Our advice centre has all the information you’ll need about choosing and using fertiliser from Glasson.

Using the right fertiliser is fundamental to crop quality and yield, and at Glasson Fertilisers we can help you through every step of the process.

We work with our customers to help drive efficient nitrogen use, and ensure you only apply what your crop needs. Our bespoke blends release nutrients in a targeted way, improving both efficiency and return on investment.

We offer a full soil analysis service for all crops, and our FACTS qualified advisers can help you create a bespoke fertiliser plan to suit your requirements.

Our products are made from well-sourced raw materials and our strong supply chain relationships help us guarantee the exceptional quality of our product range.

Our plants are equipped with the latest manufacturing technology, helping to ensure superior product quality. Efficient mixing, oil coating and screening of our fertilisers all mean that they reach you in perfect condition. We regularly analyse the nutrient content of our blends and our production technology is maintained by our team of specialist engineers to ensure our products meet the high standards we expect.

Our bespoke, durable packaging combines a sturdy outer layer with a weather-proof inner lining to ensure product is well protected and easy to handle. Bag weights are checked and recorded during every production run, and wagons are weighed in and out of site.

We have a 48-hour factory-to-farm policy, meaning our products are never stored beyond longer than necessary. Unlike other suppliers, all our blends are made to order, meaning the product you receive on farm is in the freshest and best possible condition.

We have a strong network of hauliers, ranging from local carriers to nationwide distributors. Our dedicated transport team and strategic plant locations means we can guarantee fast response delivery, and we can supply your fertiliser on an artic or rigid wagon. All our hauliers are FIAS accredited.

We believe in quality assurance and product security, and that’s why we can trace your blend back from the farm to the hour it was made. Analysing and managing every aspect of the supply chain allows us to be in control of the quality of the product and means our fertiliser can reach you in the finest and safest condition.

We recognise that building a successful partnership requires more than great quality products. With this in mind, our experienced and helpful staff are dedicated to supplying a personal service and unrivalled after sales support.

Every step of the supply chain is accredited by the Fertiliser Industry Assurance Scheme. FIAS was launched to assure fertiliser security and traceability in the industry supply chain, and is managed by the Agricultural Industries Confederation (AIC). More information on the scheme can be found here.

Just as important as choosing the right fertiliser for your crop, the best results are achieved by the nutrients being applied accurately and evenly across the field.

For best results we would always recommend tray-testing fertiliser prior to application, but guideline spreader settings for some of our products are available in the links to the spreader manufacturers databases below:

Glasson Fertiliser is a committed member of the Fertiliser Industry Assurance Scheme.

FIAS was launched to assure fertiliser security and traceability in the industry supply chain and is managed by the Agricultural Industries Confederation (AIC).

All customers should follow the AIC 5 Point Plan when purchasing and storing fertiliser.

  1. Wherever possible use a Fertiliser Industry Assurance Scheme (FIAS) approved supplier.
  2. Wherever possible keep in a secure area such as a building or sheeted away from public view.
  3. Carry out regular stock checks and report any loss to the Police immediately (call 101)
  4. Avoid leaving fertiliser in a field overnight – never leave fertiliser in the field for a long period of time.
  5. Remember it is illegal to sell ammonium nitrate without the correct documentation.
