Considerable interest in trends taking place in the consumption of commercial fertilizers in Kentucky has been evident during the last two or three years. Due both to the stressed agricultural economy and to government programs, total tonnage has dropped significantly. This has made a direct impact on the fertilizer industry serving Kentucky. Concern has been expressed that UK is "telling farmers that they're using too much fertilizer", suggesting that this is the cause of the reduced volume experienced by many dealers. We hope to address this concern in such a way that UK's position regarding use of commercial fertilizers for crop production can be better understood.
