Why Use Triple Superphosphate?

Triple Superphosphate is best suited to applications when there is a limited requirement for nitrogen and sulphate sulphur. Triple Superphosphate should also be considered as a phosphate source when freight and application costs are high such as aerial application jobs.

The benefits of using Triple Superphosphate are:

  • A cost-effective, high analysis form of water-soluble phosphate, allowing you to apply more P for less cost.
  • Contains a higher P content compared to common alternatives, resulting in significant savings on freight and application costs
  • Contains only a small percentage of sulphate making it a cost-effective and agronomically suited phosphate fertiliser for areas that do not require sulphur. Alternatively when sulphur is required Triple Superphosphate can be blended with Elemental Sulphur to cater for long term sulphur requirements.
  • Triple Superphosphate is granulated and blends well with the majority of other fertilisers. Blend with Dickie Direct’s Granulated RPR to produce the perfect balance of water soluble and non-water soluble P for your soil type and farming operation.
  • Contains less cadmium and other heavy metals compared to other more common phosphate fertilisers. This makes it an ideal substitute for areas that already have or are developing production limiting heavy metal levels.

When to Use

Summer, Autumn, Spring


When applying larger phosphate applications water soluble phosphate such as that contained in TSP can lose efficiency in some soil types that have a limited ability to hold onto phosphate. In these situations we recommend blending TSP with a non-water soluble form of phosphate such as DDPhos Granulated RPR. For more information speak to your Dickie Direct Area Manager.

Phosphorus’s Role in Plants

  • The most important role of phosphorus is the storage and transfer of energy that is generated through photosynthesis along with the metabolism of carbohydrates.
  • Phosphorus is an essential compound of Adenosine Triphosphate (ADP), the energising component driving plant development.
  • Phosphorus deficiency has a huge impact on plant growth and reproduction, reducing the plant processes noted below.
  • Processes aided by phosphorus:
    • Large root growth
    • Early formation of plant shoots
    • Improved stalk and stem strength in crops
    • Improved fruit, vegetable, and grain quality
    • Seed formation
    • Resistance to moisture and colder temperatures
