The soil cation exchange capacity (CEC) is the ability of soils to bind and store a particular group of nutrients by electrical attraction, those that form positively charged cations, such as calcium (Ca2+), magnesium (Mg2+), potassium (K+), and nitrogen in the form of ammonium (NH4+). Soils are composed of a mixture of sand, silt, clayContinue reading “What is Soil Cation Exchange Capacity (CEC)?”
