Important Information

  • Benefits

    Due to the slower release nature of the phosphate in dicalcic trial work has shown this fertiliser can be of benefit in high leaching environments such as on West Coast sands and podzols and the Wharekohe soils of Northland.

  • Uses

    Ravensdown Dicalcic Phosphate is commonly used for direct drilling; dicalcic alone will not cause germination injury at normal rates of application. It can also be used for maintenance as it contains phosphate and sulphate and will also raise soil pH.

    The phosphate in dicalcic has been reverted from monocalcium phosphate to dicalcium phosphate. This takes longer to become fully plant available and can provide a slower, continuous release than superphosphate.

  • Application

    Actual spreading rates will vary according to farm type, climate, productivity and soil type. Soil testing and fertiliser plans are available to ensure you use the right product at the correct rate. Call our Customer Centre for information.

    As with most solid fertilisers, Dicalcic Super can be stored over a season as long as it is kept in a cool, dry, well ventilated area.
