“…The ability of chemical models to describe the mechanism of B adsorption is obviously much more than empirical adsorption isotherm equations. Previous studies have investigated B adsorption using a constant capacitance model (CCM) as one of the mechanistic models (Goldberg et al 2000(Goldberg et al , 2004(Goldberg et al , 2005. These models make a connection between surface complexation constants and some soil properties such as specific surface area, organic and inorganic carbon, and Al and Fe oxide contents (Goldberg et al 2008).…”

“…These models make a connection between surface complexation constants and some soil properties such as specific surface area, organic and inorganic carbon, and Al and Fe oxide contents (Goldberg et al 2008). The empirical isotherm equations were used to predict B adsorption with changing pH (Goldberg et al 2000) and equilibrium solution B concentration (Goldberg et al 2004). Thus, in comparison with empirical equations, chemical models can be used to independently predict and describe B adsorption by soils.…”

“…Although adsorption of B has been studied in numerous researches using empirical equations (Keren and Mezuman 1981;Elrashidi and O'Connor 1982;Goldberg and Forster 1991;Majidi et al 2010), B surface complexation modeling of soil constituent assemblages has less been investigated (Goldberg 1999;Goldberg et al 1993Goldberg et al , 2000Goldberg et al , 2004.…”

This study aimed to evaluate boron (B) adsorption and the capacity of a surface complexation model for simulating this process in calcareous soils. Ten surface soils were collected from different land use areas in Hamedan, Western Iran, to characterize B sorption by soils. The mean B adsorbed by the sample soils varied from 8.9 to 32.8 %. Two empirical models including linear and Freundlich equations fitted well to the experimental data. The linear distribution (K d ) values varied from 1.32 to 6.86 L kg -1 , while the parameters of Freundlich equation including n and K Fr ranged from 1.16 to 1.33 and 3.31-16.81, respectively. The comparison of two empirical models indicated that B adsorption followed a nonlinear pattern. The soil organic matter had positive correlations with Freundlich and linear distribution coefficients. However, empirical models were not suitable for explaining the mechanism of B adsorption, so a surface complexation model was used to simulate and predict the B adsorption process. B adsorption modeling was conducted using Visual MINTEQ and PHREEQC, based on the assemblage of major surface components (hydrous ferric oxides, aluminum hydroxides, calcium carbonate, and humic acids). B adsorption was successfully modeled by surface complexation. The significant contribution of organic matter to B complexes was resulted from both experimental data and mechanistic modeling.

“…The choice of the C 1 value is arbitrary, and it is recommend to use the best fit values (~1.0 F m -2 ) (Hayes et al, 1991). We chose to use the C 1 value of 1.06 F m -2 (derived from Al oxides) (Westall and Hohl, 1980), which is usually used for soil modeling (Goldberg et al, 2000).…”

intrinsic equilibrium constants for 22 representative brazilian oxisols were estimated from a cadmium adsorption experiment. Equilibrium constants were fitted to two surface complexation models: diffuse layer and constant capacitance. intrinsic equilibrium constants were optimized by fiteQl and by hand calculation using Visual minteQ in sweep mode, and excel spreadsheets. data from both models were incorporated into Visual minteQ. constants estimated by fiteQl and incorporated in Visual minteQ software failed to predict observed data accurately. however, fiteQl raw output data rendered good results when predicted values were directly compared with observed values, instead of incorporating the estimated constants into Visual minteQ. intrinsic equilibrium constants optimized by hand calculation and incorporated in Visual minteQ reliably predicted cd adsorption reactions on soil surfaces under changing environmental conditions.

The boron (B) availability in soils, B uptake and possible B interactions with phosphorus (P) were studied in a pot experiment with increasing P rates. Three soil types of different characteristics were used for the experiment that lasted two years. The two soil tests were used in the experiment – Mehlich 3 and NH4-acetate. Significant positive correlations were found between barley dry matter yield, B content in plants and B uptake under increasing P treatments (P ≤ 0.001). The significant relationship for B content (P ≤ 0.001) was obtained between the used soil tests for all tested soils. A decrease of soil B content in soils under increasing P doses was determined. NH4-acetate soil test showed a significant relationship between B and P contents (P ≤ 0.001) within the studied soils in comparison with the Mehlich 3 method. Considering individual soils, the NH4-acetate test showed more often higher significance in comparison with the Mehlich 3 test. The interactions between P and B in soils should be taken in consideration when deciding about the phosphorus fertilization.
