Adequate potassium nutrition for soybean is critical to promote maximum agronomic productivity. Most land-grant universities provide potassium recommendations for soybeans, but some consultants, policymakers, and producers may not be aware of how those recommendations are determined. The goal of this presentation is to provide some background on how potassium behaves in the soil, how soybean plants take up potassium, what potassium does in the plant, and how universities determine potassium recommendations.
