cation area density in soil
area densityhttp://purl.obolibrary.org/obo/PATO_0001351soilcation exchange capacity,CECCation exchange capacity is a measure of the total negative charges within the soil that adsorb plant nutrient cations. In this case, cations refers to the the basic cations, calcium (Ca+2), magnesium (Mg+2), potassium (K+1) and sodium (Na+1) and the acidic cations, hydrogen (H+1) and aluminum (Al+3).http://extension.uga.edu/publications/detail.cfm?number=C1040
