Very good presentation by Kristine Nichols. I think that her explanations help to demonstrate the value of Fukuoka's methods of no till, no fertilizer, no pesticide, and no herbicide.
Do not till "with iron". The natural life on the farm keeps the soil tilled and aerated. Weeds plow, moles plow, earthworms plow.
Do not give fertilizer. If plants are spoiled with too much fertilizer, they do not feed the mycorrhizal fungi, ruining the symbiotic relationship and thus the resiliance of the plant.
