Accu-Spread® Model

Accu-Spread® helps optimise the return on fertilizer and machinery investments. Testing involves driving an operating spreader over a line of collection trays, weighing the contents of each tray and calculating the variation in spread pattern to determine an acceptable bout width (distance between the runs). More information on the Accu-Spread Testing Process and benefits can be found here .

Using the Accu-Spread Model, graphs inform the operator the bout width to produce an acceptable spread pattern.

Members (AFSA & Fertilizer Australia members): $15 GST Incl per test Non-Member: $30 GST Incl per test. A test is regarded as one set of tray weights entered into the model to generate a bout width and other graphs. The number of tests is nominated when access to the Accu-Spread model is purchased. The Excel spreadsheet will cease to operate after the nominated number of tests have been entered into the spreadsheet.

Once an order is placed (following successful credit card payment), you will be shown an order confirmation page including purchase codes to activate the spreadsheet. It is important you note these codes and keep them safe.

Anyone is welcome to access the Accu-Spread model and test equipment, however for Accu-Spread certification, equipment must be tested by an authorised Accu-spread Testing Officer. A list of Testing Officers can be found here
