If there’s one business out there that has been a consistent winner, one that also happens to be a great green play, it’s agriculture. Cramer’s top three ag stocks – Potash , Mosaic and Agrium – are up an average of 643% since he first got behind all three back in October of 2005. Agribusiness is a long-term theme, he said on Monday’s show. In particular, fertilizer stocks have been a great way to play this bull market thanks to demand outpacing supply and thus leading to higher prices.

That’s why Cramer is now getting behind Intrepid Potash, a fertilizer IPO set to price on Friday that is 100% levered to potash, a crucial component of fertilizer. The world’s largest potash producer, POT, is only one-third potash despite its name. IPI will be the first Western pure play on the substance and it just so happens to have much lower production costs than POT.
