use of pulling roots from the ground (destroying billions of microbes,
fungi and the natural soil fertility in the process) then
heap-composting the roots (in the process of which a lot is lost into
the atmosphere) and then returning the meager remains back to the same
soil? That is crazy!
>Do you live up to that yourself?Yes! Except for a few weeds with deep taproots that have the tendency
to keep on producing seeds, all roots (weeds, food crops, trees,
bushes, everything) stay in the garden soil. From the fields I don't
remove any roots at all. When weeds start to crowd out food crops, I
either cut them above the ground and spread the remains on the soil
surface or I trample them down and put on some mulch.

soil is almost always a sign of low organic content. A soil with high
organic content can store huge amounts of water without getting
water-logged. You need to return OM to the soil, a lot of it, not
just a few microbes.
Anders, I don't blame you if you think that Natural Farming is a fake
or just an idea without reality. So many people have talked about it
and so few have ever really tried. Fukuoka deserves our greatest
respect for having demonstrated that it is possible and for having
made his methods known outside Japan. Unfortunately, his methods are
not very practical and his singular way of spreading the message has
led to some serious misinterpretations. But Natural Farming is not
Fukuoka. There are many others, notably in Japan, who follow their
own way of Natural Farming. Some are content to grow their own food,
others run what could be termed commercial market gardening
operations, most even grow the staple rice.

to BD. I have said time and again to forget all about Fukuoka (that
is also what he himself told us) and to find the way that works best
in your place. But you need to understand that NF does work, not any
fancy idea of it, but the reality of NF which is (stripped it to its
very basics) _to grow food without fertilizers_. And in fertilizers
here I include: synthetic fertilizers, manure, compost and even
external inputs such as mulch, rock dust or a million other soil
After the harvest, Kawaguchi will return the straw to the field, he
will also return the rice hulls and the rice bran (kome nuka: the
stuff that remains after the whole grains are processed into white
rice) from the plants that have grown on that field _only_. Nothing
more! And yet he continues to get two harvests a year (rice and
wheat) year after year. There was a thread on a Japanese ML only
yesterday discussing the yields of Natural Farmers. According to this
discussion Natural Farmers in Japan have a yield of 6 to 8.2 Hyou (360
to 500 kg) of rice for one Tan (0.245 acre). I have no idea about
typical rice yields, but those figures seem far from bad, considering
that no external inputs and no plowing are required.
The last time I received a load of manure from a neighboring cattle
farmer is already 6 years ago. Since then I had no external inputs.
I still use mulching materials from our own meadows and hillsides to
enrich the garden soil, but I think in a few years time I will be able
to stop that too. I used to make enormous amounts of compost;
windrows of almost 50 meters every year. Now I use most of it for
mulching. It is much more effective that way.
Seeing is believing: the soil will continue to produce food year after
year without compost and without manure only through its
self-fertility. It has been difficult at times to get there but it is
worth it. Just put a plant or a seed into the soil and it will grow,
no more composting and certainly no bother with beastly big animals.
