Given the encouraging outlook for the potash industry, many investors are interested in entering the space. One popular way to do so is by investing in potash stocks. There are a huge number of companies to consider, so it's important to do your research. Investors often choose to begin with large producers — in the potash sector, some of the biggest players are Nutrien (TSX:NTR,NYSE:NTR), Mosaic (NYSE:MOS) and K+S (OTCQX:KPLUF,ETR:SDF). Our lists of potash companies on the TSX and TSXV, as well as on the ASX, are also good places to start.
