Calculate your CEC

Calculate your CEC. Please note: The Cation Exchange Capacity (CEC) calculation in the following form uses a straight conversion from parts per million (ppm) of each element to milliequivalents per 100 grams (meq/100g). No factors are employed. If it appears there's a discrepancy between the calculation below and the CEC offered on your analysis report, the lab may be using one or more ...

Soil Cation Exchange Capacity (CEC)

This explains why ions, the positively charged nutrients, find an easy home in the soil while anions, negatively charged nutrients, are repelled and easily leached out of the soil. Cations Anions Cations include everything from hydrogen, with a +1 positive charge, to aluminum, with a +3 positive charge. Anions include phosphate, nitrate, and other essential elements that hold a 1 or 2 ...

Determination of Cation Exchange Capacity from Soil Water ...

Cation exchange capacity (CEC) has a significant influence on the physical and chemical behavior of soil. Quantifiion of the CEC is an essential yet challenging task. A new methodology for the determination of the CECs of soils by using the soil water retention curve (SWRC) in the extremely high suction range is presented. The methodology is based on a theoretical SWRC model that explicitly ...

Cation Exchange Capacity (CEC): Meaning, Concept and Its ...

Cation exchange capacity (CEC) is the amount of exchangeable ions per unit weight of dry soil. It is measured in milliequivalents (me) of ions per 100 gms of soil (recently C mol (P +) kg 1 soil). So it is the capacity of soil colloidal material in exchanging all its ions with the ions of the soil solution.

CATIONS and CATION EXCHANGE CAPACITY Chemistry

laboratories measure CEC directly and others calculate it as CEC by bases. Cation exchange capacity is commonly measured on the fine earth fraction (soil particles less than 2 mm in size). In gravelly soils the effective CEC of the soil as a whole is diluted, and if only the fine (clay) fraction is analysed, reported CEC values will be higher than actual field values. Measuring CEC involves ...
