In agriculture, chitosan is used primarily to activate plant defenses and to stimulate growth, not to fertilize. When applied to plants or soil, it triggers natural immune responses, stimulating the production of defense enzymes, phytoalexins, and other protective compounds. This can increase resistance to fungal, bacterial, and viral diseases. Because it works by signaling and strengthening plant physiology rather than killing pathogens directly, chitosan fits well within re

POTASSIUM DEFICIENCY occurs when soil is lacking potassium. Even when sufficient potassium is present, if the soil contains high levels of lime and magnesium, the plant still suffers from potassium deficiency because these elements suppress potassium absorption. Potassium deficiency can also easily occur in sandy soil, which has less humus, because potassium is readily leached from sandy soil, as with nitrogen.   Using a soil foundation with Indigenous Micro-Organisms (IMO)

How are minerals used in KNF if soil amendments are not a regular part of crop establishment and management? In a word, the answer is Seawater. This is not the only source of mineral elements in KNF, but it is the most important. There was a pasture in Hawaii that was doing poorly, with a lot of weeds, but very little edible grass and forage. A livestock expert and KNF practitioner had the rancher apply seawater to the pasture. Nothing else was done, but everything changed. G

While most KNF teachers will have you learn all the inputs for Korean Natural Farming first, that is not my advice. It’s not helpful to make
