Cation Exchange Capacity (CEC) is a basic soil concept that can play a major role in nutrient management. Soils naturally carry a net negative charge that holds cations in an exchangeable form. In general, an increase in clay and organic matter, the CEC increases and the total cations that can be held. What does this mean for fertilizer and other management practices? Watch the recording of this webinar by Dr. Cristie Preston to gain knowledge about soil CEC to can help inform your nutrient management decisions to maximize fertilizer inputs.
