History and Prospects of Potash Application in China

Efforts have therefore been made to lessen dependence on imported K. Potash is mined in China in salt lakes but in relatively small amounts. K production in 1980 was only 20 000 mt but has increased rapidly and by 2005 was supplying 2.54 Mt constituting 37 percent of the country`s use.
