Fertiliser Products


The fertiliser business of the Wynnstay Group has grown significantly over the last few years. As one of the largest merchants in the west of the country the company plays an important role in the distribution of a broad range of products from manufacturers and blenders.

Wynnstay markets its blended range of fertilisers under the “Top Crop” name which allows us to not only provide the most popular and commonly used grades but also prescription mixes to suit all crop and soil requirements.

Customers can benefit from the scale of operation in competitive pricing and the provision of comprehensive advice from FACTS registered personnel.

Balancing nutrient input with crop output has always been important but with the financial constraints and the increasing environmental pressure on the industry even more emphasis is being put on choosing the best fertiliser programme for each farming system.

In addition to our Top Crop range we can also provide a range of products from both the Soil Fertility Dunns range that includes GAFSA Basic Powder and Phosmin granular and from Hatcher’s we can offer Fibrophos concentrated PK fertilisers.

This is by no means an exhaustive list and if you have a particular problem in any type of crop we can help in coming up with a solution for you.

CF Fertilisers

Focusing on quality, reliability and best practice

CF Fertilisers is the UK’s premier fertiliser manufacturer and a major supplier of process chemicals and utilities.

At the heart of the business are three key drivers:

  • Technical excellence
  • Social and environmental responsibility
  • Innovation and product development

The result:

  • High quality products
  • Professional technical advice
  • Reliable services

This means CF Fertilisers is committed to British agriculture making investment in production capacity and Advice and Services fundamental to the company’s success. Fertilisers must be used accurately and at optimum rates. Over application means farmers waste money and can have a negative environmental impact.

When fertilisers are used efficiently the benefits are immense:

  • Crop and grass yields can be increased
  • P and K indices are maintained at levels which support healthy growth
  • Reduced Nitrogen or Sulphur is at risk of leaching into the environment

As the UK’s only manufacturer of straight Nitrogen, Nitrogen/Sulphur and quality True Granular Compounds – as well as the leading advocate for fertiliser Advice and Services – CF Fertiliser is at the heart of British agriculture.

Made from fine limestone flour combined with a water-soluble organic binder, Calcifert® is produced in the UK from limestone mined in the Peak District.  Hard limestone granules of a regular size and shape ensure an even spread and rapid uptake.

Calcifert® is easy to spread with a conventional farm spreader – no need for specialist contractors – and lower application rates than conventional lime make Calcifert a cost effective option.
