It’s well known that agricultural activities remove phosphorus (P) from the soil profile. Phosphate (P) requirements for crops and pastures using Direct Application Phosphate Rock (DAPR) represents a very affordable, long-term investment opportunity to increase the nutrient bank of soil.

It’s environmentally friendly and a long-term source of slow-release P that may assist to strengthen biotic microbial activity and release additional tied-up nutrients. DAPR is better suited to high rainfall areas with acidic soils and may provide additional pH buffering.

Proper soil tests are invaluable and a cost-effective tool to identify how your crop or pastures yields can benefit from DAPR.
DAPR application rates need to be determined in consultation with your professional agronomist, as it will differ for each soil and crop type.

Phosphate rock can equally be applied in conjunction with Single Superphosphate to provide a combined immediate and long-term benefit.


Agriflex currently have large quantities of crushed (<4mm) phosphate rock available in Mt Isa, Queensland.
