Potash (or carbonate of potash) is an impure form of potassium carbonate (K2CO3) mixed with other potassium salts - it's kind of a generic term to used to describe various types of mined material. It's a major component of fertilizers - if you look on the bag of lawn fertilizer you buy this spring, potassium is the third mineral listed on the ratio mix (nitrogen/phosphorus/potassium). <br /> <br />Most of the potash in North America is mined in Western Canada. What you're seeing are trains moving off the CN and CP to Chicago area interchange for forwarding to fertilizer plants all over the eastern USA. As an example CP/CSX/Indiana & Ohio move eight or twelve unit trains a year to the Royster Clark fertilizer plant in Washington Court House, Ohio - which gives us a change to see CP units here in the wilds of Suthern Ahia!.
