The potash market is looking strong today thanks to news of increasingly positive supply and demand fundamentals. Potash Corp. (NYSE:POT) is leading the charge.

We have no shame here at Notes. When legendary underground investor Jim Rogers makes a call we listen. And we listen good.  Rogers correctly predicted the commodities rally in 1999. And between 1970 and 1980, when he partnered with George Soros at the Quantum Fund, his portfolio made gains of 4,200% when the S&P 500 rose by 47%. To say he’s a legend is an understatement.

Did you miss out on buying Apple (Nasdaq: AAPL) at $80 or $90? How about The Mosaic Company (NYSE: MOS) for $25? While investors worry about missing out on stock market rallies, there’s another equally important event: Buying on stock market dips.

Time to Load Up on Fertilizer Stocks? Springtime is usually the season when the farming community begins to spread fertilizer on their fields.

We haven’t yet seen the worst of this credit crisis, says Chris Mayer. A lack of funding is forcing farmers to reduce crop planting. And that will soon send commodity prices soaring again. Chris finds five beaten-down fertilizer and irrigation companies that will benefit as agriculture rebounds.

According to AP, potash producers will continue on their impressive uptrend because demand for fertilizers still exceeds supply.

But Andrew Mickey says the soaring price of natural gas will hit fertilizer manufacturing profits hard — and hurt potash stocks in the process.

In the last twelve months, two leading potash producers, The Mosaic Company (NYSE: MOS) and Potash Corp (NYSE: POT) have seen share prices rise 260% and 176% respectively.
