Lecture 12 b Soil Cation Exchange Capacity - SlideServe

Let’s Talk About an Overlooked Soil Metric: Cation Exchange Capacity (CEC) We often focus on soil pH, NPK values, or organic matter content, but one of the most underrated measurements in soil chemistry is the Cation Exchange Capacity, or CEC. In simple terms, CEC tells us how well a soil can hold onto and exchange positively charged nutrients ions like calcium (Ca²⁺), magnesium (Mg²⁺), potassium (K⁺), and ammonium (NH₄⁺). Think of soil particles as tiny magnets. The stronger the magnet (higher
