TL;DR: In this paper, eight soils were studied for adsorption reactions of zinc and evaluated for their quantity, intensity and supply parameters for zinc, showing that with the addition of increasing amounts of zinc there was a simultaneous increase in the equilibrium concentration, adaption, percent saturation, and supply parameter of zinc.

Abstract: Eight soils were studied for adsorption reactions of zinc and evaluated for their quantity, intensity and supply parameters for zinc. With the addition of increasing amounts of zinc there was a simultaneous increase in the equilibrium concentration, adsorption, percent saturation of adsorption capacity and supply parameter of zinc. Multiple regression analysis revealed that in all soils quantity, intensity and equilibrium concentration were the main parameters accounting for the supply of zinc. Light loam (1), silty medium loam (6) and silt loam (7 and 8) soils having comparatively higher values for the adsorption maxima, bonding energy constant and differential buffering capacity of the soils will require higher rates of zinc to change in the solution concentration. For an ecological point of view this means a reduction of Zn toxicity.
