Phosphorus 12.7% | Sulphur 1.1% | Calcium 35%
Highly soluble: (Citric solubility 41% Formic solubility 73%)
BioAgPhos is made from highly reactive, high-grade reactive phosphate rock (RPR) combined with BioAg’s microbial digesting agent.
Long-lasting, sustained release of nutrient making both annual and biennial (every second year) applications possible.
The basis of BioAg’s solid fertiliser range
BioAg’s solid fertiliser range is based on BioAgPhos
The result a fertiliser range that is less reliant on rainfall to be plant available.
By replacing water solubility with microbial digestion, we have reduced the amount of nutrient in soil lock-up, and provided a fertiliser range that can be spread at any time of the year.
Around one third of the phosphorus and calcium is immediately available, while the remainder is slowly digested and released, allowing for annual or every second year fertiliser application.
Independent analysis shows that 100% of our phosphorus is bioavailable.
Features and benefits include:
- reduces fertiliser loss due to common issues such as leaching and lock up
- small particles enable even distribution – very important as P is not mobile in soils
- safe for use on all areas on your farm, including waterways which will simply grass up
- a natural and sustainable alternative to conventional fertilisers.

Restore the soil's natural balance.
BioAgPhos doesn't just fertilise soils - it charges the soil's natural fertility and structure. BioAgPhos is a unique, biologically active phosphate that has been treated with a proprietary microbial culture.
P is available to plants immediately and over time. Depending on your soil's requirements, BioAgPhos may only need to be applied every second year. Talk to your local BioAg area manager about switching to BioAgPhos for better soils.

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.
Being a mineral, composition and reactivity can vary greatly. Read more about their differences and how to improve phosphate availability.
