Popis:	Surface zinc (Zn) adsorption is an important process that regulates the Zn concentration in the solution. The adsorption mechanism along with interacting cations and anions controls the concentration of Zn in the soil solution, which is immediately available to the plant roots. Therefore, the effect of supporting electrolytes on Zn adsorption was studied for eight benchmark soils of Punjab in northwest India. The investigation was undertaken in the presence of 0.01 M sodium sulfate (Na2SO4), 0.03 M sodium chloride (NaCl), 0.03 M sodium nitrate (NaNO3), and 0.01 M potassium sulfate (K2SO4) to study the effect of sulfate (SO4 2–), chloride (Cl–), nitrate (NO3 –), sodium (Na+), and potassium (K+). The greatest amount of Zn adsorbed in the presence of different anions was in the arid series (Gahri Bhagi, Jassipauwali) followed by the semi-arid series (Fatehpur, Kanjli) and subhumid series (Dhar, Chamror). The extent of adsorption in the presence of various anions in most of the soils followed the order as SO4...
