Fertiliser Spreaders
Fertiliser Calibration
Fertiliser spreader calibration is a very important task. There are a range of apps available for certain makes and models of spreaders and it is advised that if there is one available for your machine then you should download and use it. Unfortunately not all machines will have apps available.
Fertiliser Calibration tool
This tool has been developed to help people using such machines to calibrate their machine. Simply use the sliders to input the information such as forward speed, working width and desired application rate and the calculator will give the flow rate for the fertiliser spreader. You can then check your actual flow rate by collecting fertiliser from the machine for a period of 1 minute and compare your output. Adjust the fertiliser shutter position if needed and check again.

It explains in a simple format the basics of setting up a fertiliser spreader, calibration method for most twin disc spreaders, as well as the characteristics of fertiliser and how they can be assessed. There is also a section which looks at the latest fertiliser spreader technology.
