Calibration and Spreaders

CF Fertilisers recommends that with each new spreading season you have your spreader calibrated.

Remember set your spreader for application rate and spread pattern before use.

See the SCS spreader and sprayer testing video below for more information on how to set up a fertiliser spreader correctly.

No matter how good the fertiliser plan, inaccurate spreading will result in higher environmental impact, reduced yields and ultimately lower profits.


Calibration Benefits 

We recognise the importance of maximising the effectiveness/ value of fertiliser and work closely with the calibration specialists SCS Spreader & Sprayer Testing Limited who offer a reliable, well organised calibration service. 

Spreader Testing can help with:

  • accurate spreading in terms of both rate and evenness of spread,
  • even if striping is not visible, crops losses could be considerable,
  • accurate spreading ensures maximum yield and ripening and fewer harvesting difficulties.

Accurate spreader settings, correct application rates and a thorough inspection of the machine make the service good value for money.

Spreader Manufacturers 

CF Fertilisers also liaise closely with spreader manufacturers to ensure that spreader settings are as up-to-date as possible. This is achieved by annually providing fertiliser for spreader manufacturers to assess at their test halls in Europe. The test hall determines, under controlled conditions, the spreader settings for each machine at all spreading widths; they are then published in their handbooks and on their websites.

CF Fertilisers strongly recommends that you set up your spreader for both application rate and spread pattern.
