Korean Natural Farming is established by Cho Han Kyu after he studied natural farming in Japan. He mixed the Korean cuisine with farming practices to come up with cheap solutions for farmers.
Later he and his son established JADAM (not an abbreviation) which means "People that resemble nature" to help farmers to produce high yield without using corporate fertilizers.
Han Kyu talks about nutritive cycle of a plant which when observed we can see that at different stages, it needs different kind of fertilizer
These cycles are:
Vegetative Growth Stage (from seed to first flowers or 3rd set of leaves)
Cross Over Period (first flower to visible fruit)
Reproductive Stage (fruit ripening stage)
Dormancy period (added by me)
The preparations in Korean Natural Farming are:
IMO - Indigenous Micro Organisms
Collecting healthy starter culture from a healthy area and inoculating your land with it. Rice or potato used.
FPJ - Fermented Plant Juice
A chosen plant is mixed with half its weight of sugar. Dry sugar does an osmosis affect rapturing the cell walls and releasing the nutrients.
FFJ - Fermented Fruit Juice
Fruits of a chosen plant mixed with same weight of dry sugar. Resulting liquid used on plants
OHN - Oriental Herbal Nutrients
Garlic, Angelica, ginger or turmeric, licorice and cinnamon tinctured using vodka. This is a strong antifungal and used as a medicine on plants
FAA - Fish Amino Acids
Wild caught fish pieces mixed with equal amount of dry sugar. Resulting nitrogen based fertilizer used on plants
LAB - Lactic Acid Bacteria
Rice wash cultured first to collect bacteria and inoculated with milk. LAB used on compost and gardens
WS-K or WP - Water soluble potassium
Potassium rich plants like tobacco, spinach, broccoli, cucumber, zucchini etc. dunked in water. Liquid then used on plants.
WS-PA or WPA - Water soluble Phosphoric Acid
Charred parsley or sesame stems dunked in water to extract phosphoric acid
WS-CA or WCA - Water Soluble Calcium
Slightly cooked egg shells mixed with vinegar which dissolves the calcium. Resulting liquid diluted and used on plants
WS-CaPo or WCAP - Water soluble calcium phosphate
200 grams of charred bones mixed with 2L of vinegar. It dissolves calcium phosphate into the liquid.
BMW - Bacterial Mineral Water
Granite, basalt, elvan, marble stones continuesly washed with IMO4 inoculated water. This process dissolves the minerals from rocks.
BRV or ACV - Brown rice or Applecider vinegar
used diluted in other preperations
Yeast - Collected yeast used in preperations
SW - Sea water
Surface sea water collected and diluted to get the benefit of sea water micro-organisms
JADAM later on established by Cho Han Kyu's son Youngsang Cho and eliminated sugar from its recipes. I see JADAM as a complimentary to KNF as the recipes are different but principles are pretty much same.
Thank you Gurkan for a concise set of definitions and the history of the two methods.
When I really got to looking into the philosophy of KNF I realized that it was (like most methods) born of a conglomeration of ancient and current methodologies.
Cho san and I would disagree on a few points though since his method seems to want you to make additions yearly which means far more work than the earth mother would require.
It should also be noted that there are parts of the method that don't perform as well as straight forward permaculture techniques and the U of Hawaii did a large scale study and made some enlightening comparisons; KNF to permaculture to Commercial standard methods.
The commercial standard was always at the bottom (as I expected it to be) but the others seem to swap places depending on what is grown and which preparation was being used.
For me KNF is worth adding to the mix but I would not use any singular method and depend on it to do everything I desire for my soil and plants.
This is a picture of an Excel sheet I prepared to show how much and when each Korean Natural Farming preps to use. It is fixed with the help of FB group members but if you see any mistake please let me know.

Could you please give us some detail on the large scale study done by the University of Hawaii?

If you download the PP slides linked on the first post, you will see the Nutritive Cycle Theory. This theory recognises the different stages of a plant requires different fertilisers. You can then use the chart above to make a decision on when to use specific KNF inputs.
