permaculture

Here are some of my own resources, original writing (that needs revising to
account for new information) and collections of articles, links and
archives plus links to the original document and other collected resources:

It can be found online in my Gardening Hand Tool Sourcelist

It includes information on remineralization. Additional information on
composting, nitrogen sources, beneficial microorganisms, mineral and
plant-animal-based soil amendments will be added later.

Raised Bed Gardening Using the French Biointensive Double Digging Method

The essence of it is that you invest a lot of effort and materials up
front, inverting the soil, fragmenting the crumb structure, with
associated temporary disruption of soil life and soil structure,
oxidation of organic matter and release of co2 through exposure of humus
to air in order to improve soil tilth, fertility, drainage, water holding
capacity,
cation exchange capacity, organic matter content and overall soil quality
provifing an
improved and healthy medium for hosting beneficial microorganisms and other
creatures
that make garden soil their home. You remove much of the soil in the bed,
add organic
matter and mineral based soil amendments to it, homogenize these materials
then
return the amended, enriched soil mix to the bed. This is done in
increments of one (typical short (42" to 48" English D-handled *see below)
digging
spade blade width wide and one spade blade length deep for the width of
the bed (38-50" wide depending on the gardener's height).

You want highly mineralized soil, high in tilth and fertility, producing
vegetables and fruits with exceptional flavor.
Add rock dust from quarries to your garden soil for trace minerals, microbe
food and tilth, permanently eliminating soil
compaction. This is called siltation pond fines. It is so fine that if you
put some in a glass of water it turns cloudy
and stays that way for quite a while before settling into a layer of sludge
on the bottom; so fine it would take a microscope
to see the individual particles. This is great material to feed plants and
soil microorganisms and invertebrates in your garden.
I think we are talking 200 mesh or finer; some fines are a little coarse by
comparison to my basalt/tuff fines and some are an
aggregate with the largest component almost microscopic, like the talcum
powder in pyrophylite fines (dredged from the quarry's siltation ponds).
To prevent compaction, permanently, fines act mechanically to interfere
with clay and silt particles that when compressed when wet become highly
compacted when dried out - a serious problem for gardeners needing
productive high-tilth soil.
I have used  this material to enrich soil for the benefit of plants,
microorganisms and invertebrates and to permanently
prevent any compaction of my soil that would significantly reduce the
productivity of the gardens. The materials include
"siltation pond fines" from the following types of rock: granite, volcanic
tuff (maybe basalt, very hard rock, 2nd hardest in NC)
and pyrophyllite screenings. I am glad to hear that granite, high in silica
is a sink for lime making my soil acidic,
good for most crops, pH 6.1 to 6.6 or so. Tillage is expensive, disruptive
of soil life and inconvenient when it needs to be done
and the soil is too wet; i.e. weeds can get out of control and go to seed
when tillage can't be done, like in Spring, to remove them and
create a fine, weed free seedbed for new plantings. Fines are mixed with
existing soil on site, sometimes in a 30 or 40 to 50 ratio.
The clay or silt particles become permanently separated from each other and
cannot be seriously compacted again.
This effect is also achieved with the addition of compost or manures to the
soil. The fines feed the microorganisms
that help break down the fines and make trace minerals available to plants;
these microbes also break down any raw or composted organic matter
added to soil to become humus, feed released nutrients to crops and improve
the soil crumb structure providing added tilth to your garden soil.
The extra trace minerals in garden soil makes crops taste much better. The
famous tomatoes grown in volcanic soils in places in Italy taste so
good for this same reason. That's how fines relieve compaction and add to
soil health and vitality, crop health and disease and predator
resistance and crop flavor, appearance and keeping qualities. More about
fines dissolved in water. In places in the high country areas in
Eastern countries people drink cold river water that is cloudy and high in
mineral content; they live long lives.

I would remove the top 8" or more of your raised bed-to-be. Then, "in situ"
(without turning or inverting the soil layers) tilth
or dig up and pulverize an additional, lower 8-12" of subsoil; add
amendments of all sorts to the 8" of soil you removed then put
it back in place on top of the subsoil layers you just tilthed - then you
will have a "raised bed", the new garden bed surface will
now extend 4-8" above existing grade.

This will address any concern about your garden drying out during drought
times if you use raised beds. The benefits outweight the
disadvantages aand with the following technique you will have no problems
whatsoever.

Avoid having paths between the beds that are level with existing grade but
ditches or furrows between the beds. These provide
much needed drainage and you can fill these ditches with mulch, weeds, hay,
etc all the way up to the tops of your raised beds.

You want to to accomplish the objective of increasing depth of tilth and
fertility in the soil in your beds. Mulching the top layer is
mandatory. Mulch will decompose leaving the seedbed fine and loose while
leaching humus and compost tea into lower layers of garden soil
including sub soil areas to depths of several feet (partly because you have
already tilled this zone). You want a permanent, notill,
biointensive raised bed that gets better each year through the action of
compost tea, humus and nutrients that leach from the top layers
into the lower layers; that's a real "trickle-down bioeco-economy" with big
pay back in quality produce for the table and for market.
This is real Pay Dirt as J.I. Rodale described it.

After this process is completed you need never again turn your soil,
except to a depth no greater than is necessary to control newly emerging
weeds, break crust and create a fine, loose seedbed. You now have
biointensive no-till, permanent raised beds.

This technology has been around for centuries and it works.
There is a very big net gain for soil, its inhabitants and the environment.

"Emilia Hazelip (1938 - February 1, 2003) was an organic Permaculture
gardener who was born in Spain and began gardening seriously in the late
'60s. A former Merry Prankster and pioneer of the concept of synergistic
gardening, her farming methods were inspired by the work of Masanobu
Fukuoka. Where Fukuoka focused most of his attention on orchards and the
rice/barley crop rotation, Emilia Hazelip focused on creating and
maintaining market gardens of vegetables and herbs. Emilia Hazelip, who
introduced the concept of permaculture to France over a decade ago,
drew on many sources as she continued to develop gardens.
The work of Permaculturist Marc Bonfils with self-fertile
cereal production and the microbiological research of Alan Smith and
Elaine Ingham are frequently mentioned.

Double  digging is as essential and indispensible to gardening anywhere
in the world, where the climate does not mandate other methods, as grain
is to bread.
