Another angle: Rock phospate (and thus all those phosphorus products) is a
limited resource only found in a few places on earth (florida, morocco, ??).

Idaho, some islands off of Spain -

Florida, North Carolina, Tenessee, Idaho and Utah, apparently; probably other
Southern states.

Florida and North Carolina account for 85% of US phosphate rock production.
This is pretty scary because I've seen open pit phosphate mines in Utah and
they are frickin' enormous, thousands of feet across. So I'd hate to see the
scale of the mines that do the real production. Another good reason to try
to generate and recycle your own nutrients. Just because organic
certification okays the use of rock phosphate doesn't mean it isn't damaging
to the planet.

Better to promote the use of it in its natural form in agriculture than to
worry about
the mining process; if you're going to have it to put in your garden then
someone has to
extract it and deliver it to you, and profitably. The best US phosphate, Carolina Black is unavailable because the Canadian mining company that bought it will not sell the pulverized raw ore to anyone. They slammed the door in the faces of all US organic and sustainable farmers and organic fertilizer blenders and manufacturers
(Fertrell and ErthRite). People have gone to the top of the company to plead
for sale of CRP as in the past, to no avail.
Instead it is reserved for the manufacture of phosphoric acid for use in commercial fertilizers, soft drinks, detergents (?) and rust removal and a myriad of other industrial uses and products. Wasted on cokes and pepsis for the fools.
