I wondered if Fukuoka ever mentioned Mokichi Okada and his school which is usually called 'Nature Farming' or Kyusei?
I can see the big difference but I wondered if there had been any interaction between the two of them?
I know it is way 'off topic' and in the opposite direction for Fukuoka's style but Kyusei and the use of "Effective Microrganisms" or EM Technology for conventional organic farming is far more common even in Ehime.
Governor of Ehime Prefecture declared EM as a prefectural policy. He allocated supplementary budget and personnel to act on his policy. This Governor persuaded Governor of Hiroshima Prefecture to begin his prefectural application of EM. Furthermore, through the efforts of Ehime Governor, the prefectural Governors of Hyogo, Nara, and Wakayama have shown understanding of this movement. Now the future of Seto Inland Sea is secured.
As an introduction, I think the mix is basically some yoghurt and natto spores.
