Hmm I found that very hard to believe, from everything I looked up we still have 250 years of potassium in reserve ready to be mined lol Idk one of us found incorrect information and yours is harder to believe i'm leaning toward that being wrong..
My bad! I had that wrong......I should have said Phosphorus, and that's the available amount left in the US!
That's what I get for listening to my Partner and not investigating it for myself!
You sir are total correct!
I apologize to all who may have been misled!
Here is an "out-take" from a report on the Phos. for the facts.
Ninety percent of the phosphate rock reserves are located in just five countries: Morocco, China, South Africa, Jordan and the United States. The U.S., which has 25 years of phosphate rock reserves left, imports a substantial amount of phosphate rock from Morocco, which controls up to 85 percent of the remaining phosphate rock reserves. However, many of Morocco’s mines are located in Western Sahara, which Morocco has occupied against international law. Despite the prevalence of phosphorus on earth, only a small percentage of it can be mined because of physical, economic, energy or legal constraints.
In 2008, phosphate rock prices spiked 800 percent because of higher oil prices, increased demand for fertilizer (due to more meat consumption) and biofuels, and a short-term lack of availability of phosphate rock. This led to surging food prices, which hit developing countries particularly hard.
