Cation exchange capacity
Cation exchange capacity (CEC) is a useful indicator of soil fertility because it shows the soil's ability to supply three important plant nutrients: calcium, magnesium and potassium Cations What CEC actually measures is the soil's ability to hold cations by electrical attraction Cations are positively charged elements, the positive charge indicated by a + sign after the elementThe cation exchange capacity (CEC) of a soil is closely related to the soil minerals and texture It is an inherent characteristic of a soil primarily determined by the parent material Soils with higher clay content tend to have a higher CEC and organic matter has a high CEC CEC explained The soil may be considered as a weak electrical system consisting of positivelyCation Exchange Capacity FACT SHEET 4
Why Does Clay have a high cation exchange capacity
Why Does Clay have a high cation exchange capacity? It influences the soil’s ability to hold onto essential nutrients and provides a buffer against soil acidification Soils with a higher clay fraction tend to have a higher CEC Sandy soils rely heavily on the high CEC of organic matter for the retention of nutrients in the topsoil Why is a high cation exchange Number better forThe capacity of the soil to hold and exchange cations is determined by the amount of clay and/or humus that is present These two colloidal (negatively charged) substances are essentially the cation warehouse or reservoir of the soil Sandy soils with very little organic matter (OM) have a low CEC, but heavy clay soils with high levels of OM have a much greater capacity to holdCation Exchange Capacity (CEC)

Fundamentals of Soil Cation Exchange Capacity (CEC)
Defining Cation Exchange Capacity Cations held on the clay and organic matter particles in soils can be replaced by other cations; thus, they are exchangeable For instance, potassium can be replaced by cations such as calcium or hydrogen, and vice versa The total number of cations a soil can holdor its total negative chargeis the soil's cation exchange capacity TheClay content and the ability to reversibly retain cations affect many essential chemical and physical properties of soil, such as pH buffering and carbon sequestration Cation exchange capacity (CEC) and base saturation are also commonly used as criteria in soil classification However, determination of CEC and particlesize distribution is labo rious and not included inEstimating cation exchange capacity and clay content from
