Our specific objectives were to generate P sorption isotherms and Langmuir parameters Qmax and k of A and B horizon soils from locations across the tropical climate zone, and to determine whether any soil characteristics significantly contributed to the variation of observed soil P sorption parameters.

In order to predict the behavior of adsorption isotherms, several authors have proposed empirical and theoretical mathematical models to fit the equilibrium moisture curves of various products as a function of the water activity (Bezerra, Costa, Afonso, Maia, & Clemente, 2011).

In order to achieve that, first, the sodium [R.sub.d] is experimentally determined using undisturbed sandy columns and then the [R.sub.d] were determined based on the methods proposed by Freeze and Cherry (1979), by van Genuchten and Parker (1984), by the fit of the sorption isotherms models to the experimental data obtained from column experiments, and by fitting the analytical solution of the ADE to the experimental data.
