bak, president of National Environment-friendly Farmers Association who
helped greatly in promoting ULC; Director Gwanggu Yi and Jaebeom Na
of the Buyeo National Agricultural Products Quality Management Service;
Jiyeon Jo of Gangjin district office; Sangwon Yi of Buan district office;

If it were not for the achievements made by Han-kyu Cho, my father,
JADAM system would not have been born. He has devoted his entire life in
promoting natural farming and built a strong foundation for the ultra-low-
cost agriculture system of JADAM organic farming. I thank Jeongho Gim
of Bongha village who audaciously attempted JADAM organic farming on
a scale of 330 acres and led that to a success. He proved that JADAM sys-
tem can be used on large-scale farms. My appreciation also goes to Dae-
hong Chae, ex-president of Suncheon Agricultural Cooperative; Seung Suk
Lee, Chairwoman of Advisory Committee; Donggeun Choi, president of
the Korean Federation of Sustainable Agriculture Organizations; Dongchun
Choi of Buan. I thank my JADAM family, who have withstood the ordeals
with me: Myeongsuk Gim, Geol Yu, Gyeonghi Yi, Won-gyeong Yi, Sanghi
Yi, Gyeongho Gim, Muncheol Yu, Hyunho Cha, Rei Yoon, Sunyoung
Cho, Sung-eun Cho, Sungwoo Cho, and of course my wife Sunhwa Ju,
who gave me so much advice in writing this book.
