TGS is supported by the unique Petrik tools system of soil, tissue
and water testing.
Soil Analysis Report
This system enables diagnosis of chemical limitations in the soil
prior to application of biology. More than 60 years experience in
the field has lead to the Petrik test which presents a simple easy
to read graphical depiction of your levels against optimum levels
of each essential element for your soil.
The test includes kilograms per hectare recommendations for each
element to reach optimum soil conditions. The Petrik system also
evaluates and rates ratios between elements. This system support
enables growers to provide the optimum chemical conditions for the
Petrik biology to operate in. By evaluating and improving the chemical,
physical and biological properties of the soil the Petrik system
is able to deliver complete nutrition.
K
is at 64 % of desired level and the field need in this case
to correct to 15.7cm is 164 kg/ha of potassium. |
Petrik Tissue Report
The Petrik tissue test shows tested levels of essential elements
in the crop against critical and target levels for the specific
crop stage. These elements are then ranked with respect to limitations
to optimum production to highlight elements for foliar correction.
Recommendations for application of these elements in grams per hectare
are included in the report. While foliar application can be very
useful in amending temporary deficiencies, our primary objective
is to create optimum soil conditions for the support of the soil
life the crop.
In
this example potassium is the 3rd element most limiting to
optimum production. This Petrik interpretation specifies 1950
g/ha of K be applied in conjunction with Petrik Impulse 200
for immediate temporary rectification of deficiency. Long
term amendment will always require addressing soil availability
and uptake issues.
