A soil with a low pH does not use fertilisers efficiently. A soil at pH of 5.9 has the potential to lock up 48% of phosphorus and reduce nitrogen utilisation by 11%. Considering both farm profitability and environmental sustainability fertiliser must be utilised efficiently, Calcifert products can help achieve this aim.

Agricultural and horticultural nutrient

Calcifert Lime, our fast-acting agricultural granulated limestone, is extremely popular with farmers, as are our Calcifert Sulphur and Calcifert Mag products which supply much-needed nutrients to the soil.

You can optimise the nutrients in your soil with our range of granulated lime, magnesium lime and calcium sulphate products that have:

  • Low application rates
  • Highly reactive granules
  • Applied with a standard spreader

All of our range is designed to be implemented via a conventional fertiliser spreader, making it quick and easy to treat either whole fields or specific areas. Calcifert supplies a range of easy-to-apply granulated products for the agricultural and horticultural sectors.

Calcifert origin

Our fertiliser range is best known for its flagship granulated lime product, Calcifert Lime, a highly reactive and pure agricultural lime product, made using 100% British lime from the Peak District. This lime is well-proven to effectively reduce soil acidity and regulate pH in grassland and arable soils.

We make Calcifert Sulphur from a source which supplies Calcifert with Calcium Sulphate, which has a 98% purity.

Calcifert specifications

LKAB Minerals makes all products for high purity sources using a water-soluble organic binder. For detailed information, please see our specification sheets and PSDS.

Accreditation

Calcifert products are accredited with the AgLime Quality Standard (AQS), an industry initiative targeted to guarantee the regulatory quality of AQS certified agricultural liming products on the UK market.

You can apply our Calcifert products via a conventional fertiliser spreader. Independent tests have shown that Calcifert granulated products can be accurately spread up to 36-metre bout widths.

Spreader setting results

Trials with a range of leading fertiliser spreaders have shown that Calcifert Lime spreads to 36 metres and has a Co-efficient of Variance of less than 3.7%.  We have tested:

  • Amazone ZA-M
  • Kuhn Axis
  • KRM Ex trend
  • Vicon RSXL

Calcifert Lime+BZn and Calcified Lime+ have the same product characteristics as Calcifert Lime, and we recommend following the same spreader setting for these products.

Calcifert Sulphur has a similar spread pattern and has been separately tested with a range of fertiliser spreaders. For Calcifert Sulphur+BZn and Calcified Sulphur+ products, we recommend using the Calcifert Sulphur spreader settings.

Trials with Calcifert Mag show that this product successfully spread to up to 36-metre bout widths.
