BioAg Superb

Incorporates calcium sulphate in the form of gypsum in BioAgPhos. Ideal for soils that need phosphorus, sulphur, and calcium, such as pastures and grazing, and for crops requiring extra sulphur, such as canola.
Phosphorus 8.4% | Sulphur 6.9% | Calcium 31.0%

Phosphorus 0% water-soluble and a minimum of 35% Citric Acid and 65% Formic Acid solubility. Immediate and sustained release phosphate fertiliser made from high-grade reactive phosphate rock, composted with BioAg’s proprietary phosphate digester. Combined with gypsum to provide additional calcium and sulphur in readily available forms.

  • A natural and sustainable alternative to conventional fertilisers
  • Annual and biennial applications are appropriate
  • Reduces nutrient losses due to common issues such as leaching and lock up
  • Safe for use on all areas, including waterways
  • Small particles enable even distribution; beneficial given P is not mobile in soils
  • Well suited to blending with ameliorants such as lime, gypsum, and compost
  • Independent analysis shows that 100% of the phosphorus is bioavailable / plant accessible
  • Can be applied at any time of the year
  • BioAg Superb is a certified organic input.

  • Kangaroo Island independent trials 2020

    Replicated trials being held at Stokes Bay and Parndana on Kangaroo Island have supported results to date showing BioAg’s immediate and sustained release fertilisers are as effective, and potentially better performing, than Single Super Phosphate (SSP). Using BioAg’s Su...

  • Reactive phosphate rock fertiliser

    The phosphate rock used in agriculture is known by a number of names. Reactive phosphate rock (RPR), direct application phosphate rock (DAPR), mineral phosphate, soft rock, hard rock. Variants on all of these are names or brands used across the fertiliser industry. Phos...

  • Measuring P in soils when using natural phosphate fertilisers

    The Olsen and Colwell soil tests are strongly correlated when using water soluble/chemical fertilisers. However, these tests will likely underestimate plant available phosphorus (P) when fertilising with natural fertilisers such as RPR or BioAgPhos. P is an important el...

  • 'Super' or reactive phosphate rock?

    What is superphoshate? Superphosphate, ‘SSP’ or ‘super’ is a fertiliser processed using sulphuric acid to boost the water solubility of phosphorus. Various strengths of P plus additions of nitrogen make up a range of products that feature a high proportion of nutrients ...
