Successful
Organic Gardening
These three basic rules of organic growing are more common sense than
anything else.
l. No pesticides, fungicides, herbicides or chemical fertilizers
in order to avoid the poisons and salt-based soluble fertilizers that
are so destructive to life, and that inevitably pollute our bodies,
our soil, and water
2. Rotate crops in order to encourage beneficial insects and
reduce pressures from harmful insects and plant diseases.
3. Have a soil building plan in place and working in order for
beneficial micro-organisms to break down the complex materials in the
soil and provide nutrients in a useful form for plants.
While skimming the May/June issue of Organic Gardening Magazine, I noted
the feature article, The Worlds Most Fragrant Flowers,
which goes on to describe more than 150 superscented plants. I think
to myself - what a knockout topic to write about in my next column.
But alas, I remember that Ive already assigned myself the agreeable
task of writing more about organic gardening. In past columns I have
alluded to organic growing practices and have yet to give you the complete
lowdown.
Lets set the stage with a little history of the organic movement.
Until World War II, almost all growers used organic growing techniques
and often used botanical pesticides derived from plants. Pyrethrum and
rotenone are two well-known and widely used botanical dusts. Both are
contact poisons and, as such, are relatively toxic to a wide range of
organisms, including humans. They are, however, short-lived in the environment,
and not known for the kinds of long-term health and pollution problems
associated with synthetics. Sprays made from pepper or garlic juice
have also been used since time immemorial as pest and disease controls,
respectively. Garlic juice depends on its sulfur content for effectiveness,
as sulfur is toxic to all kinds of bacteria and fungi.
During World War II, the first generation of synthetic pesticides, developed
primarily as a result of Allied chemical warfare research, were the
organochlorines, or chlorinated hydrocarbons. The most famous of these
is DDT; but others, some even more toxic, include Chlordane, Aldrin,
Endrin, and Deildrin. These are all nerve poisons. In addition to their
effectiveness at killing not only inspect pests but other wildlife,
they are responsible for numerous human deaths and illnesses. They persist
both in the environment and in the tissues of plants and animals (including
humans), so that exposure to these extremely toxic chemicals is cumulative
over time. Though some of these synthetics are now banned from use in
the United States (most notably DDT), they continue to be sold to third
world countries where they are not banned and are used in growing food
crops, which, thanks to the terms of NAFTA and GATT, are shipped right
back to the United States for consumption. This practice is known as
the circle of poison.
Just about this time, J. I. Rodale, founder of Organic Gardening magazine,
shows up to save the day. Since 1949, the Rodale Institute, located
in the Pennsylvania Dutch countryside, has led the way for organic farmers
and gardeners. The Rodale Institute, whose motto is Healthy Soil = Healthy
Food = Healthy People, is an experimental organic farm, which has produced
much of the data and techniques that transformed organic farming from
a fringe concept into a practical alternative to chemically based agriculture.
Much of the creditability at the Rodale Institute stems from the Farming
Systems Trial, an experiment that has been running at the farm since
1981. The trial directly compares organic farming practices with chemical
methods and stands as the Institutes most significant scientific
achievement. There are 12 acres planted in soybeans, corn, and wheat
that look rather unremarkable. The difference, however, lies in the
soil. One-third of the crops receive conventional chemical fertilizers
and pesticides; another third receives a combination of cover crops
and manure for fertility; and the remainder receives cover crops only.
In their simulation of different types of farms, raising the most commonly
grown grain crops in America, the organic plots have shown comparable
yields to the chemical plots, especially over time as the soil builds
up with organic matter. Rather than going at an impetuous and heedless
pace, regenerative farming/gardening follows the deliberate pace of
nature. This is good.
Next month well explore the various organic ways of preventing
pests from attacking your garden without using chemicals. Stay tuned
for tips on the use of beneficial insects.
In the meantime, you may just have to pick up a copy of Organic Gardening
magazine to get the scoop on those 150 fragrant flowers.
See you in the garden!
