Whoa there, Bobber "the soil can lock up foods for plants unless man helps it along"?
Soils in a natural state do not lock up anything that the local ecosystem wants or needs. Soils out of balance can lock things up, but that is the hand of man imbalancing them in any case; natural progression of soils is generally a smooth slope from bacterial soils to fungal soils. In some areas (deserts, plains) there is not enough moisture and the progression is arrested, but it is not lack of fertility. In any area left to it's own devices, nature provides...
You can get bacterial lock in a soil beaten to death by tillers, because the fungal component is completely destroyed, as is the tilth, making for compacted, less aerobic soils, which favor bacterial growth, particularly of the facultative anerobic variety. But a good soil left be becomes a better soil...
Leaving things be is a BIG part of F-san's message. Man's "quicker" mind is far too ignorant of the natural system with it's long slow cycles, and leaps to far too many conclusions based on what he would LIKE to be true (some of the recent posts are fine examples of this thinking). THIS is the recurrent theme of this book...
The main theme of this chapter is cow vs. machine, nature vs. science, not tea, or philosophy.
The idea of relative phemonena is a structure given to experience by the human intellect.
Indeed, this appears to me to be what Gershon and Bobber have done in their interpretation of the chapter, they are discriminating in their own minds about what F-san says, and drawing conclusions based on their perceptions. I hear a much different story, one that will not allow me chemical fertilizers or tillers, and leaves me with a garden far more like Sensei's own. There is certainly a relativity there, and again one born simply of paradigm and perception. I leave it to your individual perceptions to draw what conclusions you may...
...the role of the scientist in society is analagous to the role of discrimination in your own minds.
Nature does not care what we think, or even for our science. It will do as it always does, whether we interfere or not. When we are of a mind to hear what Nature has to say, to follow her dictates instead of imposing our "quick" thinking on her, we will find a truly sustainable way to farm and garden. Until such time we will continue to mine our soil as a depleting resource...
