Cation exchange capacity (CEC) is a fundamental soil property used to predict plant nutrient availability and retention in the soil. It is the potential of available nutrient supply, not a direct measurement of available nutrients. the soil pH, the CEC associated with soil organic matter is called pH-dependent CEC. This means that the actual CEC of the soil will depend on the pH of the soil. Given the same amount and type of organic matter, a neutral soil (pH ~7) will have a higher CEC than a soil with e.g. pH 5, or in other words, the CEC of a Cation Exchange Capacity (CEC) CEC, as reported by nearly all soil testing laboratories, is a calculated value that is an estimate of the soils ability to attract, retain, and exchange cation elements. It is reported in millequivalents per 100 grams of soil (meq/100g).

CEC is the total capacity of a soil to hold exchangeable cations. CEC is an inherent soil characteristic and is Cation Exchange Capacity (CEC) refers to the total number of exchangeable cations that a soil can hold at any one time. The exchangeable cations are bound to clay minerals and humus colloids. In neutral to weakly acidic soils, calcium (Ca), magnesium (Mg), potassium (K) and Cation Exchange Capacity (CEC) and Anion Exchange Capacity (AEC). CEC and Less Weathered Soils of Hawaii.

Two colloidal substances, clay and humus, are present in soil essentially for its cation exchange capacity (CEC) since they serve as a cation warehouse or reservoir of the soil.

Cation exchange is derived from negative charges on soil clay and organic matter particles that attract positively charged elements, or cations. The total capacity of the soil to hold cations, measured in units of negative charge per unit of soil, is called “cation exchange capacity”, or CEC. It influences the soils ability to hold improve CEC in sandy soil is with the addition of organic matter. Organic matter has a very high CEC, potentially ranging from 250-400 meq/100g. Cation Exchange Capacity The CEC of a soil is the sum of each cation measured in meq/100g. It is not valid to add measures of other units to calculate CEC. Procedure for Cation Exchange Capacity (CEC) Determination in Soil Samples . 1.

The cation exchange capacity (CEC) of a soil is a measure of the quantity of negatively charged sites on soil surfaces that can retain positively charged ions
