Potassium Management In Oklahoma’s Expanding Cotton Crop
Dr. Cristie Preston and Dr. Brian Arnall discuss cotton’s expansion in Oklahoma and the importance of adequate potassium fertilization. Potassium is a key nutrient for boll load, root expansion, water use efficiency, and overall plant growth. If a cotton plant is stressed due to potassium deficiency it can lead to smaller root growth and cause the plant to be more susceptible to pests and diseases. To help determine the nutrient need for cotton and other crops, eKonomics offers free ROI tools like the nutrient removal calculator.
