Salts are compounds formed when positively charged cations such as sodium (Na⁺), calcium (Ca²⁺), magnesium (Mg²⁺) and potassium (K⁺) combine with negatively ...
Soils have a natural characteristic called the cation exchange capacity (CEC) that allows them to hold (and exchange) cations (e.g., Ca+2 or Na+). These cations are held tight enough on the CEC that ...
THE cation exchange capacity of soils is due to inorganic constituents such as clay minerals, hydrous oxides, primary and secondary minerals and to organic matter. Estimates of the contribution of ...
