Soil, leaf and tissue testing (Analytical Services)

Analytical Services

BioAg is committed to helping primary producers to achieve profitable and sustainable production. All BioAg nutritional programs are based on the use of advanced analytical services to determine the functional availability of nutrients, soil pH, soil electrical conductivity, soil compaction, plant sugar content and plant energy content. Based on this analysis, your BioAg agronomist will develop a custom-made program which delivers the right amount of plant-available nutrients and biological metabolites to:

Correct observed mineral deficiencies;
Increase microbial mass and diversity in the soil; and,
Deliver an efficient and balanced source of nutrients to plants and livestock.
BioAg nutritional programs can be developed for a wide range of dryland and irrigated agricultural and horticultural enterprises.

Interpretation and Program Preparation

We provide each of our clients with a report for each paddock tested comparing the test results with desirable levels for each of the attributes tested. These reports form the basis for discussion with the farmer, and the prescription of an appropriate BioAg nutritional program for that particular soil and crop.

The programs are backed up by years of experience and significant numbers of independent trials on the application of our products to ensure greatest efficacy.

Soil, leaf and Tissue, Testing and Analysis

Soil Testing

BioAg clients’ soil samples are tested at Southern Cross University’s Environmental Analysis Laboratory according to protocols agreed with us. These are described in the attached paper The Importance of Soil Testing.

Measurement and interpretation of the following parameters enables the most appropriate programs to be developed.

How tightly an element is bound in the soil
Where, when and how much of a soluble fertiliser application is likely to be bound
How much of an element may already be in reserve to be made available to the plant
Changes in the availability of elements over time
The potential risk of “lock up” with “antagonistic” elements

Leaf Tissue Testing

Our clients’ leaf samples are tested by the CSBP Soil & Plant Analysis Laboratory in Western Australia (see http://www.csbp.com.au/Home-Fertilisers/Nutrition-Services/Soil-Plant-Testing.aspx).

We test leaf tissue for the following reasons:

To identify or diagnose a nutrient deficiency
To monitor and manage the nutritional value and quality of the grass/crop grown (essentially using it as a tool to identify a “hidden hunger”).
To provide justification for some recommendations, offering a rational reason for the application or non-application of something, such as “more nitrogen”.
As a cross reference tool with soil test data to provide more confidence in data interpretation.
As a verification tool to check if a foliar application or system is working.

Petiole Testing

Our clients’ petiole samples are tested by the CSBP Soil & Plant Analysis Laboratory in Western Australia (see http://www.csbp.com.au/Home-Fertilisers/Nutrition-Services/Soil-Plant-Testing.aspx).

Petiole analysis is a useful tool to assess the nutrient content of vines at a selected time in the growth of the plant. It can be used to determine appropriate fertiliser applications in the general maintenance of a vineyard (nutrient monitoring) or to assist in determining the cause of specific problems (diagnostic testing).

Nutrient monitoring can be used to assess the adequacy of current fertiliser practice. Nutrient concentrations in a vine vary from year to year as the uptake of nutrients is affected by the seasonal conditions. Monitoring the nutrient concentrations of vineyards over a number of years enables growers to observe trends in the nutrient concentrations and make appropriate adjustments to their fertiliser programs to ensure nutrient requirements are met.

Diagnostic testing can be undertaken to assist in the diagnosis of lesser performing vines or to confirm a diagnosis made on the basis of visible deficiency or toxicity symptoms in vines.

Soil, Leaf and Tissue Sampling Procedures

Careful sampling is required to ensure accurate analysis which affects the quality of the programs we provide our clients. We have developed sampling procedures which may be carried out by the farmer, or the BioAg agronomist. These may be accessed by clicking on the following titles:

Soil Sampling

Leaf Sampling

Petiole Sampling

Petiole sampling is undertaken by our qualified viticulturists and horticulturalists according to a method established by the Cooperative Research Centre for Viticulture, and tested at CSBP Soil and Plant Analysis Laboratory.
