Guano as a natural resource (1 Viewer)

[sarah-jne]

does anyone kno stuff about research into possible future replacement materials for superphosphates (which replace guano)

also, why is superphosphate a suitable replacement? what properties etc? limitations?

thanks

is superphoshpate really a shrinking world resource? i don't think so. guano probably is. superphosphate is a fertiliser - just like guano. BUT guano is an organinc fertiliser, superphosphate is an inorganic one.

if guano is your diminishing resource, then superphosphate and other alternatives to it are what you need info on.

But surely one day we will run out of phosphate rocks...
