A side note to this: An Australian
friend who spent most of his life there, is a Master Naturalist and Master
Gardener, as well as a member of our Native Plant Society of Texas, said that,
in his view, Australia has reached the point of "Environmental Consciousness"
sooner than the US, simply because their margin of error (soil, water) was
thinner. Rings true!

The
objective of the Petrik system is to produce nutritionally complete
food
from strong healthy plants that require minimum chemical assistance
to
produce optimum yield and quality. Petrik are world leaders in
soil
microbiology. Through understanding and working with nature the
simplest
description of our aim is, "the creation of stable humus".
Conventional
growers lament the loss of productivity from previously virgin
soils over
time, increasing chemical inputs in an attempt to prop up
falling yields.
Stable humus is degraded by inappropriate fertiliser and
chemical use.
As this happens the soil loses structure restricting the
operation of the
native biology. The Petrik system focuses on the plant
microbe
relationship. The objective is to provide the optimum physical and
chemical
environment to allow the plant to maximise the benefits from soil
biology.
Once the soil chemistry is corrected application of field
toughened biology
starts the creation of stable humus paving the way for
the soils indigenous
microbes to again operate at full
efficiency.
Plants exude between 10 and 25 % of the photosythates they
produce into the
rhizosphere to support beneficial microbes, conventional
modern agriculture
ignores this resource.
You already have microbes
in your soil, they are however in many cases
restricted from operating by
chemistry, structure and organic matter
limitations. If you are going to
add microbes, you have to add microbes
that can handle the conditions that
are currently limiting your indigenous
microbes. Petrik Digester initiates
the humus creation process. In soil
which is chemically balanced, this
humus glues the soil particles together
giving permanent structure. This
structure gives the soil porosity allowing
air and water movement and the
proliferation of indigenous microbes.

Petrik History
Vaclav Petrik, (senior)
began producing commercial preparations of soil
microbes 1947 in
Czechoslovakia. Petrik developed their first stable
products that could be
bottled and stored in 1961. The comprehensive Petrik
Soil Test was
developed in order to ascertain amendments required to
provide optimum soil
chemical conditions for the performance of the
biology. While developing
the Soil Test Vaclav Petrik Senior corresponded
with Dr William Albrecht
and the principal of cation balance is integral to
the system. The soil
amendment system incorporates anion management and
demonstrates the unique
understanding of anions affect on
cation
availability.
