Abstract :The phosphorus adsorption characteristics of 11 widespread soil series from Gaziantep Kayacık Plain were investigated and these characteristics were evaluated with regard to various soil properties and phosphate minerals. Langmuir adsorption isotherms were used to determine the phosphorus-adsorption characteristics of the soils. The soils were equilibriated with solutions containing phosphorus at different concentrations at constant temperature, and the equilibrium phosphorus concentrations of the solution phases insert ignore into journalissuearticles values(C); and the amounts of adsorbed phosphorus insert ignore into journalissuearticles values(x/m); at these concentrations were determined. The adsorption maxima insert ignore into journalissuearticles values(b); and adsorption-energy coefficients insert ignore into journalissuearticles values(k); of the experimental soils were calculated from C and the x/m values using the linear form of the Langmuir adsorption isotherm. The calculated b values of the soils varied from 58.1 to 113.3 mg/g, and the k values varied from 9.1 to 153.5 ml/mg.
