Phosphorus (P) is a non-renewable resource with peak Phosphorus (half-depletion of known global reserves) predicted to occur between 2040 and 2060.  On the other hand, P levels in agricultural soils are rising because most of the P applied as synthetic fertiliser (80-90%) is sorbed by soil particle rendering it temporarily or permanently unavailable to most of our important crop species. The challenge ahead is to utilise and responsibly manage all P fertiliser resources, producing healthy crops and animals while meeting the needs of a growing population. BioGuano™ represents a viable natural option to synthetic P fertilisers. The unique combination and forms of plant-available Phosphorus, Calcium and Silicon helps in several ways to protect and extend Phosphorus nutrition.
