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.

PotPhos with SoP resources
- Soil-nutrient relationships
Nutrients, such as calcium and magnesium, may be supplied to plants solely from reserves held in the soil. Others like phosphorus and nitrogen are added regularly to soils as fertiliser to be withdrawn as needed by crops.
- Challenging terrain
Since the 1950s, fertiliser and ameliorants have been spread using planes and more recently helicopters. In hilly and remote terrain this is common, allowing farmers better use of more of their land. While sometimes it isn’t easy to locate someone to do aerial spreading...
