Conditions For Mixing Although Dicalcic Phosphate generally mixes well with other products, it is not compatible with the following: Potassium Nitrate, Ammonium Nitrate, Mono Ammonium Phosphate (MAP), Cropmaster DAP, Calcium Ammonium Nitrate (CAN) or Urea Dicalcic Phosphate can be compatible with the following under certain circumstances: Flexi-N (magnesium coated Urea) and Ammonium Sulphate Granular Segregation may occur when mixed with product with differences of particle size.

Superphosphate which has been slurried with (normally) 50% lime
Combines both a fertiliser source with a lime source
Used as a maintenance fertiliser as it contains phosphate and sulphate and also raises soil pH
Safe to drill directly with seed as will not cause germination injury
The form of P in dicalcic has been reverted so takes longer to become fully plant available in the soil compared with superphosphate
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
Dicalcic Phosphate is Superphosphate which has been slurried with (normally) 50% lime. It may be used as a maintenance fertiliser as it contains phosphate and sulphate and will also raise soil pH. The form of phosphate in dicalcic has been reverted from monocalcium phosphate to dicalcium phosphate and this takes longer to become fully plant available in the soil compared with superphosphate. Dicalcic alone is a safe fertiliser to drill directly with seed and will not cause germination injury at normal rates of application.
Application rates and advice
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.
Mixes well with most other products such as potash, but not with urea and other N fertiliser as for superphosphate.
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.
