Wynnstay Group Plc

- Fertiliser



With the agricultural industry facing growing financial and environmental pressures, the importance of choosing the right fertiliser for your soil has never been more critical. Fortunately, Glasson Fertilisers has the experience and the technology to help. We’ve been producing high quality agricultural fertilisers since 1990 and now supply to merchants and farmers throughout northern England and southern Scotland.

Produced and packed in our modern, purpose built plant, our fertilisers include blended and compounded products for both arable and grassland, and are distributed directly to the farm. Bringing the raw materials straight from the ship to our factory means that transport costs are kept to a minimum, and delivering them directly to the customer eliminates further supply chain costs. These factors produce substantial savings, which, in turn, can be passed on to you.

As a FIAS approved manufacturer you can be wholly confident in our pledge to deliver products and services of exceptional quality, and all at a price that is right for you. We recognise that our success depends on your success, so you’ll find that we are always 100% committed to ensuring that you get the best possible yields from your land. Our blended fertilisers are a mix of nitrogen granules, phosphate granules and potash and will give you the combination that’s exactly right for your needs. You can be sure of an attractive combination of price and performance every time.


Glasson fertilisers are all manufactured at our state of the art production facility on our extensive site at Winmarleigh. With capacity well in excess of 100 tonnes per hour, we can offer fast response times to back up our delivery service especially in peak season.

Most importantly, the plant is equipped with the latest manufacturing technology to give even further improved product quality, through more efficient mixing, oil coating and screening of our fertilisers to ensure that they reach you in perfect condition.
