Plant Tissue Testing
Plant tissue sampling has some crucial elements such as timing, growth stage, plant part and the number of leaves required for testing and sampling varies between crop types.
Plant tissue analysis is normally used for the following reason:
To determine the reason for poor growth, or to check on accumulation of mineral elements toxic to plants.
To assess the suitability of current management practices over time, adjusting existing fertiliser programs if necessary to ensure optimum yields are achieved.
Collecting a Plant Tissue Sample

Fill out the appropriate Submission Form making sure to supply the correct customer account number. Fill out ONE Form for a maximum of three samples taken from the same paddock or with the same histories. These samples can be all topsoils, deep soil nitrogen tests or subsoils, or a combination of these test options.
Ensure a test code is clearly indicated using the current Nutrient Advantage Price List.
Double check that the barcode numbers on the completed Submission Form match the barcode numbers on the sample bags (remember to keep one for your records). Remember that you must supply accurate information so that correct interpretation and recommendation of test results can be made.
Place all forms in the clear press seal plastic pocket provided. Place the submission form and soil samples into a Freight satchel and seal and deliver to:
