phosphorous is in short supply for use in fertilizers at this time. Canadian wheat crops are in danger due to this shortage as are other nations crops as well. Some have even taken to gleaning  it from old color TV sets! It may soon be as expensive as is oil now!

The conversion of P2O5 to P was incorrect

Ore grading 1.7% P2O5, %P is 1.7%x(62/142) = 0.74% P



This is about 10 times higher than would be acceptable to steelmakers
