Potassium for crop production | UMN Extension

Potassium (K) is an essential nutrient for plant growth. It's classified as a macronutrient because plants take up large quantities of K during their life cycle. Minnesota soils can supply some K for crop production, but when the supply from the soil isn't adequate, a fertilizer program must supply the K.
