in low exchangeable potassium levels. 68 As potassium is removed from exchangeable or solution phases, a shift of potassium from slowly available forms to readily available forms occurs. On the other hand, if the K+ ion concentration of the soil solution and exchange complex is increased by adding potassium fertilizer, the reverse is true.

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.
