Abstract/Contents:"Cations were desorbed from root exchange sites of ryegrass (Lolium multiflorum Lam. cvs. Gulf, Marshall, Urbana, and Wilo) using BaCl2, BaCl2-triethanolamine, NH4OAc, and KCl. Results were analysed using multivariate analysis of variance. Ba+2-containing desorbents displaced more Ca+2 while monovalent desorbents displaced more exchangeable monovalent cations. The sum of adsorbed cations was significantly correlated with root exchange capacity (CEC) as determined by the H+ titration procedure, although slightly larger values were obtained with all desorbents. Lower CEC values were obtained for ryegrasss cultivars less sensitive to Al."
