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.

Calcifert origin

Calcifert 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.

We have gathered a range of different projects and created a Case Study for each of these. Of course, our experience is more extensive than we can present here. You can always contact us for technical advise tailor-made for your situation.

  • Grass Silage Case Study
  • Regular applications Case Study

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.

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.
