What our customers say

With fertilisers, evenness of spread is critical, especially in horticultural crops. SoilWorx pellets ensure an even spread every time.

Ned English

Customer, Castlecor Potatoes – Mallow, Co. Cork

SoilWorx understands the needs of farmers. From my perspective, and of course organic farmers, SoilWorx helps farmers improve the quality.

Elmer Koomans

Farmer Supplier Fruit Hill Farm – Bantry, Co. Cork

We first used SoilWorx when doing our first reseed in organics. Since then I’ve used it both at reseeds and on established grassland with excellent results. To put it bluntly, I can see the parts I missed with the fertiliser spreader!

The heat treating meaning no weeds which is a game changer especially in an organic system.

Another great point is it can be spread where a slurry tanker or dung spreader can’t get especially in the shoulders of the year when ground is wet. We will continue to use SoilWorx here on our farm.
