S10 BioAgPhos

Incorporates elemental sulphur in the form of sulphur bentonite in BioAgPhos. Ideal for higher rainfall and higher leaching environments.
Phosphorus 11.4% | Sulphur 10.0% | Calcium 32.0%

Highly soluble, with a minimum of 35% citric acid and 65% formic acid solubility. S10 BioAgPhos is an immediate and sustained release phosphate fertiliser made from high-grade reactive phosphate rock composted with BioAg’s proprietary phosphate digester.

Elemental sulphur, in the form of sulphur bentonite, provides crops and pastures with a sustained release form of sulphur for the entire growing season. Independent analysis shows that 100% of the phosphorus is bioavailable / plant accessible.

  • A natural and sustainable alternative to conventional fertilisers
  • The inclusion of sulphur improves cycling and uptake of other nutrients such as phosphorus and nitrogen
  • Sulphur is essential for plant growth, the formation of root nodules on legumes, and improves plant health
  • Delivers immediate and sustained release of phosphorus making both annual and biennial applications appropriate
  • Reduces nutrient losses due to common issues such as leaching and lock up
  • Can be applied at any time of the year.
  • 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
  • S10 BioAgPhos is a certified organic input.

  • Kangaroo Island independent trials

    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 ...
