Title:
Cation asorption and exchange on plant roots
Publication date:
1982
Summary:
Cation exchange capacity (CEC), electrometric titration curves and adsorption isotherms with respect to potassium were studied on roots of rice, pearl millet, chillies, lady`s finger, cotton, sunflower, peanut and green gram. Titration curves for the lower CEC crops (rice and pearl millet) tended to be slightly smooth with less prominent inflexion points, while those for the higher CEC group (lady`s finger, cotton, sunflower and legumes) showed different inflexion points. The bonding energy for potassium was the highest for rice roots, followed by cotton and sunflower, relatively lower bonding being noted on roots of peanut, chillies and lady`s finger. A close association of root CEC, patttern of electrometric titration curves and adsorption isotherms for K were observed for the crops under investigation.
