The objective of this talk is to present summaries of several potassium related studies, including the yield response of several cotton varieties to foliar potassium under low-K soils, differences among soils on their ability to hold and release potassium, and the potential use of VERIS-EC readings to help explain the variability in yield response to potassium fertilization.
