Somiphos Black Phosphate Rock is naturally mined phosphorus from Algerian ground mineral deposits that is used as a slow-release phosphate fertiliser.
This product maintains optimum pasture growth by releasing plant-available phosphorus at a consistent rate for plant uptake. It has exceptionally low cadmium levels, reduces liming requirements and has a higher P value than Superphosphate often resulting in a decrease of P expense. This product can be applied conventionally or organically certified.
