Variation in fertilizer application rates across a paddock is inefficient and can significantly reduce plant productivity. Poor understanding of spread patterns and over-application of nutrients can also result in fertilizer loss and off-site water quality problems.
Accu-Spread is a testing and accreditation program that ensures a spreading machine can apply fertilizer evenly across the paddock – maximising productivity and minimising environmental damage. It allows operators to determine how wide and how evenly their machinery is spreading. If necessary, adjustments can be made to ensure an even and efficient spread pattern.
Accu-Spread is a key component of the Fertcare initiative. An Accu-Spread tested machine and a Fertcare trained operator is an essential part of best practice fertilizer use.
The Accu-Spread testing process involves driving the spreader machine over a line of 50 equal-sized collection trays, while discharging product. |

The machine passes over the trays three times and the contents of each collection tray are then weighed (noting the location of each tray in relation to the centre of the spreader). The data is then entered into a computer and a graph is created, showing the spreading pattern in terms of width and quantity of product. Based on a variation target of less than 15%, a recommended spreading width is also determined for the machine.
Once a machine has been tested and accredited, certificates showing the spread pattern are issued and are available to customers. This allows farmers to know exactly how their fertilizer is being spread. Farmers should look for Fertcare accredited businesses, staff and machines to ensure best practice supply, advice and application.
To arrange to have your spreader tested and accredited, please contact one of the approved testers listed in the document below, or the AFSA National Secretary, Neil Henry on (03) 5577 4218.
A full list of accredited spreaders, and a media statement about the program are available below.
