The colloid fraction and cation-exchange capacity in the soils of Vojvodina, Serbia [PDF]

open access: yesRatarstvo i Povrtarstvo, 2015
The colloidal complex of soil consists of humus and clay, the most important acidoids which are able to create the bonds between oppositely charged ions (cations) through the forces strong enough to provide protection from leaching, and also weak enough ...

Exchange Characteristics of Lead, Zinc, and Cadmium in Selected Tropical Soils

open access: yesInternational Journal of Agronomy, 2014
Conducting binary-exchange experiments is a common way to identify cationic preferences of exchangeable phases in soil. Cation exchange reactions and thermodynamic studies of Pb2+/Ca2+, Cd2+/Ca2+, and Zn2+/Ca2+ were carried out on three surface (0–30 cm)
