Re: Rainy days;
- Fukuoka-sensei makes swales or there equivalent in function, by burying large timber -
logs- in trenches that are dug by hand, and ? across contour. Timber rots to a highly
porous and absorbant, water storage or drainage space under the soil surface. Fukuoka-
sensei has no need of soil destroying heavy machinery for making swales. This would be
the way to adapt the approach taken in the youtube movie for the long ?swale?, it would
require more patience than the instant gratification that the mpvie appeals to, but
sustainable approachs always require patience (Yes, Bob). Thanks for that movie. It is
worth watching Deiter.
And also Linda for your solutions.
