On CNBC's "Cramer's Stop Trading" segment, Cramer acknowledged that the analyst did not lower his price target on shares of Potash, but suggested that this year's "bountiful harvest" would be a negative.
Prices of corn, wheat and soy are all "getting killed," while other commodities like natural gas are at six-month lows. Many also believe that gas prices have already peaked for this summer, he said.
Cramer suggested investors avoid Potash and Mosaic (MOS) at current levels, as input costs for crops continue to drop.
Cramer also acknowledged General Mills' (GIS) "terrific dividend" and strong cash flow, while pointing out how well the stock bounced back following its analyst meeting.
