Frequently Asked Questions

How long does a tray test take?

This depends on the quality of the product and the working order of the machine, wider spread widths usually take longer. If everything is ready for testing, machine is on the tractor, fertiliser is nearby, depending on the number of tests, 2-3 hours would be an average.

Where is the best location for a tray test?

A well sheltered, level field, preferably close to where the fertiliser/spreader is stored.

What do I need for the tray test?

1. Fertiliser Spreader
2. Fertiliser (still in the bag, not in the hopper)
3. The usual operator, having someone who knows their way around the tractor/spreader will speed up the test.

Do I need to be present for the tray test?

Ideally we would want to test with the usual operator, having someone who knows their way around the tractor/spreader will speed up the test.

Are there any discounts available?

We discount multiple machine testing by 10% for 2 or more machines. This can be increased by a further 5% if you are a member of any of the Buying Groups we work with. For testing more than 4 machines on the same day and at the same location, discount subject to prior negotiation with SCS. This is not limited to spreaders; you will also get the discount for testing sprayers, granular applicators or slug pelleters on the day. This discount is not only limited to your machines- why not get your neighbouring farmers together to reap the benefits of a discount?

How often do I need a test?

We are not out to get you to test every year, just get tested when you need it. These are our golden rules for knowing when to get tested.
If you are using different fertiliser, you should get tested annually.
If you are using the same fertiliser and spreading more than 100 tonne, you should get tested annually.
If you don’t fall into these categories you should get your machine tested every other year.

Are all SCS tests official NSTS reports?

All SCS testing meets the requirements of the NSTS. We can NSTS certify your sprayer, slug pelleter, granular applicator and fertiliser spreader. The NSTS certification costs £27 per machine on top of the test fee.
