PotPhos with SoP

Incorporates BioAgSoP and BioAgPhos in a blend ideal for soils that need phosphorus, sulphur, and calcium, such as pastures and grazing.
Phosphorus 10.0% | Potassium 10.0% | Sulphur 5.0% | Calcium 26.0%

Immediate and sustained release phosphate fertiliser made from high-grade reactive phosphate rock, composted with BioAg’s proprietary phosphate digester, and combined with sulphate of potash to provide potassium and additional sulphate sulphur. Phosphorus, 0% water-soluble, and a minimum of 35% Citric Acid and 65% Formic Acid solubility

A fertiliser suited to all grazing systems where potassium (K) inputs are required, and organic or low chloride inputs are preferred. Ideal for post hay or silage removal or for light soils that struggle to hold potassium and sulphur for extended periods.

  • A natural and sustainable alternative to conventional fertilisers
  • Sulphur is essential for plant growth, the formation of root nodules on legumes, and improves plant health
  • Delivers immediate and sustained release of phosphorus
  • 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
  • PotPhos with SoP is a certified organic input.
More information

Potassium plays a vital role in photosynthesis, starch accumulation, protein synthesis, controlling ionic balance within the plant, metabolism of carbohydrates, disease suppression, and improving the plant’s ability to withstand drought and frost tolerance.

Potassium deficiency frequently occurs where there is a gradual decline in soil potassium levels over time or through the introduction of crops with high potassium requirements into a rotation, like legumes. Read more about Potassium deficiency.

  • Reactive phosphate rock fertilisers

    The right phosphate rock, used effectively, is an excellent source of long lasting and non-polluting phosphates. The quality of phosphate rock and its suitability for use as a fertiliser varies from deposit to deposit and may also vary within a single deposit. There may...

  • '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 ...

  • Potassium deficiencies

    Potassium (K) is an essential nutrient for plant growth and development. Because large amounts are absorbed from the root zone in the production of most crops and pastures, it is classified as a macronutrient. Potassium has many functions within the plant; including pho...

  • 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...
