University-established critical levels have been instrumental in guiding fertilizer decisions to maximize yields. However, many of those critical levels were determined 10 to 20 years ago and, therefore, don’t take into consideration the potassium demand rates of today’s new hybrids, varieties and production practices. It’s important to assess your operation, what you grow and what your potassium needs are to ensure you apply the K needed this fall to maximize yields next fall.

If you’re using new hybrids, varieties or practices, you may need a lot more k than you might think.
