Welcome to Phosta, suppliers of premium grade natural guano phosphate.
Phosta is a 100% natural product derived from natural deposits of fossilised Guano phosphate. It is produced through the decomposition of accumulated sea bird droppings, bat droppings, carcasses, shells and animal bones. Mined from caves in Central Java Indonesia, our naturally occurring, premium grade guano phosphate is Bio-gro certified, highly effective and safe.

With its high P content, sustained plant availability and resistance to run-off, Phosta offers the best of both worlds to anyone looking for a genuine alternative to superphosphate or RPR.
