Turf Inspections

ASTC conducts independent turf farm inspections for quality control (breeder) purposes, turfgrass certification, sports field and commercial installations for clients. This includes routine inspections, turf certification, turf suitability and pre-harvest inspections.

During inspections ASTC looks to assess: 

ASTC can also collect sampling for analytical testing, including DNA, soil nutritional, soil physical testing, leaf nutritional, water nutritional testing and pest and disease identification etc.

Turf Certification

An example of a certificate is provided below. A turf certification certificate can be provided following an independent farm inspection. Documentation of this nature is often requested for Quality Assurance purposes.

Turfgrass Rating

The Turfgrass Certification “Turf Rating” (0.6 to 5 stars) is based on the following information and criteria:

Supplementary comments are also provided on notable observations made during any inspection. Recommendations may also be listed, if applicable, for the turfgrass to be deemed suitable to meet specification or be fit-for-purpose.

Contamination in Turfgrass

In recent years numerous discussions have taken place between turf farm owners, breeders, consumers and/or IP Australia (who administrate Australia’s intellectual property (IP) rights system, including Plant Breeder’s Rights (PBR)) regarding turfgrass contamination. ASTC Director Matt Roche asked the [now former] Chief of Plant Breeder’s Rights Mr Doug Waterhouse the following question regarding quality control and contamination within PBR protected turf varieties.

Question. “If contamination is found within a PBR turf variety growing on farm, is this considered unacceptable and can the turf farm or breeder be in breach of the PBR Act [Plant Breeder’s Rights Act 1994]?”

Answer. “There are many elements to this question, not all of which are PBR; for example, the Competition and Consumer Act 2010 (formerly known as the Trade Practices Act 1974) adequately deals with mendacious variety declarations. Thus if a grantee sells turf as one variety when it is actually another, recourse is through normal competition law.  Accordingly both seller and buyer should establish the purity of the material on offer.

In addition, PBR accepts that varieties have some “contamination” usually by way of “off types”. This is the “uniformity” standard of which you are aware. There is also the “stability” standard, though for asexually reproduced varieties, this is of lesser importance.

In relation to uniformity, there comes a time when the material is so un-uniform that it no longer complies with the variety’s description – and therefore is arguably not the variety anymore.  Obviously this does not apply to (deliberate) admixtures which fall within competition law as outlined above.  Grantees are responsible to ensure that their varieties remain true to their description when grown in the relevant environment” (D Waterhouse 2013, pers. comm., 12 September).

Of significant note is Mr Waterhouse’s comment in relation to “Accordingly both seller and buyer should establish the purity of the material on offer.” This should be in the form of independent turfgrass inspections and turf certification.
