Although several nutrient deficiencies appear in Tennessee's cotton‐producing region and throughout the U.S. Cotton Belt, potassium (K) deficiencies remain the most relatively unpredictable and common. The objective of this article is to highlight K deficiency symptoms in cotton, summarize the many roles K plays within the cotton plant, briefly summarize K uptake and utilization, and finally describe efforts examining the potential to increase fertilizer K use efficiency.
