A simple laboratory technique was developed to determine the effectiveness of surfactants for Zn absorption enhancement by leaf tissues. Soybean leaf disks were floated on a 0.1 mMZnSO4‐ 0.5 mMCaSO4solution containing a surfactant. Different concentrations of six surfactants were studied. In addition to determining the enhancement of Zn absorption with different concentrations of surfactants, it was possible to determine the possible damaging effect if the surfactant concentration was too high.
